On November 11th, DigitalGlobe successfully launched its latest satellite, WorldView-4, into space from Vanderberg Air Force Base in California. WorldView-4 will join its existing sister satellite, WorldView-3, in imaging 680,000 square kilometers (sq km) of data at 31-centimeter (cm) panchromatic and 1.24-meter (m) multispectral resolution per day.
Apollo Mapping is excited to see another DigitalGlobe satellite launch, doubling our 30-cm collection capacity. DigitalGlobe calibrates its satellites faster than anyone else in the industry so we expect WorldView-4 will be ready to go by Q1 2017!
