Mapping South Asian dry dipterocarp forest using dualseason satellite imagery

Download to read offline

Dry dipterocarp forest is an endangered South Asian habitat type. Conservation is difficult because few good maps exist: dry dipterocarp is particularly hard to detect using conventional remote sensing. Working with an extensive set of ASTER and MODIS satellite images, we developed a multi-season multi-satellite methodology for mapping this illusive landcover.

This presentation was given at the Smithsonian Institution annual GIS day in 2005.
