Northern Eurasia Land Dynamics Analysis

The Northern Eurasia Land Dynamics Analysis (NELDA) harnessed NASA remote sensing technology and local knowledge of land-cover conditions in order to validate and improve land cover/land-cover change products for Northern Eurasia.  The NELDA project established a network of test sites for analyzing land cover, land-cover change, and disturbance captured with time series of Landsat-resolution imagery.  The test sites provided data for validation of existing coarse-resolution land-cover products and samples of important vegetation change and disturbance processes. We used these samples to develop and test methods for continental mapping of vegetation disturbance.  Finally, we produced a new, updated land cover map for Northern Eurasia based on MODIS data for circa 2005 at 500-m spatial resolution.
