Digital elevation models and mapping



Digital Elevation Models (DEM)

Right: stereoscopic view obtained combining JERS-1 and ERS-2 SAR data acquired over north-eastern Honduras (Central America).
Left: Digital Elevation Model obtained using this stereosopic JERS-1/ERS-2 pair.
The original version of this DEM has a spatial resolution of 20 meters.


Radar clinometric DEM (ERS), Israël & Jordan 2002 Photogrammetric DEM and 3D-view (SPOT & LANDSAT), Mongolia 2003 Similarly, we produce Digital Elevation Models:

To produce Digital Elevation Models, we master also Radar-Interferometry and Radar-Clinometry techniques.


Mapping (space-maps)

UTM (Universal Transverse Mercator) map of north-eastern Honduras and northernmost Nicaragua (Central America), produced using two ERS-2 SAR images.

Similarly, we produce ortho-rectified space-maps at a spatial resolution ranging from 1 meter to 500 meters using satellite imagery obtained through sensors:

A large choice of cartographic projection types, as well as 81 different Earth ellipsoids and 428 datum's, are currently available.
