Sydney LULC using WorldView 2,atmospherically compensated 8-band imagery

An improved algorithm for fully unsupervised Land-Use Land-Cover (LULC) generation using atmospherically compensated 8-band imagery from the WV2=< series. The method identifies natural elements only, i.e. vegetation, cloud, water, soil, shadows, etc.

WorldView-4 launch seen from space.

To celebrate the beginning of orbital operations for Worldview-4, DigitalGlobe has released this incredible photograph of the satellite launching into space from Vandenberg Air Force Base taken from space.

The company’s WorldView-2 satellite was flying 396 miles northeast the California launch base, or roughly central Nevada, when the launch occurred November 11. 

An Atlas V rocket is seen just above Space Launch Complex 3E, having lifted off the pad moments earlier. Many of the complex’s structures can be seen, including outlying support facilities. The launch mount is seen below the rocket’s flame with the Fixed Umbilical Tower immediately to its right. The 239-foot Vertical Integration Facility is seen surrounded by three exhaust plumes coming out of the complex’s exhaust ducts.

Launched in 2009, WorldView-2 has a color resolution of six feet, while the WorldView-4 satellite has a color resolution of four feet and a black and white resolution of one foot. DIgitalGlobe also released an image of Subi Reef in the South China Sea to show off the new satellite’s abilities.
