1. Setup

  • Bulk SSURGO Download by Areasymbol - Use Soil Data Access and Web Soil Survey download page to get SSURGO datasets. User can a wildcard to query the database by Areasymbol.
  • Generate Local Transactional Geodatabase - Used to create the Local Transactional Spatial Database (LTSD) for to check out datasets to local MLRA offices to edit and udate.
  • Generate Regional Transactional Geodatabase - Used to create the Regional Transactional Spatial Database (RTSD) for SSURGO.
  • Generate SSO SSURGO Datasets - obsolete.
  • Import SSURGO Datasets in FGDB - This tooll will import SSURGO spatial and tabular datasets within a given location into a File Geodatabase and establish the necessary table and feature class relationships to interact with the dataset.
  • Insert NATSYM and MUNAME Value - This tool adds the National Mapunit Symbol (NATMUSYM) and the Mapunit Name (MUNAME) values to the corresponding MUKEY. An MUKEY field is required to execute. A network connection is required in order to submit a query to SDacess.
  • RTSD - Check SDJR Project Out - Designed to work with the RTSD to manage SDJR projects and export data for those projects to be sent to the MLRA SSO.

2. Quality Assurance

  • Check Attributes - Checks formatting of the selected soil attributes (normally AREASYMBOL and MUSYM). Also checks to make sure that the AREASYMBOL is present in Web Soil Survey.
  • Compare Spatial-NASIS Mapunits - Check MUSYM values in the input layer using a NASIS online report. Internet connection required for this tool.
  • Find Common Lines - Compares attributes between adjacent polygons and flags those that are the same.
  • Find Common Points - Find points where polygon with the same attribute value intersect. These are usually soil polygons that get 'pinched off'. This will also flag self-intersecting polygons.
  • Find Edge Match Errors - Looks for locations along survey boundaries where a node-to-node match does not exist. It does NOT look at soil attribute matches.
  • Find Multipart Features - Simply reports the existence of multipart polygons. These must be exploded in an edit session if they are detected.
  • Find Slivers - Looks for slivers or gaps in a polygon layer based upon a minimum-allowed internal polygon angle. Often smaller angles are the result of snapping vertices that create slivers, zig zags or bowties.
  • Find Vertex Problems - Calculate area statistics by state or survey area from a GCS polygon featureclass and find problem vertices
  • Report Vertex Count - Simply reports the number of vertices found in the input featureclass. This tool is useful when the user wants to find out how many vertices were present 'before-and-after'.
  • Report Vertex Densisty - Calculate area statistics by state or survey area from a polygon featureclass. Can be used to determine what surveys are potential candidates for thinning or may have vertices that are liable to contribute to snapping or other geometry problems.

3. Certification

  • Bulk MUSYM update tool - Update all soil polygon map unit symbols from cross walk table.
  • Shoehorn - Import MUPOLYGON changes to the RTSD MUPOLYGON, reduces vertices, amends acute angles and ensures fit within SAPOLYGON.
  • Export to SSURGO Shapefile - Export geodatabase featureclasses to SSURGO shapefile format. These shapefiles are suitable for posting to the Staging Server.
  • Convert .txt to .met - Will convert a folder of updated text metadata files xml .met format and save them to respective SSURGO export folder.
  • Generate Special Feature File - Creates the feature description text file-table for SSURGO.
  • Zip SSURGO Export Folders - Zips all of the required SSURGO shapefiles and feature file for posting to the Staging Server.
