Tool Profile from Points
The tool allows one to query a profile from an input grid (usually a DEM) for point coordinates stored in a table or shapefile. The profile is traced from one point to the next, sampling the grid values along each line segment. Optionally, additional grids can be queried whose values are added to the profile table.
