Uranium ore and crude oil are set to low frequency and high size. Water has a very low frequency and a big size.

Terrain beyond the bound is impassible blackness. While pollution will be absorbed into the blackness biters will continue to only spawn on land.

Resources are all 300% Frequency, 50% Size, 200% Richness. Water is 25% Coverage and Size. Starting Area Size is 300%. <br /> <br /> === Island ===<br /> The world generated is an archipelago completely surrounded by water. By adjusting only the island size % and Starting Player Area, initial biter bases can be confined to islands to make it easier to earn timed and biter-related [[Achievements|achievements]].<br /> <br /> Difference from default: Terrain Map Type is Island, 100% Scale.<br /> <br /> == Manual configuration ==<br /> === Basic settings ===<br /> ==== Peaceful mode ====<br /> The [[enemies]] don't begin fights, only responding if the player hits them. Additionally, when a map is in peaceful mode, the enemies will not [[Enemies#Expansions|expand]].<br /> <br /> ==== Enable replay ====<br /> : ''{{Main|Replay system}}''<br /> Record all the actions that the player(s) perform during the game, so that they can later be played back as essentially a timelapse of the save file.<br /> <br /> ==== Map-width and -height ====<br /> If the player limits the width and/or height they may generate maps with finite resources and area. Another option is to make the world infinite in only one axis, this is commonly referred to as a ''ribbon world''.<br /> <br /> ==== Map seed ====<br /> <br /> This is the starting value for the random number generator that Factorio uses for generating the world based on the generation settings. Know that 'random number' is really a misnomer in Factorio and on computers in general, as they aren't really random, instead being calculated with complicated algorithms that require a seed as starting value (For more detail, see http://en.wikipedia.org/wiki/Random_seed).<br /> <br /> So even with the same map-exchange string but a different seed maps can change dramatically, or appear very similar. It's up to chance. In order to get a true copy of a world, giving the map exchange string and allowing the string to fill out the seed is important.<br /> <br /> ==== Map exchange string ====<br /> <br /> A map exchange string generally looks like this:<br /> <br /> &gt;&gt;&gt;eNpjYBBg0GdgYGBm5mFJzk/MYWZm4UrOLyhILdLNL0plZmTmTC4q<br /> TUnVzc/MYWFmZktJLU4tKmEGqkrJBNNcqXmpuZW6SYnFqUAea3pRYnE<br /> xkMGRWZSfBzKBEai0ODEvBSRZXJKfB1TFyFpSlJoKUsVdWpSYl1maC7<br /> aKhZmBMcvcibmhRY4BhP/XMxj8/w/CQNYFoBNBGORSBkagAAywJudkp<br /> qUxMCg4gjAjI2O1yDr3h1VT7Bkh8noOUMYHqEjEbqjIg1YoI2I1lNFx<br /> GMpwmA9j1MMY/Q6MxmDw2R7BgNhVAjQZagmHA4IBkWwBSTIy9r7duuD<br /> 7sQt2jH9Wfrzkm5Rgz5gpG+orUPreDijJDtTAyAQnZs0EgZ0wHzDAzH<br /> xgD5W6ac949gwIvLFnZAXpEAERDhZA4oA3MHgE+ICsBT1AQkGGAeY0O<br /> 5gxIg6MaWDwDeaTxzDGZXt0f6g4MNqADJcDESdABNhCuMsYocxIB4iE<br /> JEIWqNWIAdn6FITnTsJsPIxkNZobVGBuMHHA4gU0ERWkgOcC2ZMCJ14<br /> wwx0BDMEL7DAeMG6ZGRDgg/3WD0/SAKZ2kr0=&lt;&lt;&lt;<br /> <br /> The map exchange string can be used to share all map generation settings between different players. The player can paste the string (using {{Keybinding|ctrl|V}}) into the map exchange string field and the game will set the generation settings to the settings saved in the string, resulting in a complete copy of the map when generated.<br /> <br /> The map exchange string can be retrieved from save files by going into the load game screen, selecting the desired map, clicking the Map Exchange String button in the lower left corner and copying the string from the window that pops up.<br /> <br /> For a technical description of the map exchange string, see [[map exchange string format]].<br /> <br /> === Resource and terrain settings ===<br /> ==== Frequency ====<br /> <br /> For resources, frequency determines the frequency of ore/oil patches. The higher the frequency, the more patches can be found in a given area. Although the ore patches are of a smaller size, a higher frequency still results in more ore tiles being generated.<br /> <br /> Frequency modifies the area of each deposit and the number of deposits. If resource frequency is increased, each of the deposits is smaller and has less resources in total (because it covers less area) and deposits are very common. If resource frequency is decreased, the deposits are larger but more rare.<br /> <br /> Terrain, including enemy bases and trees, is affected in the same way: The higher the frequency, the more terrain &quot;blobs&quot;/nest clusters/forests can be found in a given area, while their sizes decrease with higher frequency.<br /> <br /> Cliffs are affected in a similar way: The higher the frequency, the more cliffs can be found. However, the overall cliff area size increases with higher frequency, while the cliff &quot;lines&quot; are broken up more often, meaning that higher frequencies result in many big cliff blobs composed of short cliff &quot;lines&quot;.<br /> <br /> ==== Size ====<br /> For resources, the size setting adjusts the size of generated ore/oil patches.<br /> <br /> It's as simple as it seems — Small size would means small ore/oil patches, large means large ore/oil patches, thus increasing the resource count in a given area. Note that ore/oil patch size is also affected by frequency.<br /> <br /> &lt;!-- A note on documenting bugs here: Normally this is should not be done. However, these bugs have existed for longer than half a year, and are expected to be fixed in 0.17 at the earliest. Since they have a big impact, the behaviour must be documented. So, I am taking the freedom to overrule the style guide in this case. -- [[User:Bilka|Bilka]] ([[User talk:Bilka|talk]]) - &lt;span style=&quot;color:#FF0000&quot;&gt;Admin&lt;/span&gt; 19:30, 6 June 2018 (UTC)<br /> --&gt;[https://forums.factorio.com/55178 Due to a bug], enemy bases are currently not affected by the size setting. Their size can only be changed by changing their frequency.<br /> <br /> The other terrain types, including water and trees, are affected the same way as resources.<br /> <br /> [https://forums.factorio.com/54664 Due to a bug], the effect of the size setting on cliffs cannot be reliably predicted. Any size setting above small may lead to cliffs spawning in the starting area. Big and very big size seem to always spawn cliffs everywhere, while medium size and below may not spawn any cliffs.<br /> <br /> The following table shows how the frequency and size settings affects the generation of ore patches.

