Who builds STREAM?

Graduate of Geomatics (Surveying) Engineering at Cumhuriyet University. Since 2016 he has worked as a chief surveyor on mining, dam and infrastructure projects, and still holds that role at a mining company.

His day-to-day work is monthly production volumes, stockpile measurement, pit and haul-road layout, cut and fill analysis, and the reporting that goes with them. STREAM was written for exactly this work — first for his own use, then for the people doing the same job.

He holds a commercial UAV pilot licence and a MAPEG Authorized Technical Personnel certificate, and works with drone- and LiDAR-derived DEMs, orthophotos and point clouds on his own projects every week.

Drone and LiDAR data kept growing every year, but the workflow in the field stayed the same: wait for the DEM, orthophoto and point cloud from your photogrammetry software to open, switch to another program for volumes, another for cross-sections, then assemble the report by hand. Every hand-off risks a shifted coordinate system and a simplified surface.

STREAM was written to close the middle of that chain. It does not replace photogrammetry software — it takes its output. Open the DEM, orthophoto and LAS/LAZ files you produced in Pix4D, Agisoft Metashape or DJI Terra and turn them into engineering deliverables: volumes, quantity tables, cross-sections, analyses, drawings and reports.

Most design decisions come from the field. Stating in the report which reference a volume was computed against, making sure the section interval does not degrade the surface resolution, keeping data off the cloud — these exist because they are real problems in this work, not to lengthen a feature list.
