Digital Elevation Models
Left: Stereoscopic View obtained combining JERS-1 and ERS-2 SAR data acquired over
North-Eastern Honduras (Central America).
Right: 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.
Similarly, we produce Digital Elevation Models:
- by Radargrammetry, using RADARSAT, ENVISAT or ALOS bi-incidence, or
ERS/RADARSAT, ERS/ENVISAT, ERS/ALOS, JERS-1/ENVISAT, JERS-1/RADARSAT, JERS-1/ALOS, RADARSAT/ENVISAT,
RADARSAT/ALOS, ALOS/ENVISAT stereoscopic pairs of satellite images,
- by Photogrammetry, using SPOT, ASTER, JERS-1 OPS bi-incidence, or
LANDSAT-TM/LANDSAT-ETM+, LANDSAT/SPOT, ASTER/SPOT, etc. stereoscopic pairs of satellite images.
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:
- Radar (SAR) : ERS, ENVISAT, JERS-1, ALOS, RADARSAT, X-SAR, or
- Optical : IKONOS, ORBVIEW, IRS, SPOT, LANDSAT, TERRA-ASTER, TERRA/AQUA-MODIS, MOS, RESURS, etc.
A large choice of cartographic projection types, as well as 81 different Earth ellipsoids
and 428 datum's, are currently available.
