US Forest Atlas FIA Forest Type Groups All CONUS (Image Service)

This dataset portrays FIA National Forest Type Groups. Each group is a subset of the National Forest Type dataset which portrays 28 Forest Type Groups across the contiguous United States. Forest Type Groups are aggregations of forest types into logical ecological groupings. These data were derived from MODIS composite images from the 2002 and 2003 growing seasons in combination with nearly 100 other geospatial data layers, including elevation, slope, aspect, ecoregions, and PRISM climate data.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog. Data for this record includes the following resources: ISO-19139 metadata ArcGIS Hub Dataset ArcGIS GeoService For complete information, please visit https://data.gov.本数据集呈现FIA国家森林类型组（FIA National Forest Type Groups）。每个类型组均为国家森林类型数据集的子集，该数据集涵盖美国本土48州的28个森林类型组。森林类型组是将各类森林类型按合理生态逻辑归并整合的集合体。本数据集源自2002年与2003年生长季的MODIS（中分辨率成像光谱仪）合成影像，并结合了近百个其他地理空间数据图层，包括海拔、坡度、坡向、生态区以及PRISM气候数据。本数据集条目源自USDA（美国农业部）企业数据清单，该清单的数据汇入https://data.gov数据目录。本数据集条目包含以下资源：ISO 19139元数据、ArcGIS Hub数据集以及ArcGIS地理服务。如需获取完整信息，请访问https://data.gov。
