WorldView – 2

Digital Globe’s WorldView-2 satellite sensor, launched October 8, 2009, imaging in 0.46m panchromatic mono and stereo satellite image data. It was the first satellite from Digital Globe flock, which provided imagery in 8 spectral bands with resolution less than 2 m. Sensor is imaging around 2 million sq km daily, and it’s time interval is 1,1 day. Orbit altitude is 770 km. Data provided by the system are very accurate and are widely used for land cover change detection.