Generally, this results in at least one confirmed ore source each of [[coal]], [[iron ore]], [[copper ore]], and [[stone]], always results in a water source, and always removes biter nests from spawning for an area around spawn. [[Uranium ore]] and [[crude oil]] should not spawn in the starting area. Cliffs should not spawn in the starting area[https://www.factorio.com/blog/post/fff-219], but due to [https://forums.factorio.com/54664 a bug] they may spawn there. The size of the starting area is adjusted by changing the size setting.<br /> <br /> {| class=&quot;wikitable&quot;<br /> |+World generations on different starting area settings<br /> !Very small<br /> !Small<br /> !Medium<br /> !Big<br /> !Very big<br /> <br /> |-<br /> |[[File:Starting_area_very_small.png|frameless|150x150px]]<br /> |[[File:Starting_area_small.png|frameless|150x150px]]<br /> |[[File:Starting_area_medium.png|frameless|150x150px]]<br /> |[[File:Starting_area_big.png|frameless|150x150px]]<br /> |[[File:Starting_area_very_big.png|frameless|150x150px]]<br /> |}<br /> <br /> ==== Richness ====<br /> <br /> This defines the actual content of every ore patch and oil field.

The high frequency refers mainly to the noise function. Increasing the frequency increases count of resource fields and decreases their size and distance between them. This mechanism is used all through the map generation in factorio, with some adjustments. The map generator works tile by tile, so the resources are placed on a tile x if f(x) &gt; 0. The amount of resources on the tile is given by f(x) * richness.<br /> <br /> === Chunks ===<br /> <br /> A map is endless by default, though its size can be limited by height and width — see above. Because it is technically endless, the whole map is not generated from the start. Instead, a new [[chunk]] of the map is generated only when needed, similar to other procedurally generated world games.<br /> <br /> ==== Invisible chunks (fog of war) ====<br /> <br /> Outside of the visible chunk area, an invisible area of about 3 chunks wide is generated as a preloading mechanism. Enemies may be located inside these invisible chunks and can attack the player from there, while [[artillery turret]]s and [[artillery wagon|wagon]]s may automatically shoot enemy bases in these chunks if they are within their automatic range. Invisible chunks are also generated if pollution is generated heavily; the game generates (invisible) chunks as it needs to spread the pollution into the area.<br /> <br /> ==== Charting (removing fog of war) ====<br /> <br /> As long as a chunk is invisible, the part of the players map stays black. This changes when a chunk is [[Radar#Charting|charted]], which means when it is &quot;touched&quot; by a radar. This can be either the player's internal radar, which is always available and continually charts chunks around the player, or the [[radar]] entity.

In real-world terms, this is between the sizes of India and Australia (or about 40% the area of the United States, or over 10 times the area of Germany). It would take around 200 [[game-second|game-minutes]] (ca 3.3 hours real time) to reach that border from the center when riding a [[locomotive|train]] fueled with [[rocket fuel|rocket]] or [[nuclear fuel]]. This makes the world essentially endless for practical purposes.<br /> <br /> Because chunks are only generated in and close around the area revealed by radar, it is possible to reach that border without overloading your computer, as the size of the map in computer memory is dependent only on chunks actually generated.

