Digital Data Services, Inc., through a partnership with GEOEYE, provides low resolution satellite imagery and two high resolution imagery solutions. These three solutions, OrbView-2, IKONOS and GeoEye-1, all facilitate different specifications and applications for geospatial use. OrbView-2 provides a resolution of 1.1 kilometers per pixel, and the primary applications are in the agriculture and offshore fishing industries. The imaging channels are six visible and two near infrared bands.

IKONOS on the other hand shares similar specifications and is useful for many of the applications that the recently launched GeoEye-1 does. IKONOS’s resolution is sampled to .82 meters per pixel. The offered deliverables are pan-sharpened (natural color), panchromatic (grayscale) and near infrared bands. GeoEye-1 is now the highest resolution commercial satellite that orbits the earth at .4 meters per pixel. However, it is sampled to half a meter to meet NOAA, NIMA and CIA regulations. The following overlapping applications for these two satellites are most often utilized as a geospatial solution for national security, government, natural resources, oil and gas, alternative energy, mining and exploration, utilities, internet mapping, infrastructure management, insurance, emergency preparedness, real estate, visual simulation, and transportation.

GEOEYE Satellite Imagery

The GeoEye-1 satellite is equipped with the most advanced technology ever used in a commercial remote sensing system. The satellite collects images at 0.41-meter panchromatic (black & white) and 1.65-meter multispectral resolution. Just as important, the accuracy of GeoEye-1 is predicted to be within 3 meters of its true location on the surface of the Earth. This degree of inherent geolocation accuracy has never been achieved in any commercial imaging system.

The satellite collects up to 700,000 square kilometers of panchromatic (and up to 350,000 square kilometers of pan-sharpened multispectral) imagery per day. This capability is ideal for large scale mapping projects. GeoEye-1 will be able to revisit any point on Earth once every three days or sooner.

  GEOEYE-1 and IKONOS Feature Comparison

IKONOS SATELLITE IMAGERY-

GEOEYE Satellite Imagery

GeoEye categorizes IKONOS imagery products according to positional accuracy, which is determined by the reliability of an object in the image to be within the specified accuracy of the actual location on the ground.
 
Within each product, location error is defined by a circular error at 90% confidence (CE90), which means that locations of objects are represented on the image within the stated accuracy 90% of the time. The CE90 accuracy scale can be related to Root Mean Square Error (RMSE) as well as the U.S. National Map Accuracy Standards (NMAS).
 
All Geo products are map projected—rectified to a datum and map projection system. GeoEye removes image distortions, and resamples the imagery to a uniform Ground Sample Distance (GSD) and a specified map projection. Because Geo images are not orthorectified, their accuracy is limited by terrain displacement.
