Testing my implementation of global virtual airspace for autonomous drone navigation.
1. Grand Canyon, AZ, US
2. Sobótka mountain, S-W Poland (with a few airspace elements in the background)
3. Bellevue, WA, US
Blue net is USGL for symmetric navigation properties based on 10m DEM satellite radar and airborne LIDAR data.
Ground level is generated by obeying a few simple geometric principles that guarantee an automated system with specified climbing and cruise speed capabilities will be able to navigate safely in all directions (here 50mph, 1:10 climb slope, 1.12 max G factor).
