TERRAIN ANALYSIS
STREAM doesn't just show the terrain — it makes sense of it. Run a full suite of analyses directly on your DEM, view the results as a live color layer over the surface, and save them as raster or vector whenever you want.
Terrain analysis derives meaningful information from an elevation surface — steepness, flow, visibility, sun exposure and change over time. Each analysis reads the DEM and produces a new layer you can interpret and export.
Doing it in one offline desktop app keeps sensitive project data on your machine and the whole workflow fast.
Surface steepness and slope direction as color overlays, with direction isolation and a compass legend.
See what is visible from a point, and whether an obstacle blocks the line between two points.
Water flow, drainage and watershed analysis, plus contour generation at any interval.
Sunlight-hours with topographic shadow, and volume change with uncertainty between two surveys.
Slope, aspect, viewshed, line-of-sight, hydrology, contour generation, sun & shadow, and change detection — all computed on the DEM.
Yes. Analysis results appear as a live color layer over the terrain, and can be saved as raster or vector.
Yes. All analysis runs locally on your computer; your data never leaves your machine.
Free beta for Windows x64. Works fully offline with GeoTIFF, LAS/LAZ and DXF.