<p>Aurelien: /* History */</p> <hr /> <div>{{Languages}}<br /> [[File:Default_123456789.png|thumb|right|An example how the world generator might create a new map: Default settings with map seed 123456789]]<br /> World generation is the procedure by which the in game landscape is generated. In short: a number of settings, editable at the start of a new world, define what that world will look like. This can dramatically alter gameplay — a new player is advised to start with the default settings before deciding to change their world.<br /> __TOC__{{Clear}}<br /> == Map generation presets ==<br /> [[File:MapGeneratorOverview.png|thumb|right|400px|Overview of the map generation screen]]<br /> A preset may be chosen instead of manually configuring the generation.<br /> === Default ===<br /> Normal settings.<br /> <br /> All terrain and resource settings set to regular/normal/medium.<br /> <br /> ==== Advanced settings ====<br /> All settings are set to their defaults:<br /> <br /> {| class=&quot;wikitable&quot;<br /> |-<br /> !

Only select this if you are a Factorio veteran.<br /> <br /> Combines &quot;Marathon&quot; and &quot;Death world&quot;.<br /> <br /> === Rail world ===<br /> Resource patches are large and spread far apart, to encourage train systems. Biters won't create any new bases or re-expand into cleared territory.<br /> <br /> Difference from default: Coal, copper ore, iron ore, and stone are set to very low frequency and big size instead of normal/medium. Uranium ore and crude oil are set to low frequency and high size. Water has a very low frequency and a big size. The evolution time factor is set to 0.000002 and enemy expansion is disabled.<br /> <br /> === Ribbon world ===<br /> The world generated is a narrow bounded stripe. Terrain beyond the bound is impassible blackness. While pollution will be absorbed into the blackness biters will continue to only spawn on land. [https://forums.factorio.com/viewtopic.php?f=23&amp;t=70766&amp;p=429600&amp;hilit=ribbon+world#p429600 Example].<br /> <br /> Difference from default: Under Advanced, the map height is set to 128. Resources are all 300% Frequency, 50% Size, 200% Richness. Water is 25% Coverage and Size. Starting Area Size is 300%. <br /> <br /> === Island ===<br /> The world generated is an archipelago completely surrounded by water. By adjusting only the island size % and Starting Player Area, initial biter bases can be confined to islands to make it easier to earn timed and biter-related [[Achievements|achievements]].<br /> <br /> Difference from default: Terrain Map Type is Island, 100% Scale.<br /> <br /> == Manual configuration ==<br /> === Basic settings ===<br /> ==== Peaceful mode ====<br /> The [[enemies]] don't begin fights, only responding if the player hits them. Additionally, when a map is in peaceful mode, the enemies will not [[Enemies#Expansions|expand]].<br /> <br /> ==== Enable replay ====<br /> : ''{{Main|Replay system}}''<br /> Record all the actions that the player(s) perform during the game, so that they can later be played back as essentially a timelapse of the save file.<br /> <br /> ==== Map-width and -height ====<br /> If the player limits the width and/or height they may generate maps with finite resources and area. Another option is to make the world infinite in only one axis, this is commonly referred to as a ''ribbon world''.<br /> <br /> ==== Map seed ====<br /> <br /> This is the starting value for the random number generator that Factorio uses for generating the world based on the generation settings. Know that 'random number' is really a misnomer in Factorio and on computers in general, as they aren't really random, instead being calculated with complicated algorithms that require a seed as starting value (For more detail, see http://en.wikipedia.org/wiki/Random_seed).<br /> <br /> So even with the same map-exchange string but a different seed maps can change dramatically, or appear very similar. It's up to chance. In order to get a true copy of a world, giving the map exchange string and allowing the string to fill out the seed is important.<br /> <br /> ==== Map exchange string ====<br /> <br /> A map exchange string generally looks like this:<br /> <br /> &gt;&gt;&gt;eNpjYBBg0GdgYGBm5mFJzk/MYWZm4UrOLyhILdLNL0plZmTmTC4q<br /> TUnVzc/MYWFmZktJLU4tKmEGqkrJBNNcqXmpuZW6SYnFqUAea3pRYnE<br /> xkMGRWZSfBzKBEai0ODEvBSRZXJKfB1TFyFpSlJoKUsVdWpSYl1maC7<br /> aKhZmBMcvcibmhRY4BhP/XMxj8/w/CQNYFoBNBGORSBkagAAywJudkp<br /> qUxMCg4gjAjI2O1yDr3h1VT7Bkh8noOUMYHqEjEbqjIg1YoI2I1lNFx<br /> GMpwmA9j1MMY/Q6MxmDw2R7BgNhVAjQZagmHA4IBkWwBSTIy9r7duuD<br /> 7sQt2jH9Wfrzkm5Rgz5gpG+orUPreDijJDtTAyAQnZs0EgZ0wHzDAzH<br /> xgD5W6ac949gwIvLFnZAXpEAERDhZA4oA3MHgE+ICsBT1AQkGGAeY0O<br /> 5gxIg6MaWDwDeaTxzDGZXt0f6g4MNqADJcDESdABNhCuMsYocxIB4iE<br /> JEIWqNWIAdn6FITnTsJsPIxkNZobVGBuMHHA4gU0ERWkgOcC2ZMCJ14<br /> wwx0BDMEL7DAeMG6ZGRDgg/3WD0/SAKZ2kr0=&lt;&lt;&lt;<br /> <br /> The map exchange string can be used to share all map generation settings between different players. The player can paste the string (using {{Keybinding|ctrl|V}}) into the map exchange string field and the game will set the generation settings to the settings saved in the string, resulting in a complete copy of the map when generated.