Satellite Elevation Data

Map and monitor topography with comprehensive elevation data options

Our comprehensive knowledge provides you with the best satellite elevation data and processing options for topographic mapping, surveying, and monitoring of your projects and operations. We create and supply digital elevation models (DEMs) at a range of resolutions from a variety of sources.

Custom Elevation Data

We generate industry-leading high-resolution elevation models from stereo and tri-stereo optical satellite imagery on a custom basis. With vertical accuracies of up to 10 cm to 15 cm at spatial resolutions of up to 1 m, our expert processing generates topographic survey data suitable for diverse and demanding applications, spanning onshore oil fields, mine sites, engineering, site characterization and geohazards.
