									    Soil Data Join Recorrelation
• 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
                          Why now?
•   It has been a SSD Director priority for at least 2
•   With the completion of SSURGO many added value
    products are being generated
•   We need to provide consistent data for USDA
•   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
     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
• 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
  dependent on texture
  that are dependent on
  map unit concept
             What are the issues?

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

Lines join,
s differ
Issues: Statewide Interpretations
Issues: Nationwide Soil Property Data


       Bulk Density, 5-20 cm (Mg m-3)
                  What are the issues?

Expectation of consistent

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
