WorldView-3

WorldView-3 is the industry’s first multi-payload, super-spectral, high-resolution commercial satellite. Operating at an altitude of 617 km, WorldView-3 provides 31 cm panchromatic resolution, 1.24 m multispectral resolution, 3.7 m short-wave infrared resolution, and 30 m CAVIS resolution. WorldView-3 has an average revisit time of less than one day and is capable of collecting up to 680,000 sq km per day, further enhancing the Maxar collection capacity for more rapid and reliable collection.

SPOT-6/7

The SPOT twins operate in phased orbits and can revisit any point on the globe once per day. They deliver 1.5-meter high-resolution imagery across five spectral bands and can capture 6 million square kilometers per satellite per day.

MAXAR

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.