<br /> <br /> The map exchange string can be retrieved from save files by going into the load game screen, selecting the desired map, clicking the Map Exchange String button in the lower left corner and copying the string from the window that pops up.<br /> <br /> For a technical description of the map exchange string, see [[map exchange string format]].<br /> <br /> === Resource and terrain settings ===<br /> ==== Frequency ====<br /> <br /> For resources, frequency determines the frequency of ore/oil patches. The higher the frequency, the more patches can be found in a given area. Although the ore patches are of a smaller size, a higher frequency still results in more ore tiles being generated.<br /> <br /> Frequency modifies the area of each deposit and the number of deposits. If resource frequency is increased, each of the deposits is smaller and has less resources in total (because it covers less area) and deposits are very common. If resource frequency is decreased, the deposits are larger but more rare.<br /> <br /> Terrain, including enemy bases and trees, is affected in the same way: The higher the frequency, the more terrain &quot;blobs&quot;/nest clusters/forests can be found in a given area, while their sizes decrease with higher frequency.<br /> <br /> Cliffs are affected in a similar way: The higher the frequency, the more cliffs can be found. However, the overall cliff area size increases with higher frequency, while the cliff &quot;lines&quot; are broken up more often, meaning that higher frequencies result in many big cliff blobs composed of short cliff &quot;lines&quot;.<br /> <br /> ==== Size ====<br /> For resources, the size setting adjusts the size of generated ore/oil patches.<br /> <br /> It's as simple as it seems — Small size would means small ore/oil patches, large means large ore/oil patches, thus increasing the resource count in a given area. Note that ore/oil patch size is also affected by frequency.<br /> <br /> &lt;!-- A note on documenting bugs here: Normally this is should not be done. However, these bugs have existed for longer than half a year, and are expected to be fixed in 0.17 at the earliest. Since they have a big impact, the behaviour must be documented. So, I am taking the freedom to overrule the style guide in this case. -- [[User:Bilka|Bilka]] ([[User talk:Bilka|talk]]) - &lt;span style=&quot;color:#FF0000&quot;&gt;Admin&lt;/span&gt; 19:30, 6 June 2018 (UTC)<br /> --&gt;[https://forums.factorio.com/55178 Due to a bug], enemy bases are currently not affected by the size setting. Their size can only be changed by changing their frequency.<br /> <br /> The other terrain types, including water and trees, are affected the same way as resources.<br /> <br /> [https://forums.factorio.com/54664 Due to a bug], the effect of the size setting on cliffs cannot be reliably predicted. Any size setting above small may lead to cliffs spawning in the starting area. Big and very big size seem to always spawn cliffs everywhere, while medium size and below may not spawn any cliffs.<br /> <br /> The following table shows how the frequency and size settings affects the generation of ore patches.

Generally, this results in at least one confirmed ore source each of [[coal]], [[iron ore]], [[copper ore]], and [[stone]], always results in a water source, and always removes biter nests from spawning for an area around spawn. [[Uranium ore]] and [[crude oil]] should not spawn in the starting area. Cliffs should not spawn in the starting area[https://www.factorio.com/blog/post/fff-219], but due to [https://forums.factorio.com/54664 a bug] they may spawn there. The size of the starting area is adjusted by changing the size setting.<br /> <br /> {| class=&quot;wikitable&quot;<br /> |+World generations on different starting area settings<br /> !Very small<br /> !Small<br /> !Medium<br /> !Big<br /> !Very big<br /> <br /> |-<br /> |[[File:Starting_area_very_small.png|frameless|150x150px]]<br /> |[[File:Starting_area_small.png|frameless|150x150px]]<br /> |[[File:Starting_area_medium.png|frameless|150x150px]]<br /> |[[File:Starting_area_big.png|frameless|150x150px]]<br /> |[[File:Starting_area_very_big.png|frameless|150x150px]]<br /> |}<br /> <br /> ==== Richness ====<br /> <br /> This defines the actual content of every ore patch and oil field.

