SURFACE ANALYSIS
STREAM turns your DEM into clear slope and aspect maps. See surface steepness on a color scale, find which way slopes face, and save the result as a live overlay, a raster or a vector layer.
Slope measures how steep the terrain is at each point; aspect measures the direction a slope faces. Both are derived from the DEM and are fundamental inputs for siting, drainage, agriculture and hazard work.
Viewing them as a color layer over the terrain makes patterns obvious that raw elevation hides.
Visualize steepness across the whole DEM on a color scale, as a live overlay on the terrain.
See which direction each slope faces, isolate specific directions, and read it on a compass legend.
Alongside slope and aspect, run viewshed, line-of-sight, hydrology, contours and sun & shadow on the same DEM.
Keep results as a live overlay or export them as raster (GeoTIFF) or vector.
Yes. Slope and aspect are computed directly from the DEM surface and shown as a color overlay on the terrain.
Yes. Results can be kept as a live overlay or exported as raster (GeoTIFF) or vector layers.
Viewshed, line-of-sight, hydrology, contour generation, sun & shadow and change detection — all on the same DEM.
