The radar triggers charting of the map of the force it belongs to.
  
Радар переносит на карту игрока часть территории, на которой он расположен.

It can be used to provide a small area of remote vision on the map; it also allows periodic scanning of distant chunks around it. The Radar has a high [[Electric system|power]] demand (300kW) so a radar indirectly contributes to [[Pollution]] when powered by [[Boiler]]s and [[Steam engine|steam engines]]. A radar can be continuously powered by eight solar panels and six accumulators. Seven solar panels and five accumulators is the most efficient; it gives the radar full power all but a short time in the morning, but never dips below the 20% power threshold for nearby scanning. The radar will be attacked by enemies that come within very close range, like turrets, due to its status as a military building, but will not attract biters from long range like polluting structures do. The radar will show enemy lifeforms and structures, as well as [[Train|trains]], [[Car|cars]], and other [[player]]s in the scanned area.

== Nearby Pulse Scanning ==
Радар потребляет много [[Electric system/ru|электроэнергии]] - 300кВт, то есть косвенно влияет на загрязнение, когда источником энергии являются [[Boiler/ru|бойлеры]] и [[Steam engine/ru|паровые двигатели]]. Радар может использовать в качестве постоянного источника питания восемь [[Solar panel/ru|солнечных батарей]] и шесть [[Accumulator/ru|аккумуляторов]]. Семь солнечных батарей и пять аккумуляторов тоже запитают радар на полную мощность, кроме короткого периода утром, однако уровень мощности никогда не упадёт ниже 20% необходимого для сканирования ближайших территорий. Радар будет атакован [[Enemies/ru|врагами]] подошедшими слишком близко, также как и турели, так как он является военным строением, однако он не будет привлекать кусак с большого расстояния так, как это делают [[Pollution/ru#Источники загрязнения|непосредственные источники загрязнения]]. Радар покажет вражеские формы жизни и структуры также хорошо, как [[Trains/ru|поезда]], [[Car/ru|машины]], и других [[player/ru|игроков]] в сканируемой области.

The Radar continuously charts an area of 7×7 [[Chunk]]s (224×224 [[Tile]]s), centered on the chunk the radar occupies. This nearby area is updated as a single pulse approximately every second. At reduced power levels, this nearby pulse scan will take longer, which can lead to 'blinking' on the player's map similar to the long range scan. This is particularly noticeable at dawn and dusk on solar powered radar stations.
 +
 
 +
At 20% power the radar will pulse about every 4 seconds which will still keep the nearby area continuously lit on the map, but will provide reduced detail. 20% power can be achieved by a single [[solar panel]], or by using one isolating accumulator for every 5 radars.

The Radar charts one distant [[Chunk]] every time the sector scanning progress bar fills. This will take 33.333 seconds, if the Radar is receiving full power. Mouse-over or click-open the radar details to see this progress bar. Long range scanning is visible on the map as a single chunk lighting up for several seconds, then slowly darkening.

* It scans the unexplored chunks first, represented by the black areas on the map. Note that it also generates the chunks if they weren't generated at the time of the scan.
 +
* One chunk scan takes 10 MJ of energy to complete. Since the Radar draws 300 kW of power, it takes 10 MJ ÷ 300 kW = 33.333 seconds to scan one chunk.
 +
* This is done in an 29×29 chunks around the Radar, excluding the nearby 7×7 chunks.
 +
** With a total number of 797 chunks (29×29 − 7×7), it takes one radar '''7 hours 20 minutes''' to complete one full scan cycle.
 +
* If everything is already explored it continues to scan by re-scanning the longest-ago scanned chunk within range.
 +
* Multiple radars will share long-range chunks, reducing the amount of time it takes to complete long-range survey scanning.
 +
** This is a smart process, meaning that the radars will not scan chunks currently being scanned by other radars.

Something easily missed is that Radars grant sight of a square area around them. This is good for keeping tabs on distant bases if they get attacked and to see how big the attack is. The radar's displayed area updates once every second, so keeping one or two around your base could prove to be an early warning system. Keep in mind the update rate for the displayed area of the radar is not the same as the rate at which the radar will reveal unexplored terrain, which updates once every ~30 seconds. You can see the displayed area coloured lighter in the image below, taken from map view.

If the contents of a chunk changes between two ticks, the content of that chunk is "charted" into the map. The map is just a bitmap, a picture. You can see the entities moving, you can see enemies walking. Every entity is represented by one or more pixels. Not every entity is drawn. Users can recognize what is drawn because of the color.

 +
 
 +
Once a scan for a chunk is triggered, it keeps actively charted for '''10 seconds'''. This effect can also be seen in the map of the chunk highlighted and dims within 10 seconds to a greyed out version of the chunk.
 +
 
 +
If charting is not repeated within the 10 seconds, the charting process stops for this chunk after 10 seconds and is not longer updated. What you see after that time is the last charted picture for that chunk (also called "fog of war").

