Geospatial Data for Exploration & Geology

Exploration Surveying

User-ready data for resource development projects
When areas of interest are large or difficult to access, getting accurate elevation survey data can delay the progress of new resource development projects.

PhotoSat’s Exploration Surveying ensures that each project starts on a foundation of engineering-grade survey data, without the need for ground control or a site visit.

Key applications:
  • Preliminary Economic Assessment
  • Pre-feasibility and Feasibility studies
  • Resource and reserve estimates
  • Drill hole collar verification
  • Project base mapping
Elevation grid formats:
File Format(s): ASCII, CSV, DWG, DXF, ECW, ERS, LAS, TIF, and XML.

Thinned Grid formats are available to reduce file size for projects over low-grade slopes.
Technical Specifications:
Bare ground surface (DEM/DTM)
Vertical Accuracy (with control)
~10 – 30 cm RMSE More Info
Satellite Specifications for Elevation Surveys
Some specifications for survey deliverables depend on the satellite used to acquire the imagery.
