Quality guaranteed
- Derived directly from the Reference3D database produced for French defence users, SPOT DEM Precision is designed to very strict specifications, assuring zones of uniform geometric quality and guaranteeing the DTED2 specifications.

Designed to meet military requirements, SPOT DEM Precision gives quality and traceability indicators for each pixel:
  • absolute horizontal and vertical accuracy,
  • source data,
  • production processes,
  • all corrections and checks.
SPOT Precision DEM is the only DEM to provide detailed information on the identification and location of the kind of residual errors (gaps, artefacts, etc.) found in all DEMS generated by automatic correlation.
