GeoWEPP - Step 1: Import of DEM and Area of Interest

The first step in the wizard allows the import of Digital Elevation Models by downloading and importing interactively USGS datasets. This procedure also enables the user to automatically merge adjacent DEM quad sheets. The next wizard screen allows interactively to download a digital topographical map (called Digital Raster Graph). The image will be used as an transparent overlay for the DEM imported in the previous step which allows the user to locate the area of interest.
