Hi PH 👋 I'm Mehmet, and I built STREAM. The problem: survey data got huge. A single site DEM, orthophoto or LiDAR point cloud can be several gigabytes. Most desktop tools either choke on it or push you to the cloud — and a lot of engineers simply can't send client data to a server. STREAM streams that data out-of-core and renders it on the GPU (Vulkan), so a multi-gigabyte survey opens immediately and stays smooth while you pan and measure. From there it gives you the deliverables engineers actually hand over: • Cut/fill volumes against real terrain, a flat design level or another surface • Cross-section cubature with a station-by-station table and DXF drawings • Stockpile volume and tonnage with a print-ready PDF report • Contours, slope/aspect, viewshed, hydrology, sun & shadow • Change detection between two surveys, with volume ± uncertainty Everything runs locally — no account needed to process, no upload, works with no internet. Imports GeoTIFF, LAS/LAZ and DXF; exports DXF, CSV, GeoTIFF and PDF. It's a free public beta for Windows 10/11 (x64) — all features unlocked, no time limit, no watermark. The app and site are in 6 languages. I'd love feedback from surveyors, drone operators, earthworks and mining teams: what's the one measurement that still eats your time?
