WorldView Legion
Maxar’s Next-Generation Earth Imaging Satellites: WorldView Legion
Maxar Technologies, a leading provider of Earth imagery and intelligence, is set to revolutionize the satellite imaging industry with its next generation of Earth imaging satellites – WorldView Legion. This constellation of satellites will be comprised of six 30cm resolution satellites designed to provide organizations with highly accurate and up-to-date satellite imagery. The ability of WorldView Legion to revisit a target area up to 15 times per day will provide organizations with near real-time information that is crucial to making informed decisions. And with the capacity to collect an astonishing 5 million square kilometers per day of satellite imagery, organizations will have a comprehensive view of the Earth like never before. Whether it is monitoring crops and wildlife, predicting natural disasters, or tracking the impact of human activities, WorldView Legion will provide organizations with the information they need to move forward with confidence.

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.
