terraintool - 1.13-2 main

This tool generates terrain meshes for cave survey tools from online
terrain altitude datasets. It uses the NASA SRTM and European ASTER datasets. The
relevant data is downloaded and 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) format.
It is written in java.
