Photogrammetry and drone surveys

What we offer

• Topographic surveys of large sites suitable for drones. Precise surveys of large areas and structures using a drone, for accurate and detailed survey data.
• Earthwork volume calculations (cut and fill) from drone surveys. Precise volume calculations based on drone data, for accurate and efficient project work.

When it beats ground surveying

For large areas, hard-to-reach terrain, quarries and stockpiles, a drone survey is faster and gives a complete picture of the terrain rather than individual points. The result is a digital terrain model from which volumes are calculated and plans are produced.

For small gardens and exact boundaries a ground survey is usually more suitable: a topographic survey with a total station or GPS. We often combine both methods.

Applications

• solar parks and large investment sites;
• quarries and stockpiles: regular volume calculations;
• construction sites: monitoring of cut and fill;
• a basis for grading plans for large areas.

What you receive

• a digital terrain model with heights;
• contour plans for design;
• volume calculations between two dates or against a design level;
• data in the cadastre's coordinate system, compatible with the other survey materials.

Limitations

Under dense vegetation and in shaded areas the drone cannot see the ground, so we supplement with ground measurements there. Flights are made in suitable weather and in line with the rules for unmanned aircraft systems. For exact property boundaries, a drone does not replace setting-out with a total station or GPS.
