DIGITAL TERRAIN MODEL
STREAM builds a clean bare-earth Digital Terrain Model from ground-classified points, or opens one from GeoTIFF, and turns it into the base for volumes, cross-sections, contours and analysis.
A Digital Terrain Model (DTM) is the bare-earth surface with buildings and vegetation removed. It is the reference most engineering work needs — earthworks, drainage, contours and grading are all built on the terrain, not the objects on it.
STREAM derives a DTM from ground points and computes on it directly.
Build a clean DTM from ground-classified points of a LAS/LAZ cloud, automatically on import.
Cut/fill, cross-section cubature and stockpiles run on the bare-earth surface for correct engineering quantities.
Generate contours and run hydrology on the DTM to model the real ground shape and flow.
Already have a DTM? Open it directly from GeoTIFF and start measuring.
STREAM builds a clean bare-earth DTM from ground-classified points of a LAS/LAZ cloud on import, or opens an existing DTM from GeoTIFF.
Earthwork quantities should be measured on the bare-earth terrain, not on buildings or vegetation, so a DTM gives correct cut/fill and grading results.
Yes. STREAM generates contours at any interval directly from the DTM and exports them as editable DXF vectors.
Free beta for Windows x64. Works fully offline with GeoTIFF, LAS/LAZ and DXF.
