Radar Tower

The Radar Tower is a building which is used solely for revealing a circular area around itself on the Map.

After being powered, it scans the surrounding area every five minutes up to 10 times, increasing in range with each scan. The starting range for its scans are based on the tower's line-of-sight from the tip of the tower to the ground, so placing it at the highest elevation possible is recommended for maximum efficiency. Any terrain at an elevation higher than its tip or an area blocked by a terrain feature will not be revealed.

Players should be cautious while climbing the Radar Tower due to its tricky ladders, as falls can be fatal.

Coverage
where h = -18 m when referenced to the sea level.
 * A radar tower scans in a 3D conical shape, measured from its antenna. Means its range can reach further at ravines or valleys and is reduced for high grounds, even if the high ground is below the radar antenna.
 * The coverage of the radar tower increases with height, so it is always preferred to build it on high ground, such as on top of a rock spire. It can only scan areas that are at a lower elevation than the tower antenna, and in the line-of-sight.
 * Its coverage radius, R (meter), is 1000 as of update 6.
 * Prior to update 6, radius was measured from the sea level, based on its building's base height, h (meter), was:

Coverage radius, R is capped at 1,000 meters regardless of tower base height, or 4 km diameter. As such, at least 10 Radar towers are needed to fully reveal the entire map.

Scanning
Radar Towers, once powered, will immediately reveal all nodes and show the collectibles, flora and creatures detected in its scanning area as well as displaying the nodes and removing the fog of war in the area on the Map. The radar tower must stay powered to keep the nodes visible, but the fog of war will not return.

Trivia

 * It features a ladder separated into few sections. Using the ladders, pioneers can climb up to 76 meters. The remaining height has to be climbed with Jetpack.
 * Both the Radar Tower and the Space Elevator have a collision box height of 118 meters, although the latter has a much taller graphical appearance.
 * It is the only building to feature multiple Indicator Light, counting 3. All of them display the same state at the same time.
 * The Indicator Light which extends out sideways near the tip of the tower is not counted towards the collision box.
 * It has been revealed on stream that the ladder of the tower was made by Jace and was a prototype that made it to the game and will be replaced eventually.
 * The 420 meters high (or 438 meters from sea level) can be achieved by stacking 110 foundations with 4 meter thickness vertically then build the Radar Tower on top of them.
