wORLDVIEW-3
WorldView-3 was launched on August 13 2014, and truly set a new standard for commercial satellites in-orbit. With 29 spectral sensors on-board, the data from WorldView-3 allows you to differentiate between objects with far greater accuracy. Additionally, WorldView-3 was the first satellite capable of delivering true 31 cm resolution and collects the industry’s best very high resolution imagery quickly and reliably.
