Tool ANGMAP


This tool computes the acute angle raster between the topographic surface defined by slope and aspect rasters internally derived from input elevation raster, and a structural plane defined by diop direction- and dip grids. Optionally, the dip direction and dip of the cutting line linears between the two planes can be calculated
