POINT CLOUD
STREAM opens large LAS and LAZ point clouds and turns them into usable terrain. Build a bare-earth model from ground points, a surface model from all points, or an orthophoto — then measure and analyze the result like any DEM.
A point cloud is a dense set of 3D points (x, y, z) captured by LiDAR or produced by photogrammetry. LAS is the standard format; LAZ is its compressed form.
Point clouds are rich but heavy. To get engineering results you usually need to turn them into a surface — a DEM or a mesh — which is exactly what STREAM does on import.
Load large LAS and LAZ files with class information; STREAM streams them efficiently instead of choking on the point count.
Build a clean bare-earth DEM from ground-classified points, a surface model from all points, or an orthophoto — automatically on import.
Sample the cloud onto a regular grid at the resolution you choose to get a clean, analyzable elevation raster.
Once rasterized, run volumes, cross-sections, stockpiles, slope and hydrology on the point-cloud-derived surface.
Yes. STREAM opens both LAS and LAZ point clouds and can rasterize them into a DEM or surface model at the resolution you choose.
Yes. STREAM builds a clean terrain model from ground-classified points, a surface model from all points, or an orthophoto — automatically on import.
STREAM is designed for large clouds; it streams the data and converts it to a fast internal format so it stays responsive on big datasets.
Free beta for Windows x64. Works fully offline with GeoTIFF, LAS/LAZ and DXF.
