Utilize LiDAR for High-Precision Elevation Data #29

This could potentially serve as the foundation for a TFG.

It appears that SRTM doesn't cover the entirety or nearly the entirety of the globe, leading to anomalous elevation data in certain countries. A viable solution to this issue could be the adoption of LiDAR technology. The use of LiDAR is interesting to calculate the 2D propagation and have elevations of higher precision, the issue is to have a complete dataset because each government of each country makes its own dataset and there does not seem to be a complete one for all or almost all the world as with SRTM.
