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.

Satellite Specifications for Elevation Surveys

Some specifications for survey deliverables depend on the satellite used to acquire the imagery.
