Surveying for Mining & Development

Development Surveying

User-ready data for project design and planning

Effectively and efficiently managing major infrastructure projects comes with a host of challenges. For engineers, it is crucial to obtain engineering-grade survey data that covers the entire project area, without interfering with ground activity.

PhotoSat’s Development Surveying gives engineers accurate and site-wide data, so projects can continue as planned.

Key applications:

Mining development and expansion
Preliminary construction projects
Renewable energy projects (e.g. wind farms)

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.
