GIS
STREAM is desktop GIS software for terrain, brought into one fast app. Layer georeferenced DEMs, orthophotos, point clouds and vectors in true position, analyze the surface, and export results to the formats your GIS and CAD tools expect — all offline.
A GIS ties spatial data to real-world coordinates so you can view, measure and analyze it together. STREAM applies that to elevation and imagery: it reads each layer's coordinate reference system, stacks DEMs, orthophotos and vectors correctly, and derives new information from the surface.
It isn't a general-purpose GIS for every dataset — it's a terrain-first GIS that turns elevation into slope, flow, visibility, volumes and clean vector output.
Load DEMs, orthophotos, point clouds and DXF and STREAM aligns them by their CRS — no manual placement.
Slope, aspect, viewshed, line-of-sight, hydrology, contours and sun & shadow, shown as live overlays.
Draw points, lines and areas on the terrain, organize them in layers, and triangulate surfaces.
Export analysis as GeoTIFF rasters and vectors as DXF/CSV, with georeferencing preserved.
Load DEMs, orthophotos and point clouds straight from GeoTIFF and LAS/LAZ — the formats your GIS already produces.
The CRS is read from each file and shown for confirmation, so the data lands where your GIS expects it.
Volumes, cross-sections, contours, slope, hydrology and viewshed run at full raster resolution on the desktop, with no upload step.
Analysis rasters go back as GeoTIFF and vectors as DXF or CSV, with georeferencing preserved.
The source files are never modified — STREAM references them and keeps its own fast cache, so the same data stays usable in both tools.
STREAM is a terrain-focused desktop GIS: it reads georeferenced DEMs, orthophotos and vectors, runs terrain analysis on them, and exports GIS-ready GeoTIFF and DXF — offline.
Yes. STREAM reads each layer's CRS so data aligns correctly, and preserves georeferencing on export.
Slope, aspect, viewshed, line-of-sight, hydrology, contours, sun & shadow and change detection — plus volumes and cross-sections.
Free beta for Windows x64. Works fully offline with GeoTIFF, LAS/LAZ and DXF.