 +
=== Charting of Vehicles ===
 +

Even in the fog of war you can see the last charted position of vehicles. Trains last positions are not charted, because they normally always move after the charting stops.

The [[World_generator#Generating_new_Chunks|World Generator]] creates a "border" of invisible chunks around each chunk, that becomes active at some time. Active chunks are those that become charted or those that are active because the pollution spreads onto them.

The radar triggers charting of the map of the force it belongs to.

It can be used to provide a small area of remote vision on the map; it also allows periodic scanning of distant chunks around it. The Radar has a high power demand (300kW) so a radar indirectly contributes to Pollution when powered by Boilers and steam engines. A radar can be continuously powered by eight solar panels and six accumulators. Seven solar panels and five accumulators is the most efficient; it gives the radar full power all but a short time in the morning, but never dips below the 20% power threshold for nearby scanning. The radar will be attacked by enemies that come within very close range, like turrets, due to its status as a military building, but will not attract biters from long range like polluting structures do. The radar will show enemy lifeforms and structures, as well as trains, cars, and other players in the scanned area.

Nearby Pulse Scanning

The Radar continuously charts an area of 7×7 Chunks (224×224 Tiles), centered on the chunk the radar occupies. This nearby area is updated as a single pulse approximately every second. At reduced power levels, this nearby pulse scan will take longer, which can lead to 'blinking' on the player's map similar to the long range scan. This is particularly noticeable at dawn and dusk on solar powered radar stations.

At 20% power the radar will pulse about every 4 seconds which will still keep the nearby area continuously lit on the map, but will provide reduced detail. 20% power can be achieved by a single solar panel, or by using one isolating accumulator for every 5 radars.

Long Range Survey Scanning

The Radar charts one distant Chunk every time the sector scanning progress bar fills. This will take 33.333 seconds, if the Radar is receiving full power. Mouse-over or click-open the radar details to see this progress bar. Long range scanning is visible on the map as a single chunk lighting up for several seconds, then slowly darkening.

  • It scans the unexplored chunks first, represented by the black areas on the map. Note that it also generates the chunks if they weren't generated at the time of the scan.
  • One chunk scan takes 10 MJ of energy to complete. Since the Radar draws 300 kW of power, it takes 10 MJ ÷ 300 kW = 33.333 seconds to scan one chunk.
  • This is done in an 29×29 chunks around the Radar, excluding the nearby 7×7 chunks.
    • With a total number of 797 chunks (29×29 − 7×7), it takes one radar 7 hours 20 minutes to complete one full scan cycle.
  • If everything is already explored it continues to scan by re-scanning the longest-ago scanned chunk within range.
  • Multiple radars will share long-range chunks, reducing the amount of time it takes to complete long-range survey scanning.
    • This is a smart process, meaning that the radars will not scan chunks currently being scanned by other radars.

It is possible that a new alien nest will appear in a previously scanned chunk; just because you don't see it on the map, doesn't mean it is not there.

Coverage

Something easily missed is that Radars grant sight of a square area around them. This is good for keeping tabs on distant bases if they get attacked and to see how big the attack is. The radar's displayed area updates once every second, so keeping one or two around your base could prove to be an early warning system. Keep in mind the update rate for the displayed area of the radar is not the same as the rate at which the radar will reveal unexplored terrain, which updates once every ~30 seconds. You can see the displayed area coloured lighter in the image below, taken from map view.

Charting

If a chunk is scanned by a radar or player, the image of that chunk that is copied into the map of the players of this surface force (every force has its own map).

This procedure is called "charting".

Charting Process

If the contents of a chunk changes between two ticks, the content of that chunk is "charted" into the map. The map is just a bitmap, a picture. You can see the entities moving, you can see enemies walking. Every entity is represented by one or more pixels. Not every entity is drawn. Users can recognize what is drawn because of the color.

Charting of several chunks that change each tick might have an impact on game performance, manifesting in the form of lowered UPS or FPS.

Charting Decay Time / Fog of War

Once a scan for a chunk is triggered, it keeps actively charted for 10 seconds. This effect can also be seen in the map of the chunk highlighted and dims within 10 seconds to a greyed out version of the chunk.

If charting is not repeated within the 10 seconds, the charting process stops for this chunk after 10 seconds and is not longer updated. What you see after that time is the last charted picture for that chunk (also called "fog of war").

Charting of Vehicles

Even in the fog of war you can see the last charted position of vehicles. Trains last positions are not charted, because they normally always move after the charting stops.

Vehicles are shown as a circle, with an arrow pointing in the direction that they're facing.

Invisible (black) parts of the Map

The World Generator creates a "border" of invisible chunks around each chunk, that becomes active at some time. Active chunks are those that become charted or those that are active because the pollution spreads onto them.
