Satellite Imagery
| Digital Data Services, Inc., through a partnership with GEOEYE, provides two high resolution satellite imagery solutions. These solutions, IKONOS and GeoEye-1, facilitate different specifications and applications for geospatial use.
GeoEye-1-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.
IKONOS Satellite- GeoEye first made history with the IKONOS satellite launch almost ten years ago. Imagery from both sensors on the IKONOS satellite can be merged to create 1-meter color imagery (pan-sharpened).
