Soil Data Access is the name of a suite of web services and applications whose purpose is to meetrequirements for requesting and delivering soil survey spatial and tabular data that are not met bythe Web Soil Survey and Geospatial Data Gateway websites. These requirements include:
Soil Data Viewer is a tool built as an extension to ArcMap that allows a user to create soil-based thematic maps. The application can also be run independent of ArcMap, but output is then limited to a tabular report.
The soil survey attribute database associated with the spatial soil map is a complicated database with more than 50 tables. Soil Data Viewer provides users access to soil interpretations and soil properties while shielding them from the complexity of the soil database. Each soil map unit, typically a set of polygons, may contain multiple soil components that have different use and management. Soil Data Viewer makes it easy to compute a single value for a map unit and display results, relieving the user from the burden of querying the database, processing the data and linking to the spatial map.
Soil Data Viewer contains processing rules to enforce appropriate use of the data. This provides the user with a tool for quick geospatial analysis of soil data for use in resource assessment and management.
The Soil Survey Geographic Database (SSURGO) contains information about soil as collected by the National Cooperative Soil Survey over the course of a century. The information was gathered by walking over the land and observing the soil. Many soil samples were analyzed in laboratories.
The SSURGO database contains information about soil as collected by the National Cooperative Soil Survey over the course of a century. The information can be displayed in tables or as maps and is available for most areas in the United States and the Territories, Commonwealths, and Island Nations served by the USDA-NRCS. The information was gathered by walking over the land and observing the soil. Many soil samples were analyzed in laboratories. The maps outline areas called map units. The map units describe soils and other components that have unique properties, interpretations, and productivity. The information was collected at scales ranging from 1:12,000 to 1:63,360. More details were gathered at a scale of 1:12,000 than at a scale of 1:63,360. The mapping is intended for natural resource planning and management by landowners, townships, and counties. Some knowledge of soils data and map scale is necessary to avoid misunderstandings.
The maps are linked in the database to information about the component soils and their properties for each map unit. Each map unit may contain one to three major components and some minor components. The map units are typically named for the major components. Examples of information available from the database include available water capacity, soil reaction, electrical conductivity, and frequency of flooding; yields for cropland, woodland, rangeland, and pastureland; and limitations affecting recreational development, building site development, and other engineering uses.
SSURGO datasets consist of map data, tabular data, and information about how the maps and tables were created. The extent of a SSURGO dataset is a soil survey area, which may consist of a single county, multiple counties, or parts of multiple counties. SSURGO map data can be viewed in the Web Soil Survey or downloaded in ESRI Shapefile format. The coordinate systems are Geographic. Attribute data can be downloaded in text format that can be imported into a Microsoft Access database.

I'm working on my project for one of my design classes and need to generate a soil map data using SSURGO data to work of for my project. I'm aware in the regular ArcMap, you need to install the soil data viewer add-in. My question is can this extention work in Pro or, if not, then any solution on how I can go about creating the soil map?
Soil scientists, hydrogeologists, municipal water-utility operators and water-quality regulators use soils lab data to understand the subsurface. The data viewer includes more than 50,000 individual soil samples from across the world. Soil sample data can also be viewed in reports.
Soil Data Viewer still only recognizes a Microsoft Access database with a .mdb extension. We do not yet provide SSURGO Template databases in .accdb format. Microsoft Access 2007 and 2010 are both capable of working with an Access database in .mdb format. Our intent is remedy this as soon as possible.
Gridded SSURGO (gSSURGO) is similar to the standard USDA-NRCS Soil Survey Geographic (SSURGO) Database product but in the format of an Environmental Systems Research Institute, Inc. (ESRI) file geodatabase.

The gSSURGO CONUS database is too large for download as a single zip file. It has been split into smaller files for ease of download. All files must be downloaded to access gSSURGO CONUS. A pdf of instructions is available for download with the gSSURGO for CONUS link above.
Gridded SSURGO (gSSURGO) is similar to the standard USDA-NRCS Soil Survey Geographic (SSURGO) Database product but in the format of an Environmental Systems Research Institute, Inc. (ESRI) file geodatabase. A file geodatabase has the capacity to store much more data and thus greater spatial extents than the traditional SSURGO product. This makes it possible to offer these data in statewide or even conterminous United States (CONUS) tiles. gSSURGO contains all of the original soil attribute tables in SSURGO. All spatial data are stored within the geodatabase instead of externally as separate shapefiles. Both SSURGO and gSSURGO are considered products of the National Cooperative Soil Survey (NCSS) partnership.
The gridded SSURGO (gSSURGO) dataset was created for use in national, regional, and statewide resource planning and analysis of soils data. The raster map layer data can be readily combined with other national, regional, and local raster layers, including the National Land Cover Database (NLCD), the National Agricultural Statistics Service (NASS) Crop Data Layer (CDL), and the National Elevation Dataset (NED).
The Create Soil Map tool replicates the functionality of Web Soil Survey and Soil Data Viewer. It allows users to create on demand thematic maps of soil properties or interpretations with controls for aggregation method and depth.
The gridded National Soil Survey Geographic Database (gNATSGO) is a USDA-NRCS Soil & Plant Science Division (SPSD) composite database that provides complete coverage of the best available soils information for all areas of the United States and Island Territories.
The gridded National Soil Survey Geographic Database (gNATSGO) is a USDA-NRCS-SPSD composite database 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 databases are available for some individual states and island territories and for the conterminous United States (CONUS). Not all states have a gNATSGO database. For the individual states and island territories, gNATSGO was created only for those that have incomplete data in SSURGO or have an RSS.
The gNATSGO databases contain a rasterized version of the soil map units and 70 related tables of soil properties and interpretations. They are designed to work with the custom USDA-NRCS Soil Data Development ArcToolbox (See below for more information about the tools). 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 CONUS. Note, the custom tools currently only work in ArcGIS Desktop ArcMap. They do not currently work in ArcGIS Pro.
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. Click here for the current completion status of SSURGO mapping. 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 gNATSGO database is composed primarily of SSURGO data, but STATSGO2 data was used to fill in the gaps. The RSSs are newer product with relatively limited spatial extent. These RSSs were merged into the gNATSGO after combining the SSURGO and STATSGO2 data. The extent of RSS is expected to increase in the coming years.
Figure 1 shows the distribution of SSURGO, STATSGO2, and RSSs in gNATSGO for CONUS. Limited SSURGO data is available for Alaska because of the size and difficulty in accessing many areas of the State. Figure 2 shows the distribution for Alaska. The State of Hawaii and all island territories, except Puerto Rico, have complete coverage in SSURGO.

The create soil map tool is part of the Soil Data Development Toolbox (See above for more information about the tools). This tool replicates the functionality of Web Soil Survey and Soil Data Viewer. It allows users to create on-demand thematic maps of soil properties or interpretations with controls for aggregation method and depth. It analyzes the tables of soils information in the gNATSGO database and joins the results to the raster layer, outputting a temporary layer file. The following instructions show how to convert temporary custom thematic map layers to stand alone grids that can be used in spatial analyses.
