Team Charges

  • Review existing and historic DMU population standards.
  • Develop an updated set of DMU population standards.

    Minimum Standard – For existing DMUs.
       – Intended for older vintage data sets transferred in from SSSD or populated in the earlier versions of
       – Allows for rapid improvement of SSURGO without causing too much work.

    Full Standard – For all new DMUs and those DMUs that undergo significant edits in update projects.
  • Create NASIS reports to ensure NASIS DMU data comply with the standards.


New NASIS report folder called ‘Data Integrity’. Reports include:

  • READ FIRST ABOUT DATA INTEGRITY REPORTS. This explains how reports in the Data Integrity Site are used to bring NASIS data to a common national minimum standard.
  • Minimum Standard (Legend, Mapunit, Data Mapunit). This report lists the Minimum Data Population Standard. 
  • Data integrity check reports are under development. These will evaluate existing NASIS DMU data for those data elements in the Minimum Standard.
