The Earth - Topographic View - Altimetric view of earth. - Bathymetric and topographic map of the Earth. Image made from radar data. The topography of the seabed was obtained from boat surveys, as well as from data obtained from ERS-1, ERS-2 and Geosat satellites. Altimetric data on the continents come from observations from the ERS-1 satellite. Color code uses: purple (- 8000m) to white (+ 3000m to+8000m); green 0 to 400 meters altitude. This global map was realized by merging a bathymetry model and the Altimetry Corrected Elevations (ACE). For the ocean, the global bathymetry was constructed by blending depth soundings collected from ships with detailed gravity anomaly information obtained from the Geosat (US Navy) and ERS - 1/2 (ESA) satellite altimetry missions. For the land elevation, database of ERS - 1 satellite altimeter were reprocessed
