Today I tried to create a section of Terrain in Unity using a Digital Elevation Model. I downloaded the DEM file from GeoGratis and converted it to a GeoTiff file using an open source application called QGIS. Once I had this GeoTiff, I was able to use this to create a mesh using the height information from the image. It turned out ok, but it is quite a dense mesh and probably is not the best way to create terrain in Unity. The built in Terrain tools in Unity are great, but I am curious to see what other ways of implementing terrain there are.
