terraintool

Generates survex/therion terrain models from SRTM/NASADEM data.

Description

This tool generates terrain meshes for cave survey tools from online terrain altitude datasets. It uses the NASA NASADEM dataset (Reprocessed SRTM data with the voids removed using ASTER data). Automatic download is no longer possible, so an account must be created and required tiles downloaded for the program to use. The relevant areas are excerpted, geolocated to the desired co-ordinate system, resampled to a mesh grid, an offset to local grid added if required, the result displayed, and saved in survex (.svx), therion (.th), or csv format. It is written in java.
