I have surveyed cross sections of the bathymetry of a creek. The data is in the form of points. I have a hold of a tool that will create a DEM of the creek bathymetry, but the input it needs for the cross section data is 3d polylines. I cannot find a tool that will allow me to create 3D polylines from my point data. Help please!
Or, does anybody know of a good way to create a DEM of the creek bathymetry straight from the points?
