When you move the cursor, the Northing, Easting and Elevation info appears in the lower right hand corner. We will have to point our cursor in severa spots inside the selection box to extract this data. The selection box does not give us any information concerning the width, length and elevation of the selected area and Unity will need this information. We use the free program 3DEM, which you can download here.ΔΆ. Convert DEM to Terragen File The first step is to convert the DEM into a Terragen file. For many users of Unity, the most cost effective solution is to use a two step rocess using Terragen and 3DEM, but if you can obtain a heightmap from DEM by any other means, you can skip to the Import into Unity section.
