The WorldView-4Â Advantage
A Twin in Space
WorldView-3 and WorldView-4 both offer(ed) 31-cm resolution making them the perfect tandem for the highest resolution data possible over your area of interest.
Huge Collection Capacity
Matching the capacity of WorldView-3, this satellite tandem collected more than 480 million sq km each year, or about three times the area of the entire world’s land mass.
Overview & History
After two years in space alone, WorldView-4 joined its high-resolution satellite twin, WorldView-3, as the only 31-centimeter (cm) optical sensors in orbit. Also launched by Maxar Technologies from Vandenberg Air Force Base in California, WorldView-4 reached orbit on November 11, 2016 offering 31-cm panchromatic and 1.24-meter (m) four band (i.e. blue, green, red and near-infrared) multispectral. As WorldView-4 started its life as GeoEye-2, it is not identical to WorldView-3 but was significantly upgraded to match its twin as close as possible.
If your project demands the world’s highest resolution satellite imagery, then the tandem of WordlView-3 and WorldView-4 should be your next imagery choice!
As of early 2019, WorldView-4 is in non-recoverable status and no longer collecting new imagery.
