WorldView-3 is a commercial Earth observation satellite owned by DigitalGlobe. It was launched on August 13, 2014, to become DigitalGlobe′s sixth satellite in orbit offers 0.31 meter resolution panchromatic and eight-band multi-spectral imagery. WorldView-3 was recently licensed by the National Oceanic and Atmospheric Administration (NOAA) to collect eight-band short-wave infrared (SWIR) imagery. 12 CAVIS Bands: (desert clouds, aerosol-1, aerosol-2, aerosol-3, green, water-1, water- 2, water-3, NDVI-SWIR, cirrus, snow)
New and enhanced applications include:
- Land Classifications
- Disaster Preparedness/ Response
- Feature Extraction/Change Detection
- Soil/Vegetative Analysis
- Oil & Gas
- Mining
- Environmental Monitoring
- Bathymetry/Coastal Applications