The high frequency refers mainly to the noise function. Increasing the frequency increases count of resource fields and decreases their size and distance between them. This mechanism is used all through the map generation in factorio, with some adjustments. The map generator works tile by tile, so the resources are placed on a tile x if f(x) &gt; 0. The amount of resources on the tile is given by f(x) * richness.<br /> <br /> === Chunks ===<br /> <br /> A map is endless by default, though its size can be limited by height and width — see above. Because it is technically endless, the whole map is not generated from the start. Instead, a new [[chunk]] of the map is generated only when needed, similar to other procedurally generated world games.<br /> <br /> ==== Invisible chunks (fog of war) ====<br /> <br /> Outside of the visible chunk area, an invisible area of about 3 chunks wide is generated as a preloading mechanism. Enemies may be located inside these invisible chunks and can attack the player from there, while [[artillery turret]]s and [[artillery wagon|wagon]]s may automatically shoot enemy bases in these chunks if they are within their automatic range. Invisible chunks are also generated if pollution is generated heavily; the game generates (invisible) chunks as it needs to spread the pollution into the area.<br /> <br /> ==== Charting (removing fog of war) ====<br /> <br /> As long as a chunk is invisible, the part of the players map stays black. This changes when a chunk is [[Radar#Charting|charted]], which means when it is &quot;touched&quot; by a radar. This can be either the player's internal radar, which is always available and continually charts chunks around the player, or the [[radar]] entity. If a far-away and thus ungenerated chunk is charted, it will be generated, together with the above-mentioned invisible 3 chunk radius of map around it.<br /> <br /> ==== Maximum map size and used memory ====<br /> <br /> The map size is limited to 2,000 x 2,000 kilometers; internally, this is a square 2,000,000 tiles on a side, with an area of 4,000,000,000,000 (4 trillion) square tiles (assuming 1 tile = 1 meter on a side yields 2,000 x 2,000 km = 4 million square km). In real-world terms, this is between the sizes of India and Australia (or about 40% the area of the United States, or over 10 times the area of Germany). It would take around 200 [[game-second|game-minutes]] (ca 3.3 hours real time) to reach that border from the center when riding a [[locomotive|train]] fueled with [[rocket fuel|rocket]] or [[nuclear fuel]]. This makes the world essentially endless for practical purposes.<br /> <br /> Because chunks are only generated in and close around the area revealed by radar, it is possible to reach that border without overloading your computer, as the size of the map in computer memory is dependent only on chunks actually generated. If only a narrow stripe of land is explored to far away, this remains manageable.<br /> <br /> The generated chunks are fully mapped and stored in the player's RAM, which is the practical limiting factor of exploration.<br /> &lt;!-- COMMENT (invisible): This last paragraph could have an example.

