3D Maps and Analysis
Since its beginnings, GIS has relied on 2D maps. They were what we created and where we performed our analyses. Recently, this is changing. More and more, we are having to take the third dimension, Z, into account. This is because the world is becoming more crowded. Our infrastructure is stacking up upon itself, both above ground and below. So, the need to track and view data in 3D is increasing. Supporting technologies, such as Light Detection and Ranging (LiDAR), Unmanned Aerial Vehicles (Drones/UAS/UAV), Building Information Models (BIM), Digital Twins, and increasing computer power are also adding to this push.
