This is an image service contains pixel data for 327 individual tree species as well as total live tree aboveground forest biomass (tons/acre), 2014-2018. An efficient approach for mapping multiple individual tree species over large spatial domains was used to develop these raster datasets. The method integrates vegetation phenology derived from dense time series of Landsat imagery and raster data describing relevant environmental parameters with extensive field plot data of tree species aboveground biomass to create maps of tree species abundance and distribution at a 30-meter (m) pixel size for the Conterminous United States (CONUS). The approach uses the modeling techniques of k-nearest neighbors and canonical correspondence analysis, where model predictions are calculated using the mean of the nearest neighbors based on proximity in a feature space derived from the model.<\/span><\/p>

Each species layer has undergone an extensive validation process and resulting statistics and data layers will soon be available here on ArcGIS Online and via our upcoming BIGMAP data dashboard.<\/span><\/p><\/div><\/div><\/div>", "licenseInfo": "
