GNN Forest Structure (Species-Size) Maps Western US

This data set is obtained from the Forestry Group at Oregon State and it is an input to the analysis presented in this data set. <br>Digital GNN imputation maps are provided as 30-m-resolution ArcGIS grids, where the grid value is a unique plot number that links to the plot database. Selected vegetation variables from the plot database are joined as items in the grid to facilitate viewing and exploratory spatial analysis. Metadata for the vegetation variables are included with the grids and in the plot database. Dates for maps developed from GNN species-size models are determined by the vintage of the satellite imagery used in their development.<br>
