IKONOS Stereo Satellite Imagery
Reference stereo products have a horizontal accuracy of 25 meters CE90 and a vertical accuracy of 22 meters LE90 without any Ground Control Points (GCP’s). When reliable GPS derived GCP photo ID control is available for the area to be collected the horizontal and vertical Geospatial accuracy increases to <2.5m horizontal and <1.5m vertical.

IKONOS stereo satellite images have the potential for creating DSM/DEM's. The primary advantage of stereo imagery is the ability to extract vector features and geographic features in 3D such as buildings, roads, manmade structures and other terrain features. This accuracy can be consistently achieved with terrain slope conditions of <20%.
Stereo satellite imagery is especially important for global markets where accurate elevation data is not readily available. Many commercial markets will benefit from stereo imagery andincluding mapping for exploration, , , , , and .
The three main attributes of IKONOS stereo imagery are 360-degree pointing capability, a base-to-height (B/H) ratio of 0.6 and greater - similar in scope to aerial photography. Stereo products can be produced in either epipolar or map projection and can be acquired at most areas of the World.
Stereo products can be purchased as 11-bit or 8-bit data and are offered in the same accuracy levels as other IKONOS products.
Map projected stereo products are produced in long image strips and are recommended if block adjustment is going to be performed by the user. Long strip images facilitate block adjustment, as the user does not have to contend with small component images.

Rapid Acquisition/Rush Tasking
Rush tasking orders for satellite image data around the world are accepted in support of live events, natural disasters, global security, and various other applications in which FAST delivery of image data is critical. In most instances, we can provide image data within 24 hours after the initial data has been acquired and delivered via FTP and DVD media. A Spanish version is also available at http://www.satimagingcorp.es.
