1m Survey (DEM) for Texas Oil & Gas

PhotoSat provides off-the-shelf digital elevation grids (DEMs) for parts of the major oil producing regions of Texas. For other areas in Texas, we offer on-demand elevation data that we can produce using existing satellite imagery in a few days. Contact us at info@photosat.ca with your project area and we will provide details, or visit our online store to order right away.

The vertical accuracy of PhotoSat’s 1m elevation grids in Texas is better than 1m, making the data suitable for engineering and precision GIS tasks. The satellite survey is bare earth (DTM) with man-made features and vegetation removed, making the data ideal for construction and development planning. These elevation grids are used by our oil and gas clients for:

  • Reducing the need for ground surveyors
  • Well site and well pad design
  • Pipeline route, powerline, and road planning
  • Seismic planning
  • Slope analysis
  • Environmental assessment and planning

For even higher accuracy, we offer a 20cm accuracy surveying package anywhere in the world.
