Aerial Topography Surveys for Enhanced Ground Data

Capture topographic elevation and surface behavior for planning, design, build, or verification.

Elevation Modeling you can take to the Bank

FAST captures terrain behavior and elevation variation using aerial mapping verified to control and set in local datums—ideal for layout, quantity, drainage, or grading visibility.

No Interruption, Full Context

We collect topographic data via drone and verify with 6-20 ground control points—no ground crews needed in active or sensitive areas.

Elevation Reference from Image Capture

Our aerial survey process models sites via point cloud and converts them into structured elevation data and digital twins—suitable for planning projects, designing drainage and work sequence, viewing grade progress, calculating fill, and verifying quantities moved on sites.

FAQs About Topographic Surveys

We answer common questions about accuracy, file types, and site requirements.

What accuracy do your drone topo surveys provide?

With RTK/PPK and ground control, vertical accuracy is typically within 3–5 cm RMSE—suitable for grading, drainage, and design plans.

How is elevation data structured for use in planning tools?

Contours and elevation data are structured to support grading, drainage, and layout planning. All references are geo-aligned and compatible with GIS and civil workflows.

Are these surveys suitable for formal planning or compliance use?

Yes. Our process supports technical planning and civil workflows. PSM review and sign-off are available when required for regulatory compliance.
