ASTER Sensor Characteristics of ASTER Sensor Operation of ASTER Sensor ASTER GDS ASTER Products Path & Calendar Coverage Map EOS Project	ASTER(Advanced Spaceborne Thermal Emission and Reflection Radiometer) Sensor, a high spatial resolution imaging sensor, consists of visible and near infrared (VNIR), short-wave infrared (SWIR) and thermal infrared (TIR) regions subsystems and capable of simultaneously operating in wide spectral ranges. Characteristics of ASTER Sensor Operation of ASTER Sensor The detailed information about ASTER sensor is in ASTER User's Guide(Part-I). ASTER Spectral Profiles is offered in a MS-EXCEL file. The spectral profiles of VNIR、SWIR and TIR are provided by each book of the file. ASTER Spectral Profiles 240KB Please refer to the ASTER User's Guide Part-I for detailed information of ASTER sensor.
