Gridded National Soil Survey Geographic Database (gNATSGO)

The gridded National Soil Survey Geographic Database (gNATSGO) is a USDA-NRCS (Natural Resources Conservation Service) Soil & Plant Science Division (SPSD) composite ESRI file geodatabase that provides complete coverage of the best available soils information for all areas of the United States and Island Territories. It was created by combining data from the Soil Survey Geographic Database (SSURGO), State Soil Geographic Database (STATSGO2), and Raster Soil Survey Databases (RSS) into a single seamless ESRI file geodatabase.
The gNATSGO database contains a 10-meter raster of the soil map units and 70 related tables of soil properties and interpretations. It is designed to work with the SPSD gSSURGO ArcTools. Users can create full coverage thematic maps and grids of soil properties and interpretations for large geographic areas, such as the extent of a State or the conterminous United States.
SSURGO is the SPSD flagship soils database that has over 100 years of field-validated detailed soil mapping data. SSURGO contains soils information for more than 90 percent of the United States and island territories, but unmapped land remains. The current completion status of SSURGO mapping is displayed (PDF). STATSGO2 is a general soil map that has soils data for all of the United States and island territories, but the data is not as detailed as the SSURGO data. The Raster Soil Surveys (RSSs) are the next generation soil survey databases developed using advanced digital soil mapping methods.
The first version of gNATSGO was created in 2019. It is composed primarily of SSURGO data, but STATSGO2 data was used to fill in the gaps. Three RSSs have been published as of 2019. These were merged into the gNATSGO after combining the SSURGO and STATSGO2 data. The extent of RSS is expected to increase in the coming years.

国家土壤调查网格地理数据库（gNATSGO）是由美国农业部自然资源保护服务局（Natural Resources Conservation Service）土壤与植物科学部（Soil & Plant Science Division）创建的复合ESRI文件地理数据库，旨在为美国及岛屿领土的所有区域提供最完善的土壤信息覆盖。该数据库通过整合土壤调查地理数据库（SSURGO）、州级土壤地理数据库（STATSGO2）和栅格土壤调查数据库（RSS）的数据，构建成为一个单一的连续ESRI文件地理数据库。gNATSGO数据库包含10米分辨率的土壤图斑栅格数据以及70个相关表格，记录了土壤属性及解读。该数据库旨在与SPSD gSSURGO ArcTools协同工作，用户可创建覆盖大范围地理区域的土壤属性及解读的专题地图和网格数据，例如州或美国大陆的范围。SSURGO是美国SPSD的旗舰土壤数据库，拥有超过100年的现场验证的详细土壤测绘数据，覆盖了美国及岛屿领土超过90%的区域，但仍存在未测绘的土地。当前SSURGO测绘的完成情况以PDF形式展示。STATSGO2是一般土壤图，包含了美国及岛屿领土的土壤数据，但其数据不如SSURGO详细。栅格土壤调查（RSSs）是利用先进的数字土壤测绘方法开发的下一代土壤调查数据库。2019年创建了gNATSGO的第一版，主要由SSURGO数据组成，但利用STATSGO2数据填补了空白。截至2019年已发布三个RSSs，这些数据在整合SSURGO和STATSGO2数据后并入gNATSGO。预计RSS的范围在未来几年将扩大。本数据集包含的资源：资源标题：国家土壤调查网格地理数据库（gNATSGO）网站指针。文件名：网页，URL：https://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/survey/geo/?cid=nrcseprd1464625。gNATSGO网站提供概述幻灯片演示、gNATSGO数据库（CONUS或州）的下载链接、ArcTools、元数据、技术信息和推荐数据引用。
