Service Description: This image service was developed using data from over 213,000 national forest inventory plots measured during the period 2014-2018 from the USFS Forest Inventory and Analysis (FIA) program, in conjunction with other auxiliary information. Roughly 4,900 Landsat 8 OLI scenes, collected during the same time period, were processed to extract information about vegetation phenology. This information, along with climatic and topographic raster data, were used in an ecological ordination model of tree species. The model produced a feature space of ecological gradients that was then used to impute FIA plots to pixels. The plots imputed to each pixel were then used to assign values for stand age, stocking (percent), and Lorey's height. Raster function templates are imbedded within this service for visualizing each layer.
Band descriptions are as follows:
Band_1 All - Live - Tree Stocking Percent (COND.ALSTK) (Percent)
Band_2 Stand Age (COND.STDAGE) (Years)
Band_3 Lorey's Height (TREE.HT weighted by TREE.DIA) (Feet)
Stocking class Class boundaries
- Nonstocked 0 - <10 percent
- Poorly stocked 10 - <35 percent
- Moderately stocked 35 - <60 percent
- Fully stocked 60 - 100 percent
- Overstocked > 100 percent
