WorldView-4 Satellite Sensor (0.31m)
WorldView-4 satellite sensor was successfully launched on Friday, November 11, 2016 at 10:30 a.m. PST from Vandenberg Air Force Base, California. DigitalGlobe's WorldView-4 satellite is capable of discerning objects on the Earth's surface as small as 31cm in the panchromatic and will collect 4-band multispectral at 1.24-meter resolution. WorldView-4 will have similar resolution as the WorldView-3 satellite sensor. This advanced resolution will offer customers unprecedented, precise views for 2D or 3D mapping, change detection and image analysis.

Watch WorldVIew-4 Satellite Launch
WorldView-4 will offer exceptional geolocation accuracy, which means that customers will be able to map natural and man-made features to better than <4 meter CE90 of their actual location on the Earth’s surface without ground control points.
WorldView-4 will be flying at an altitude of 617 km (383 miles) and will be able to “revisit” any point on the globe every 4.5 days or sooner, depending upon the required look angle. The altitude could be revised before launch to utilize the recently obtained permission to acquire and deliver 0.25m resolution Imagary.
WorldView-4 customers will have a choice of ordering BASIC (satellite projection), Geo (geometrically corrected), GeoProfessional (terrain corrected or ortho-rectified), or GeoStereo (stereo pair) products, as well as imagery-derived products, including Digital Elevation Models (DEMs), Digital Surface Models (DSMs), large-area mosaics and feature maps.

Resolution restrictions have been relaxed
During June 2014 DigitalGlobe received permission from the US Department of Commerce to collect and sell imagery at the best available resolutions. Additionally, six months after WorldView-3 is operational DigitalGlobe will be permitted to sell imagery at up to 25 cm panchromatic and 1.0 m multispectral GSD. We applaud the US Government’s relaxation of satellite resolution restrictions, as it benefits our customers, and the industry in general.

Satellites Currently Operated by DigitalGlobe
Rush tasking orders for satellite image data around the world are accepted in support of live events, natural disasters, global security, and various other applications in which FAST delivery of image data is critical. In most instances, we can provide image data within 24 hours after the initial data has been acquired and delivered via FTP and DVD media. A Spanish version is also available at http://www.satimagingcorp.es.
