What is RS Remote Sensing is the science or the technique of deriving information about objects at the Earth surface from images using (parts of) the electromagnetic spectrum Measuring electromagnetic energy (light), reflected or emitted Non-destructive method, no physical contact Surveying the spatial distribution of objects Determining properties of objects Monitoring the dynamics of features

ASTER/MODIS Product Description The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of a number of instruments on board the Terra platform,Terra which was launched in December ASTER provides fourteen spectral bands with 15- to 90-meter resolution depending on bands. ASTER does not acquire data continuously, and its sensors are activated only to collect specific scenes upon request. The instrument consists of three separate telescopes, each of which provides different spectral range and resolution. The VNIR (visible and near-infrared) sensor provides 4 bands at 15-meter resolution. The SWIR (short-wave infrared) sensor provides 6 bands at 30-meter resolution. The TIR (thermal infrared) sensor provides 5 bands at 90-meter resolution. The swath width for all sensors is 60 kilometers. ASTER data is generally available in the Universal Transverse Mercator (UTM) projection, although some individual scenes may be cast to an alternative projection. The data is referenced to the World Geodetic Survey (WGS) system of 1984 (WGS84). Files are in the HDF-EOS format, and are distributed on CD-ROM, DVD, DLT, 8-mm tape, and File Transfer Protocol (FTP).
