Forest Service Research and Development (R&D) and State and Private Forestry Deputy Areas, in partnership with the National Forest System Remote Sensing Applications Center (RSAC), built a 250-m resolution (6.25-ha pixel) dataset for the entire USA. It assembles multi-seasonal hyperspectral MODIS data and derivatives, Landsat derivatives (i.e., summary statistics for the 70 or so Landsat pixels within each 6.25-ha pixel), and other national geospatial datasets (e.g., climate, soils, ecoregions). All datasets are re-sampled to the same 250-m grid used for standard MODIS derivatives. There are approximately 100 layers in this “stack” of full-coverage geospatial data.
