I am trying to convert my irregular spaced point data (xyz) to a DEM and then, to a raster (geotiff). Because of the irregular spacing I need a triangulation first, right (so, no spaces are in the final raster)?
So the way is: XYZ -> Triangulate -> Interpolate To Raster. I have a lot of points (minimum 150.000), my raster size should be 0.25 x 0.25m or smaller. I need a way to do this with open source / free tools!

- LASTools (las2dem) - works great, is extremely fast extremely slow as well.
