Topo Surveys

What is a Topo Surveys?

A Topographic (Topo) Survey is a detailed mapping process that identifies and maps the contours of the ground and existing features on, slightly above, or below the earth's surface (such as hills, ravines, trees, buildings, and utility lines). Unlike standard maps, it focuses on vertical elevation to show the 3D relief of the land.

Topo Surveys Frequently Asked Questions (FAQ)

In a world where speed, precision, and data are critical, at Geo Scan 3D we don't just scan;

What level of accuracy can I expect from a Geo Scan 3D Topo Survey?

Precision is at the core of our expertise. Depending on the project requirements and equipment used (Mobile, Aerial, or Terrestrial), we typically achieve relative accuracies in the range of 5mm to 20mm. For critical infrastructure projects, we use high-precision ground control points (GCPs) to ensure the entire dataset is perfectly tied to the required national or local coordinate system.

Can you integrate underwater topography with land-based surveys?

Our mobile laser scanning (NavVis VLX 3) achieves sub-5mm global accuracy. For even more sensitive requirements, we use control points to ensure professional-grade precision across large-scale sites.

In what formats do you deliver the final survey data?

Our mobile laser scanning (NavVis VLX 3) achieves sub-5mm global accuracy. For even more sensitive requirements, we use control points to ensure professional-grade precision across large-scale sites.

Is it necessary to close down a site or road for a Geo Scan 3D survey?

Our mobile laser scanning (NavVis VLX 3) achieves sub-5mm global accuracy. For even more sensitive requirements, we use control points to ensure professional-grade precision across large-scale sites.
