Start with qualified USGS LiDAR
TopoStudio uses USGS 3DEP QL0, QL1, or QL2 LiDAR as the foundation for existing-ground mapping. Source data is evaluated for coverage, acquisition history, quality level, and project suitability.
TOPOSTUDIO™
Bring USGS LiDAR into your survey, confidently
A practical existing-ground solution when new UAS collection doesn't make sense — transformed, scaled, and snapped to your vertical control.
Your coordinates. Your scale. Your control.
How TopoStudio works
Extend your field survey
Focus field collection on what matters — project control, independent check shots, and breakline points at critical terrain features. TopoStudio uses those observations to integrate and verify the broader terrain.
Processed with TopoPro®
The same terrain processing and QC workflow: site calibration, smart thinning, surface generation, integration of surveyed breaklines, and QC against your independent check shots.
Document your reliance
Source and QC information supports the surveyor's reliance on third-party data, clearly distinguishing surveyed observations from USGS-derived terrain and documenting every transformation and adjustment.
When a new flight doesn't make sense
Keep an undisturbed-site project moving
- Snow or weather prevents collection
- VLOS or other legal flight parameters make UAS impractical
- Blue UAS requirements drive up cost
- The budget or timeline doesn't justify a new acquisition
