How with an MNT image it is possible to find flow directions? Or would there be another way to do it? Thank you
I'm not familiar with an MNT image, so this approach may not apply. Typically, flow directions can be found by using raster analysis on a Digital Elevation Model (DEM) via the Spatial Analyst Extension. In the Spatial Analyst toolbox, they have several tools, one of which is Flow Direction.
