GeoEye-1 Satellite Imagery

The GeoEye-1 satellite is equipped with some of the most advanced technology ever used in a commercial remote sensing system. The satellite collects images at .46-meter panchromatic (black-and-white) and 1.84-meter multispectral resolution. The satellite can collect up to 500,000 square kilometers of pan- sharpened multispectral imagery per day. This capability is ideal for large-scale mapping projects. GeoEye-1 can revisit any point on Earth once every three days or sooner.

GeoEye-1 Satellite Imagery

Features

  • Very high resolution

  • Industry-leading geolocation accuracy

  • High capacity over a broad range of collection types

  • Direct downlink to customer sites available

  • Frequent visits at high resolution

Benefits


  • Provides highly detailed imagery for precise map creation, change detection, and in-depth image analysis
    (Note: imagery must be re-sampled to 50 cm for non- US government customers)

  • Geolocate features to less than 5 meters to create maps in remote areas, maximizing the utility of available resources

  • Collects, stores, and downlinks
    a greater supply of frequently updated global imagery products than competitive systems

  • Stereoscopic collection on a single pass ensures image continuity and consistency of quality
