 This utility generates an ASCII-raster file based on a 2D surface mesh. A raster is superimposed on the mesh and pixel values are set to the surface elevation at each pixel's position. If no mesh element is located beneath a pixel it's value is set to NODATA.

 This utility rasterises an existing 3D mesh at a given resolution. The result is a (quasi-)structured grid (consisting of hexahedral elements) with the same extent as the input mesh. Cell properties are mapped onto the grid (sampled at centre-points of each cube), while node properties are ignored. For large raster sizes,  an undersampling of the original mesh is possible.

 This utility uses two input DEMs (i.e. raster files of digital elevation models) located at the exact same spatial position but at different elevation and calculates a specified number of raster DEMs located at equidistant distance between them (i.e. for n=1, one new raster located precisely in the middle will be created).
