Approach

Field-grade survey, processed with research-grade rigor.

Every project starts with a reference network — RTK GNSS to the national grid, photo-targets observed by total station, redundant check points. Aerial and terrestrial captures are planned around the geometry of the site, not the convenience of the equipment. Models are solved against ground control rather than RTK alone, validated on independent check points, and packaged in the formats the client's workflow actually consumes — CAD, BIM, point cloud, or streamed 3D tiles.
