GEOTIFF
STREAM is GeoTIFF software built the way surveyors need it: gigabyte DEMs and orthophotos stream smoothly, the embedded georeferencing places them correctly, and you can measure, analyze and export straight from the raster.
GeoTIFF is a standard TIFF image with embedded georeferencing — a coordinate system, origin and pixel size — so every pixel maps to a real location. It is the everyday format for DEMs (single-band elevation) and orthophotos (colour).
Because the georeferencing lives in the file, a GeoTIFF drops onto the correct spot and overlays perfectly with other layers in the same system.
Open gigabyte-scale GeoTIFF rasters out-of-core; only the visible area loads in full detail.
Read GeoTIFF as an elevation DEM or a colour orthophoto, and overlay them together on the terrain.
STREAM reads the embedded coordinate reference system so layers land in the right place automatically.
Save analysis results, cut/fill maps and cropped rasters back out as GeoTIFF for GIS and CAD.
Select the GeoTIFF; STREAM detects whether it is an elevation raster or imagery and streams it out-of-core instead of loading it whole.
The CRS embedded in the file is shown for confirmation before the layer joins the project.
The first load writes a fast internal cache next to the source, which is why the second open takes seconds.
Measure, analyse and compute volumes directly on the raster — nothing is resampled down for display.
Save analysis results, cut/fill maps or a cropped extent as a georeferenced GeoTIFF for GIS and CAD.
Yes. STREAM streams gigabyte-scale GeoTIFF DEMs and orthophotos out-of-core, loading only what you are viewing, so large rasters stay responsive.
Yes. STREAM reads the embedded CRS so GeoTIFF layers are placed correctly and overlay with other data.
Yes. Analysis results, cut/fill heat maps and cropped rasters can be exported as GeoTIFF.
Free beta for Windows x64. Works fully offline with GeoTIFF, LAS/LAZ and DXF.
