{ "currentVersion": 11.3, "cimVersion": "3.3.0", "id": 3, "name": "Total Forest Carbon (2018)", "type": "Raster Layer", "description": "The Total Forest Carbon 2018 map was developed by Forest Service scientists using data from FIA plots measured between 2014-2018, in conjunction with remote sensing data. More info is available here - https://usfs.maps.arcgis.com/home/item.html?id=bd3c2c1ba3844ebabd8df6d1c4932387 . 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 (tons per pixel) for total forest carbon.
