Independent research methodology
Our researchers use a mix of verified reviews, independent research, and objective methodologies to bring you selection and ranking information you can trust.

STREAM overview
What is STREAM?
STREAM is a Windows application for offline terrain modeling and geospatial analysis, built for engineers, surveyors, and earthworks teams working with large-scale spatial datasets.
Core data handling: STREAM ingests LAS/LAZ point clouds, digital elevation models, orthophotos, and CAD drawings (DXF), converting point clouds into terrain or surface models. Intelligent data streaming keeps navigation smooth even with gigabyte-scale datasets, without requiring the full dataset to load into memory upfront.
Measurement & volumetrics: Built-in tools calculate distances, elevation differences, areas, and volumes. Stockpile analysis computes material volume and tonnage from configurable reference planes and density settings.
Terrain analysis: Slope visualization, aspect mapping, viewshed and line-of-sight analysis, hydrogeological flow modeling, contour generation, and sun-shadow/solar analysis. Change detection automatically identifies cut and fill areas between terrain states.
Interoperability: Import/export in DXF, CSV, GeoTIFF, PDF, and common vector formats, supporting integration with existing CAD and GIS pipelines.
Platform: Runs fully offline on Windows with GPU-accelerated rendering, project management tools, configurable units, multilingual UI, and light/dark themes — no cloud dependency or continuous internet connection required.
