What is a Digital
Elevation Model ?

Digital Elevation Models
(DEMs) provide a unique description of our environment
in 3 dimensions. A DEM file
is a simple, regularly spaced grid of elevation points over a topographic surface.

Elevation data

PlanetObserver presents a new Digital Elevation Model (DEM), entirely reprocessed and offering a global coverage, with a 90m resolution, that gives you highly detailed information on the environment.

Combined with PlanetObserver satellite images, this reference terrain dataset is best adapted to create high quality 3D views, perfect for all simulation and geolocation solutions.

News NEW : DEM of the Alps at 30m now available !

puce titre h2 90m Digital Elevation Model

PlanetObserver 90m DEM is derived from SRTM dataset (Shuttle Radar Topography Mission), version 4.1, combined with other source data (GDEM Global Digital Elevation Model, cartographic data, etc.). 

90m DEM

The above map shows, in dark colour, SRTM data coverage, and in light colour, corrected data that have been added beyond 56° North latitude and 60° South latitude, and in many other relief areas (Alps, Himalayas, Andes, etc.) in order to offer global reliable information.

PlanetObserver has compiled and extensively reprocessed those data in order to offer a comprehensive global DEM with precise, corrected and detailed information for the entire Earth. 

  • All emerged land covered (at 99%).
  • WGS84 projection available off-the-shelf ; others on demand.
  • Delivery format : GEOTIFF 16 bits ; other formats on demand (DTED1, etc.)
DEM 90m

Perfect for simulation and visualisation solutions

This elevation dataset, available exclusively fromPlanetObserver, is the quality solution for many 3D projects and solutions :

  • 3D visualisation & simulation solutions (Eurocopter, etc.),
  • geological survey (BRGM, etc.),
  • moving map applications (Xample, etc.),
  • content production tools for broadcast and weather industry (Vizrt, Ask, Meteo France, etc.) ...

Product Benefits

  • Data extensively corrected, in particular on all relief areas and in many other parts of the world (US, Canada, Africa such as Mauritania, etc.).
  • Comprehensive product, for your most demanding projects.
  • Terrain data available as a stand-alone product, or combined with our satellite images.