Another option is to make the world infinite in only one axis, this is commonly referred to as a ''ribbon world''.<br /> <br /> ==== Map seed ====<br /> <br /> This is the starting value for the random number generator that Factorio uses for generating the world based on the generation settings. Know that 'random number' is really a misnomer in Factorio and on computers in general, as they aren't really random, instead being calculated with complicated algorithms that require a seed as starting value (For more detail, see http://en.wikipedia.org/wiki/Random_seed).<br /> <br /> So even with the same map-exchange string but a different seed maps can change dramatically, or appear very similar. It's up to chance. In order to get a true copy of a world, giving the map exchange string and allowing the string to fill out the seed is important.<br /> <br /> ==== Map exchange string ====<br /> <br /> A map exchange string generally looks like this:<br /> <br /> &gt;&gt;&gt;eNpjYBBg0GdgYGBm5mFJzk/MYWZm4UrOLyhILdLNL0plZmTmTC4q<br /> TUnVzc/MYWFmZktJLU4tKmEGqkrJBNNcqXmpuZW6SYnFqUAea3pRYnE<br /> xkMGRWZSfBzKBEai0ODEvBSRZXJKfB1TFyFpSlJoKUsVdWpSYl1maC7<br /> aKhZmBMcvcibmhRY4BhP/XMxj8/w/CQNYFoBNBGORSBkagAAywJudkp<br /> qUxMCg4gjAjI2O1yDr3h1VT7Bkh8noOUMYHqEjEbqjIg1YoI2I1lNFx<br /> GMpwmA9j1MMY/Q6MxmDw2R7BgNhVAjQZagmHA4IBkWwBSTIy9r7duuD<br /> 7sQt2jH9Wfrzkm5Rgz5gpG+orUPreDijJDtTAyAQnZs0EgZ0wHzDAzH<br /> xgD5W6ac949gwIvLFnZAXpEAERDhZA4oA3MHgE+ICsBT1AQkGGAeY0O<br /> 5gxIg6MaWDwDeaTxzDGZXt0f6g4MNqADJcDESdABNhCuMsYocxIB4iE<br /> JEIWqNWIAdn6FITnTsJsPIxkNZobVGBuMHHA4gU0ERWkgOcC2ZMCJ14<br /> wwx0BDMEL7DAeMG6ZGRDgg/3WD0/SAKZ2kr0=&lt;&lt;&lt;<br /> <br /> The map exchange string can be used to share all map generation settings between different players. The player can paste the string (using {{Keybinding|ctrl|V}}) into the map exchange string field and the game will set the generation settings to the settings saved in the string, resulting in a complete copy of the map when generated.<br /> <br /> The map exchange string can be retrieved from save files by going into the load game screen, selecting the desired map, clicking the Map Exchange String button in the lower left corner and copying the string from the window that pops up.<br /> <br /> For a technical description of the map exchange string, see [[map exchange string format]].<br /> <br /> === Resource and terrain settings ===<br /> ==== Frequency ====<br /> <br /> For resources, frequency determines the frequency of ore/oil patches. The higher the frequency, the more patches can be found in a given area. Although the ore patches are of a smaller size, a higher frequency still results in more ore tiles being generated.<br /> <br /> Frequency modifies the area of each deposit and the number of deposits. If resource frequency is increased, each of the deposits is smaller and has less resources in total (because it covers less area) and deposits are very common. If resource frequency is decreased, the deposits are larger but more rare.<br /> <br /> Terrain, including enemy bases and trees, is affected in the same way: The higher the frequency, the more terrain &quot;blobs&quot;/nest clusters/forests can be found in a given area, while their sizes decrease with higher frequency.<br /> <br /> Cliffs are affected in a similar way: The higher the frequency, the more cliffs can be found. However, the overall cliff area size increases with higher frequency, while the cliff &quot;lines&quot; are broken up more often, meaning that higher frequencies result in many big cliff blobs composed of short cliff &quot;lines&quot;.<br /> <br /> ==== Size ====<br /> For resources, the size setting adjusts the size of generated ore/oil patches.<br /> <br /> It's as simple as it seems — Small size would means small ore/oil patches, large means large ore/oil patches, thus increasing the resource count in a given area. Note that ore/oil patch size is also affected by frequency.<br /> <br /> &lt;!-- A note on documenting bugs here: Normally this is should not be done. However, these bugs have existed for longer than half a year, and are expected to be fixed in 0.17 at the earliest. Since they have a big impact, the behaviour must be documented. So, I am taking the freedom to overrule the style guide in this case. -- [[User:Bilka|Bilka]] ([[User talk:Bilka|talk]]) - &lt;span style=&quot;color:#FF0000&quot;&gt;Admin&lt;/span&gt; 19:30, 6 June 2018 (UTC)<br /> --&gt;[https://forums.factorio.com/55178 Due to a bug], enemy bases are currently not affected by the size setting.

[[Uranium ore]] and [[crude oil]] should not spawn in the starting area. Cliffs should not spawn in the starting area[https://www.factorio.com/blog/post/fff-219], but due to [https://forums.factorio.com/54664 a bug] they may spawn there.

The high frequency refers mainly to the noise function. Increasing the frequency increases count of resource fields and decreases their size and distance between them. This mechanism is used all through the map generation in factorio, with some adjustments. The map generator works tile by tile, so the resources are placed on a tile x if f(x) &gt; 0. The amount of resources on the tile is given by f(x) * richness.<br /> <br /> === Chunks ===<br /> <br /> A map is endless by default, though its size can be limited by height and width — see above. Because it is technically endless, the whole map is not generated from the start. Instead, a new [[chunk]] of the map is generated only when needed, similar to other procedurally generated world games.<br /> <br /> ==== Invisible chunks (fog of war) ====<br /> <br /> Outside of the visible chunk area, an invisible area of about 3 chunks wide is generated as a preloading mechanism. Enemies may be located inside these invisible chunks and can attack the player from there, while [[artillery turret]]s and [[artillery wagon|wagon]]s may automatically shoot enemy bases in these chunks if they are within their automatic range. Invisible chunks are also generated if pollution is generated heavily; the game generates (invisible) chunks as it needs to spread the pollution into the area.<br /> <br /> ==== Charting (removing fog of war) ====<br /> <br /> As long as a chunk is invisible, the part of the players map stays black. This changes when a chunk is [[Radar#Charting|charted]], which means when it is &quot;touched&quot; by a radar. This can be either the player's internal radar, which is always available and continually charts chunks around the player, or the [[radar]] entity. If a far-away and thus ungenerated chunk is charted, it will be generated, together with the above-mentioned invisible 3 chunk radius of map around it.<br /> <br /> ==== Maximum map size and used memory ====<br /> <br /> The map size is limited to 2,000 x 2,000 kilometers; internally, this is a square 2,000,000 tiles on a side, with an area of 4,000,000,000,000 (4 trillion) square tiles (assuming 1 tile = 1 meter on a side yields 2,000 x 2,000 km = 4 million square km). In real-world terms, this is between the sizes of India and Australia (or about 40% the area of the United States, or over 10 times the area of Germany). It would take around 200 [[game-second|game-minutes]] (ca 3.3 hours real time) to reach that border from the center when riding a [[locomotive|train]] fueled with [[rocket fuel|rocket]] or [[nuclear fuel]]. This makes the world essentially endless for practical purposes.<br /> <br /> Because chunks are only generated in and close around the area revealed by radar, it is possible to reach that border without overloading your computer, as the size of the map in computer memory is dependent only on chunks actually generated. If only a narrow stripe of land is explored to far away, this remains manageable.<br /> <br /> The generated chunks are fully mapped and stored in the player's RAM, which is the practical limiting factor of exploration.<br /> &lt;!-- COMMENT (invisible): This last paragraph could have an example. I'm sure it's not cut-and-dried, but some ballpark figure for basic orientation like &quot;if you have less than X GB of memory, you will have problems running maps where more than Y tiles on a side is explored&quot;.

