Regional Topography

User-ready topography for exploration planning

When geologists are planning new exploration programs, it is crucial to have access to reliable topography of the area. But when these areas are remote or large, getting reliable topography can be difficult, potentially delaying a project at the start.

PhotoSat’s Regional Topography package equips exploration professionals with reliable topographic data, without the need for ground control or site access.
