ASTER, or the Advanced Spaceborne Thermal Emission and Reflectance Radiometer, is a state-of-the-art imaging instrument onboard NASA's Terra satellite. Terra was launched in 1999 and has five instrument sensor systems, with ASTER being one of them. It provides a unique combination of wide spectral coverage and medium spatial resolution, making it valuable for a wide array of applications, including hazard monitoring, geology and soils, and land surface climatology. ASTER consists of three subsystems - VNIR, SWIR, and TIR - and is capable of generating along-track stereo image pairs for creating digital elevation models.
Multispectral and thermal imaging for vegetation, soil, hydrology, and resource management applications.
Swath width of 60km at nadir, providing broad coverage for a range of applications
Used within Geoimage's Spectral Suite, a set of image enhancements that make use of data from ASTER.