In order to get a true copy of a world, giving the map exchange string and allowing the string to fill out the seed is important.<br /> <br /> ==== Map exchange string ====<br /> <br /> A map exchange string generally looks like this:<br /> <br /> &gt;&gt;&gt;eNpjYBBg0GdgYGBm5mFJzk/MYWZm4UrOLyhILdLNL0plZmTmTC4q<br /> TUnVzc/MYWFmZktJLU4tKmEGqkrJBNNcqXmpuZW6SYnFqUAea3pRYnE<br /> xkMGRWZSfBzKBEai0ODEvBSRZXJKfB1TFyFpSlJoKUsVdWpSYl1maC7<br /> aKhZmBMcvcibmhRY4BhP/XMxj8/w/CQNYFoBNBGORSBkagAAywJudkp<br /> qUxMCg4gjAjI2O1yDr3h1VT7Bkh8noOUMYHqEjEbqjIg1YoI2I1lNFx<br /> GMpwmA9j1MMY/Q6MxmDw2R7BgNhVAjQZagmHA4IBkWwBSTIy9r7duuD<br /> 7sQt2jH9Wfrzkm5Rgz5gpG+orUPreDijJDtTAyAQnZs0EgZ0wHzDAzH<br /> xgD5W6ac949gwIvLFnZAXpEAERDhZA4oA3MHgE+ICsBT1AQkGGAeY0O<br /> 5gxIg6MaWDwDeaTxzDGZXt0f6g4MNqADJcDESdABNhCuMsYocxIB4iE<br /> JEIWqNWIAdn6FITnTsJsPIxkNZobVGBuMHHA4gU0ERWkgOcC2ZMCJ14<br /> wwx0BDMEL7DAeMG6ZGRDgg/3WD0/SAKZ2kr0=&lt;&lt;&lt;<br /> <br /> The map exchange string can be used to share all map generation settings between different players. The player can paste the string (using {{Keybinding|ctrl|V}}) into the map exchange string field and the game will set the generation settings to the settings saved in the string, resulting in a complete copy of the map when generated.<br /> <br /> The map exchange string can be retrieved from save files by going into the load game screen, selecting the desired map, clicking the Map Exchange String button in the lower left corner and copying the string from the window that pops up.<br /> <br /> For a technical description of the map exchange string, see [[map exchange string format]].<br /> <br /> === Resource and terrain settings ===<br /> ==== Frequency ====<br /> <br /> For resources, frequency determines the frequency of ore/oil patches. The higher the frequency, the more patches can be found in a given area. Although the ore patches are of a smaller size, a higher frequency still results in more ore tiles being generated.<br /> <br /> Frequency modifies the area of each deposit and the number of deposits. If resource frequency is increased, each of the deposits is smaller and has less resources in total (because it covers less area) and deposits are very common. If resource frequency is decreased, the deposits are larger but more rare.<br /> <br /> Terrain, including enemy bases and trees, is affected in the same way: The higher the frequency, the more terrain &quot;blobs&quot;/nest clusters/forests can be found in a given area, while their sizes decrease with higher frequency.<br /> <br /> Cliffs are affected in a similar way: The higher the frequency, the more cliffs can be found. However, the overall cliff area size increases with higher frequency, while the cliff &quot;lines&quot; are broken up more often, meaning that higher frequencies result in many big cliff blobs composed of short cliff &quot;lines&quot;.<br /> <br /> ==== Size ====<br /> For resources, the size setting adjusts the size of generated ore/oil patches.<br /> <br /> It's as simple as it seems — Small size would means small ore/oil patches, large means large ore/oil patches, thus increasing the resource count in a given area. Note that ore/oil patch size is also affected by frequency.<br /> <br /> &lt;!-- A note on documenting bugs here: Normally this is should not be done. However, these bugs have existed for longer than half a year, and are expected to be fixed in 0.17 at the earliest. Since they have a big impact, the behaviour must be documented. So, I am taking the freedom to overrule the style guide in this case. -- [[User:Bilka|Bilka]] ([[User talk:Bilka|talk]]) - &lt;span style=&quot;color:#FF0000&quot;&gt;Admin&lt;/span&gt; 19:30, 6 June 2018 (UTC)<br /> --&gt;[https://forums.factorio.com/55178 Due to a bug], enemy bases are currently not affected by the size setting. Their size can only be changed by changing their frequency.<br /> <br /> The other terrain types, including water and trees, are affected the same way as resources.<br /> <br /> [https://forums.factorio.com/54664 Due to a bug], the effect of the size setting on cliffs cannot be reliably predicted. Any size setting above small may lead to cliffs spawning in the starting area. Big and very big size seem to always spawn cliffs everywhere, while medium size and below may not spawn any cliffs.<br /> <br /> The following table shows how the frequency and size settings affects the generation of ore patches.

