Mapping Canopy Structure & Biomass with Multiangle EOS Data

Mapping Canopy Structure & Biomass in the SW US with Multiangle EOS Data

Objectives	To provide new ways of mapping woody plants (fractional canopy cover, canopy height, and aboveground woody biomass) and plant communities over large areas and at low cost by exploiting the directional signal in NASA Earth Observing System data from MISR and MODIS. Our results are documented in these pages and in our publications [background]. We are also applying these techniques to map changes in shrub cover in Arctic tundra.	012345678901234567890
