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.
Features
