Forest Inventory and Analysis Above Ground Forest Carbon (Image Service)

Through application of a nearest-neighbor imputation approach, mapped estimates of forest carbon density were developed for the contiguous United States using the annual forest inventory conducted by the USDA Forest Service Forest Inventory and Analysis (FIA) program, MODIS satellite imagery, and ancillary geospatial datasets. This data product contains the following 8 raster maps: total forest carbon in all stocks, live tree aboveground forest carbon, live tree belowground forest carbon, forest down dead carbon, forest litter carbon, forest standing dead carbon, forest soil organic carbon, and forest understory carbon. The paper on which these maps are based may be found here: https://dx.doi.org/10.2737/RDS-2013-0004本研究采用最近邻插补法（nearest-neighbor imputation），依托美国农业部（USDA）林务局森林资源清查与分析（Forest Inventory and Analysis, FIA）项目的年度森林清查数据、MODIS（Moderate Resolution Imaging Spectroradiometer）卫星影像以及辅助地理空间数据集，生成了美国本土地区的森林碳密度制图估算结果。 该数据产品包含以下8幅栅格地图：全碳库森林总碳储量、活立木地上森林碳储量、活立木地下森林碳储量、森林枯倒木碳储量、森林枯落物碳储量、森林枯立木碳储量、森林土壤有机碳储量以及森林林下植被碳储量。 本套制图所依托的相关研究论文可通过以下链接获取：https://dx.doi.org/10.2737/RDS-2013-0004
