gNATSGO（网格化国家土壤调查地理数据库）
由于图像收集的范围和规模，该数据集将分批更新。 在采集和测试过程中，这些数据集将主要在内部人员专用数据集中提供。 一旦所有栅格集合都被采集，社区目录的所有用户都可以使用这些数据集。
数据集说明
gNATSGO（网格化国家土壤调查地理数据库）数据库是一个综合数据库，完整覆盖了美国所有地区和岛屿领土的最佳可用土壤信息。 本数据集仅提供栅格数据。 由于数据的原始格式为专有格式，因此源 COG 数据来源于 Planetary Computer STAC 目录。 gNATSGO 数据库由三个来源的数据组合而成：土壤调查地理数据库 (SSURGO)、州土壤地理数据库 (STATSGO2) 和栅格土壤调查数据库 (RSS)。 SSURGO 是 USDA-NRCS 土壤与植物科学部 (SPSD) 的旗舰土壤数据库，拥有 100 多年经实地验证的详细土壤制图数据。 SSURGO 包含美国 90% 以上地区和岛屿领土的土壤信息，但仍有未绘制地图的土地。 STATSGO2 是一个普通土壤地图，包含美国所有地区和岛屿领土的土壤数据，但数据不如 SSURGO 数据详细。 栅格土壤调查（RSS）是利用先进的数字土壤制图方法开发的下一代土壤调查数据库。 gNATSGO 数据库主要由 SSURGO 数据组成，STATSGO2 数据用于填补空白。 在合并 SSURGO 和 STATSGO2 数据后，RSS 被并入 gNATSGO。 目前，RSS 的范围相对有限，但预计在未来几年会有所增加。 要使用 mukey 栅格资产中包含的地图单位值，您需要连接到 gNATSGO 表集合中表示为 "项 "的表。 许多项目的常用值已在其他栅格资产中编码。
