DTM setup

DTM mesh

The terrain mesh can be made using any techniques, as long as the result follows some rules.

• the grid should be regular, there should be no deviation in the X and Y coordinates within rows and columns

✅

❌

• the X and Y coordinates do not have to be to scale as those will be defined by the Raster Spacing property in the exported file

• the Z coordinates are directly written into the exported file

---

Properties

The DTM properties define the spacing of raster points, as well as the geolocation of the terrain (Terrain Builder expects UTM coordinates).

For more information, see the DTM properties page.
