Hello, trying to generate a DEM from a photogrammetric vector input file (elevation points, contour lines, and breaklines), I decided to run the v.triangle addon. The main reason is the local topography has many ridges and deep gulleys and I want to incorporate a breaklines vector map in my interpolation process.
Unfortunately v.triangle output is a TIN, and I wish I could turn it into a raster elevation map. Would anyone help me figure out how I could perform this conversion, given that I would rely on a linear interpolation method within triangles faces (the result would be close to what r.surf.nnbathy does, except nor this addon does support breaklines). Exporting a vtk file out of grass I tried to explore capabilities of other software like Paraview and MEshLab, but without results... Thank you, Vincent _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
