Survey data
you can build from

Snelgrove Survey Ltd flies photogrammetry and LiDAR missions over live groundworks, residential plots and infrastructure corridors — then returns measured, checked, CAD-ready data. From pre-planning topography to time-stamped progress evidence, every deliverable is traceable back to surveyed control.
