ASTER is a 15 meter, 14 band multispectral resolution instrument. It can be used for change detection, calibration, validation, and land surface studies.

ASTER satellite image data is expected to contribute to a wide array of global change-related application areas, including vegetation and ecosystem dynamics, hazard monitoring, geology and soils, land surface climatology, hydrology, land cover change, and the generation of digital elevation models (DEMs).

ASTER high-resolution satellite capable of producing stereo imagery for creating detailed digital terrain models (DTMs).

ASTER Satellite Sensor Specifications

The ASTER instrument consists of three separate instrument subsystems:

VNIR (Visible Near Infrared), a backward looking telescope which is only used to acquire a stereo pair image

SWIR (ShortWave Infrared), a single fixed aspheric refracting telescope

TIR(Thermal Infrared)

ASTER has 14 bands of information. For more information, please see the following table:
