FIA Above Ground Forest Biomass (Image Service)

The U.S. has been providing national-scale estimates of forest carbon stocks and stock change to meet United Nations Framework Convention on Climate Change reporting requirements for years. Through application of a nearest-neighbor imputation approach, mapped estimates of forest biomass 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 would contain the following 7 raster maps: Aboveground Forest Biomass, Belowground Forest Biomass, Forest Tree Bole Biomass, Forest Sapling Biomass, Forest Stump Biomass, Forest Top Biomass, Woodland Specias Biomass. All layers have a 250 meter pixel resolution and values represent biomass pounds per acre.  The paper on which these maps are based may be found here: https://dx.doi.org/10.2737/RDS-2013-0004  Access to full metadata and other information can be accessed here: https://dx.doi.org/10.2737/RDS-2013-0004This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

美国已连续多年提供国家尺度的森林碳储量及其变化估算，以满足联合国气候变化框架公约的报告要求。通过应用最近邻插补方法，利用美国农业部森林服务局森林资源清查与分析（FIA）项目开展的年度森林清查、MODIS卫星影像以及辅助地理空间数据集，开发了覆盖美国本土的森林生物量密度映射估算。该数据产品包含以下7幅栅格地图：地上森林生物量、地下森林生物量、森林树干生物量、森林幼苗生物量、森林树桩生物量、森林树冠生物量和林地物种生物量。所有图层均具有250米像素分辨率，数值表示每英亩的生物量磅数。基于这些地图的论文可在此处查阅：https://dx.doi.org/10.2737/RDS-2013-0004。完整元数据和相关信息可通过以下链接获取：https://dx.doi.org/10.2737/RDS-2013-0004。本记录源自美国农业部企业数据清单，该清单汇入https://data.gov目录。本记录的数据资源包括以下内容：ISO-19139元数据、ArcGIS Hub数据集、ArcGIS GeoService。欲获取完整信息，请访问https://data.gov。
