					Soil Data Join Recorrelation Initiative
  • Overview and Background
      – Purpose, Issues, Objectives, Initiative
  •   Advisory Team / Technical Team
  •   National Instruction Highlights
  •   Reportable Measures
  •   FY12 and Beyond
         Overview and Background

• Chief’s decision memo regarding NASIS
  – Improve the database
  – Accelerate MLRA approach by re-correlating data
    joins (harmonization)
  – Accelerate Phase 1 of MLRA update


  – Goal is seamless soil survey data
    Soil Data Join Recorrelation (SDJR)
            (a.k.a. Harmonization)
What is it?
• Effort to provide seamless soil survey information in a
  timely fashion
• Correlation and data enhancement using legacy soils
  data to provide seamless soils data
• One data mapunit or consistent properties correlated
  to geographically consistent map units
      • Same named
      • Similar named
      • Uniquely named
                           SDJR
                            Why now?
•   It has been a SSD Director priority for at least 2 years
•   With the completion of SSURGO many added value
    products are being generated
•   We need to provide consistent data for USDA programs
•   If we don’t do this, others (non-soil scientists) will make
    changes to make data consistent
•   We have enough data to make decisions for many
    instances
•   Many soil scientists that have key knowledge for making
    these decisions will likely be retiring soon
       National Soil Survey Database
           Harmonization Project
                     Why now?

• Allows for SSOs and MOs to do a thorough analysis
  of all their data
• Through this analysis long range and yearly plans,
  and projects can be developed and prioritized
• Using Benchmark Soils, we can harmonize/make
  consistent a large percentage of our data
Division Priority

• FY- 2012 Soils Division Priorities
  – Begin a multi-year initiative to complete Soil
    Survey Data Join Re-correlation (often referred to
    as harmonization) so that soils information
    matches from county to county and state to state
    on 1 billion acres
Division Director Charge:


• Establish Advisory and Technical teams to look at
  accelerating Phase I (data harmonization) of MLRA
  updates
   – Provide advice for implementation
   – Develop objectives, goals, and direction

What are the issues?
                What are the issues?

• K factors are one
  interpretation dependent
  on texture that are
  dependent on map unit
  concept
               What are the issues?

• Same map unit
  name, different
  composition
                  What are the issues?

Expectation of consistent
interpretations:

                                          After
Basic Objectives - SDJR


• Support the development of seamless soils data for
  use with CDSI, USDA Farm Bill Programs, and
  added value SSURGO products

• Process resulting in correlation of similar data map
  units taking into account existing legacy data,
  laboratory data, and expert knowledge
  Basic Objectives - SDJR
• Dissolve the perceived data faults in interpretations
  visible in geospatial presentation of soil survey
  information


 Often resulting from
 minor variation in data
 population, horizon
 depths, composition,
 and vintage of
 guidance documents
Basic Objectives - SDJR
• Improve the database

• Reduces the number of DMU’s for same and similarly
  named soil map units

• Identify priority update needs

• Builds the foundation for next generation of soil
  survey – disaggregation
