Digital Elevation Models (DEM's) provide extremely useful information for mineral exploration and other purposes.

Global Ore Discovery can produce high-resolution (<1m) DEM's and line contours derived from ASTER, IKONOS, QuickBird and other satellite images. These DEM's are spatially accurate, orthorectified 3D representations and are often the only way to analyse the topography of remote areas.

• QuickBird (down to .65m pixels)
• IKONOS (down to 1m pixels)
• ASTER (15m pixels)
• Hyperion
• Hymap
• TM

Coarser DEM's can also be derived from geophysical surveys, the SRTM mission, government agencies and elsewhere.

A new type of ASTER product is avalible, the on Demand Digital Elevation Model & Registered Radiance at the Sensor - Orthorectified
See ASTER page for more info
