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.
Summary: – Synthetic Aperture Radar (SAR) is an active remote sensing technology that uses microwave radar signals to create high-resolution images of the Earth’s surface, regardless of weather conditions or daylight. What is Synthetic Aperture Radar? A Synthetic Aperture Radar (SAR) is an airborne or spaceborne side looking Radar system which utilizes the flight path […]
Remote Sensing Satellite Remote Sensing (RS) technology based on Satellites system. This technology began with the early use of Aerial Photography, then it’s shifted satellites. These satellites orbit the Earth and capture images or data in various wavelengths of the electromagnetic spectrum, such as visible, infrared, or microwave. Remote sensing satellites are also called Earth
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
