Impact/Purpose:
Our research objectives are to: (a) develop new methods using satellite remote sensor data for the rapid characterization of LC condition and change at regional to national scales; (b) evaluate the utility of the new NASA-EOS MODIS (Moderate Resolution Imaging Spectrometer) leaf area index (LAI) measurements for regional scale application with landscape process models (e.g., biogenic emissions and atmospheric deposition); (c) provide remote sensor derived measurement data to advance the development of the next generation of distributed landscape process-based models to provide a predictive modeling capability for important ecosystem processes (e.g., nutrients, sedimentation, pathogens, etc.); and (d) integrate in situ monitoring measurement networks with UAV and satellite based remote sensor data to provide a continuous environmental monitoring capability.
Description:
The Multi-Resolution Land Characteristics (MRLC) consortium, a cooperative effort of several U .S. federal agencies, including. the U.S. Geological Survey (USGS) EROS Data Center (EDC) and the U.S. Environmental Protection Agency (EP A), have jointly conducted the National Land Cover Data (NLCD) program. This program used Landsat Thematic Mapper (TM) 30 m resolution imagery as the baseline data and successfully produced a consistent and conterminous land-cover (LC) map of the lower 48 states at approximately an Anderson Level II thematic detail. The primary goal of the program was to provide a generalized and regionally consistent LC product for use in a broad range of applications (Lunetta et al., 1998). Each of the 10 U.S. federal geographic regions was mapped independently. EPA funded the Center for Earth Observation (CEO) at North Carolina State University (NCSU) to assess the accuracy of the NLCD for federal geographic Region IV .