Generally, this results in at least one confirmed ore source each of [[coal]], [[iron ore]], [[copper ore]], and [[stone]], always results in a water source, and always removes biter nests from spawning for an area around spawn. [[Uranium ore]] and [[crude oil]] should not spawn in the starting area. Cliffs should not spawn in the starting area[https://www.factorio.com/blog/post/fff-219], but due to [https://forums.factorio.com/54664 a bug] they may spawn there.

The high frequency refers mainly to the noise function. Increasing the frequency increases count of resource fields and decreases their size and distance between them. This mechanism is used all through the map generation in factorio, with some adjustments. The map generator works tile by tile, so the resources are placed on a tile x if f(x) &gt; 0. The amount of resources on the tile is given by f(x) * richness.<br /> <br /> === Chunks ===<br /> <br /> A map is endless by default, though its size can be limited by height and width — see above. Because it is technically endless, the whole map is not generated from the start. Instead, a new [[chunk]] of the map is generated only when needed, similar to other procedurally generated world games.<br /> <br /> ==== Invisible chunks (fog of war) ====<br /> <br /> Outside of the visible chunk area, an invisible area of about 3 chunks wide is generated as a preloading mechanism. Enemies may be located inside these invisible chunks and can attack the player from there, while [[artillery turret]]s and [[artillery wagon|wagon]]s may automatically shoot enemy bases in these chunks if they are within their automatic range. Invisible chunks are also generated if pollution is generated heavily; the game generates (invisible) chunks as it needs to spread the pollution into the area.<br /> <br /> ==== Charting (removing fog of war) ====<br /> <br /> As long as a chunk is invisible, the part of the players map stays black. This changes when a chunk is [[Radar#Charting|charted]], which means when it is &quot;touched&quot; by a radar. This can be either the player's internal radar, which is always available and continually charts chunks around the player, or the [[radar]] entity. If a far-away and thus ungenerated chunk is charted, it will be generated, together with the above-mentioned invisible 3 chunk radius of map around it.<br /> <br /> ==== Maximum map size and used memory ====<br /> <br /> The map size is limited to 2,000 x 2,000 kilometers; internally, this is a square 2,000,000 tiles on a side, with an area of 4,000,000,000,000 (4 trillion) square tiles (assuming 1 tile = 1 meter on a side yields 2,000 x 2,000 km = 4 million square km). In real-world terms, this is between the sizes of India and Australia (or about 40% the area of the United States, or over 10 times the area of Germany). It would take around 200 [[game-second|game-minutes]] (ca 3.3 hours real time) to reach that border from the center when riding a [[locomotive|train]] fueled with [[rocket fuel|rocket]] or [[nuclear fuel]]. This makes the world essentially endless for practical purposes.<br /> <br /> Because chunks are only generated in and close around the area revealed by radar, it is possible to reach that border without overloading your computer, as the size of the map in computer memory is dependent only on chunks actually generated. If only a narrow stripe of land is explored to far away, this remains manageable.<br /> <br /> The generated chunks are fully mapped and stored in the player's RAM, which is the practical limiting factor of exploration.<br /> &lt;!-- COMMENT (invisible): This last paragraph could have an example. I'm sure it's not cut-and-dried, but some ballpark figure for basic orientation like &quot;if you have less than X GB of memory, you will have problems running maps where more than Y tiles on a side is explored&quot;.
