Then drape the relief map over the smoothed digital elevation modelĪlternatively try visualizing relief using diffuse illuminationįrom the skyview factor - the proportion of the sky visibleĪ composite of the shaded relief and skyview factor ![]() The light source can be set using the altitude and azimuth settings. Visualize the relief of the terrain using direct illumination with Optionally make the moving window circular with flag -c. Smooth the digital elevation model using the module Has substantial noise that would impact hydrological simulations. Then set a mask to the vector map shoreline with the module Using the various zoom options dropdown orĪnd set the boundaries for the region. Zoom in on the landforms in the southwest of the island.Įither set the computation region from the display Select nyspf_governors_island as your location,Īnd create a new mapset called hydrology.
