Rounding out the GEO Elevation product family, Elevation4 and Elevation1 are high-resolution DEMs. Elevation1, with a posting of 1 metre, is ideal for hydrology and oil or mineral exploration applications, while Elevation4, with a posting of 4 metres, is more suited to 3D mapping of dense urban areas or relief in steep terrain.
Elevation4 and Elevation1 are compliant to HRE40 and HRE10 standards (comparable to DTED levels 3 and 4).
These 3D models include bare-earth and surface features (man-made structures and vegetation). They are delivered with the stereo or tristereo source data and for Elevation1 with a 50-cm orthoimage.
