EOS Terra ASTER : Volcanic topographic mapping and capability

  title={EOS Terra ASTER : Volcanic topographic mapping and capability},
  author={Nicki F. Stevens and Harold Garbeil and Peter J. Mouginis-Mark},
Up-to-date, accurate topographic data are a crucial resource for volcanic research and risk mitigation efforts, in particular, for modeling volcanic flow processes at a detailed spatial resolution. In this paper, we examine the utility of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument currently operating on the NASATerra satellite, which provides near infrared (VNIR) stereo imaging from which topography can be derived. We wrote software to generate digital… CONTINUE READING
