GIS & REMOTE SENSING
A Satellite is an object in space that orbits or circles around a bigger object. There are two types of satellites: i) Natural; such as the Moon and Earth, and ii) Artificial; such as the Landsat, SPOT, IRS, Quickbard, Aster.
IKONOS Satellite IKONOS Satellite was launched in September 1999. IKONOS panchromatic Sensor resolution is 1 m, and multispectral scanner resolution is 4 m. The swath width is 13 km at nadir. Accuracy with out ground control is 12 m horizontally, and 10 m vertically; with ground control it is 2 m horizontally, and 3 m […]
QuickBird Satellite QuickBird Satellite was launched in 2001, by Digital Globe offering imagery for map publishing, land and asset management, change detection and insurance risk assessment. The QuickBird produces sub-meter resolution Panchromatic and Multispectral imagery. The data collection nominal swath width is 16.5 km at nadir, and areas of interest sizes are 16.5 km x
