Seismic Receiver Point Elevations from Satellite Survey

DEM sources receivers

Replace GPS receiver point surveying

For onshore seismic surveys using autonomous geophone recording systems such as the Geospace GSX, 20cm accuracy PhotoSat satellite surveying can be used for the receiver point elevations instead of conventional GPS surveying. This can result in significant project cost savings and eliminate the HSE risk associated with land survey teams.

Eliminate the field risks and costs associated with conventional seismic receiver point surveying

Eliminate the field risks and costs associated with conventional seismic receiver point surveying.

Satellite surveys for seismic receiver points:

  • Improves seismic quality
  • Reduces the need for ground surveying
  • Provides necessary source and receiver elevation accuracy for seismic processing

Improve seismic receiver point elevations

Reduce surveyor field days

Seismic geophone with GPS location recording. Usually accurate to 2m horizontal and 3m in elevation.

Seismic geophone with GPS location recording. Usually accurate to 2m horizontal and 3m in elevation.

Using our engineering quality survey data, the GPS surveying of autonomous geophone locations can be eliminated; reducing costs and the HSE risks associated with field survey teams. The autonomous geophones typically record their locations with a horizontal accuracy of 2m and vertical accuracy of 3m. By combining the recorded geophone horizontal locations with the PhotoSat elevations, the GPS surveying of the seismic receiver points has been completely eliminated on a number of seismic projects.

Improve seismic quality

seismic receiver point errors

The 50cm horizontal and 20cm vertical accuracy of our satellite survey provides the necessary source and receiver location elevation accuracy for seismic processing. Surveying blunders at shot and receiver locations, usually caused by the loss of GPS signals, are readily detected and corrected using PhotoSat’s satellite survey. In some situations this can substantially improve the quality of the seismic processing of shallower horizons.

PhotoSat’s satellite surveying

PhotoSat has invented new algorithms to satellite surveying with accuracy better than 20cm. We have completed over 900 projects globally.

Our satellite surveying package includes a 1m elevation grid accurate to better than 30cm, 50cm or 1m contours, and a 50cm precision satellite orthophoto.

Proof of accuracy

The accuracy of PhotoSat’s satellite surveying has been proven using tens of thousands of ground survey points for comparison. View our Proof of Accuracy Reports
