Our DGPS Survey Process, Step by Step
- Site visit. We check access, vegetation and the contour interval your designer needs.
- Control points. We fix control and benchmark points so levels tie to a reliable reference.
- Field work. We take spot levels on a grid or along sections, closer together where the slope changes.
- Data processing. Points are processed into contour lines at the agreed interval.
- Drawings and report. We issue the contour map in CAD with supporting data.
