ORTHOPHOTO
STREAM streams large orthophotos straight from GeoTIFF and drapes them over your terrain. Use the imagery as a precise basemap to measure, digitize vectors and read the site alongside the elevation surface — no waiting, no cloud.
An orthophoto (orthomosaic) is an aerial image that has been geometrically corrected so every point is shown as if viewed straight down. Because the scale is uniform, you can measure real distances and areas directly on it.
Orthophotos pair naturally with a DEM: the DEM gives elevation, the orthophoto gives visual context. STREAM shows both together.
Open gigabyte-scale GeoTIFF orthophotos; only the visible area loads in full detail, so huge mosaics stay responsive.
Overlay the orthophoto on your DEM in 2D and 3D to read imagery and elevation together.
Use the imagery as a precise backdrop to measure and draw vector points, lines and areas that snap to the terrain.
STREAM can also produce an orthophoto from a photogrammetry point cloud on import.
Yes. STREAM streams gigabyte-scale GeoTIFF orthophotos out-of-core, loading only what you are looking at, so large mosaics stay responsive.
Yes. Because the imagery is georeferenced and draped on the DEM, you can measure real distances and areas and digitize vectors directly on it.
STREAM does not process raw photos — that is photogrammetry. It opens finished orthophotos, and can generate one from a photogrammetry point cloud.
Free beta for Windows x64. Works fully offline with GeoTIFF, LAS/LAZ and DXF.
