GeoEye-1
Ideal for large-scale mapping projects, GeoEye-1 provides highly detailed imagery at .46-meter panchromatic and 1.84-meter multispectral resolutions. It can geolocate features to less than 5m, offers stereoscopic collection on a single pass, and can revisit any point on Earth once every three days.
When we need high-resolution satellite imagery, we trust Pacgeo for their quality imagery and reliable turnaround times. ​

Ordering high-res satellite imagery through a partner agency order desk was always painful and fraught with multiple issues. Dealing directly with Pacgeo allows me to bypass the aforementioned issues, while getting quick and reliable access to the data I need.
