1 Soil Data Join Recorrelation MO1 Approach to the Harmonization Process

2 Agenda 1.Introduction ›Brief review of NASIS structure ›Overview of the Soil Data Join Recorrelation (SDJR) initiative ›Acres goals and timelines ›Roles and responsibilities 2.Overview of national instruction 3.Map unit NASIS group assignment 4.Review SDJR data package 5.MO1 SDJR demonstration

3 NASIS review  These four objects (table and nested child tables) will be referenced: 1.Data Mapunit 2.Legend 3.Mapunit 4.Project

4 NASIS review  Data Mapunit ›Stores component data ›Links to the Mapunit object through the Correlation child table  Mapunit ›Linked to the Legend and Project objects ›Uniquely identified by the national mapunit symbol ›Links to the Legend object through the Legend Mapunit child table using the national map unit symbol

5 NASIS review  Mapunit ›Also is linked to the Project object through the Project Mapunit child table using the national map unit symbol Same method as linking a mapunit to a legend

6 NASIS review  Legend ›Will not be edited by the MLRA SSO ›Contains the Legend Mapunit child table Only thing that can be edited in this table is the map unit acres and map unit symbol (aka, publication symbol) Can edit. Can’t edit. Comes from Mapunit table.

7 NASIS review  Project ›How update soil survey is managed ›Created in NASIS 6 ›Used to manage map units, mapping goals, and progress ›MLRA SSO will be able to create and edit projects

8 Overview of SDJR  A national initiative designed to emphasize and accelerate the ongoing MLRA approach to soil survey  Requires an evaluation of all map units owned by a MLRA SSO  Will result in: ›Recorrelated and up-to-date map units, which will minimize the tabular data discrepancies that occur between similar or identical map units. ›A comprehensive list of future projects

9 Three SDJR Objectives 1.Evaluate map units in your MLRA SSA 2.Update NASIS for map units that can be harmonized 3.Document future projects identified during evaluation and harmonization

10 Overview of SDJR  NASIS database initiative ›Only working on tabular data (NASIS) ›Soil lines will not be edited  Intention is to improve joins between soil survey areas by reducing the number of unique map units and data map units (DMU) in NASIS

11 Overview of SDJR  Focuses on identically and similarly named map units, which are linked to more than one DMU  Intended result is for identically and similarly named map units to use the same up-to-date DMU  Legend map unit symbols will not be changed

12 Overview of SDJR Structure of Data Currently In NASIS Survey Area Symbol Map Unit NameMap Unit Symbol DMU Description WA631Agnew silt loam, 0 to 8 percent slopesAgB631AgB WA609Agnew silt loam, 0 to 8 percent slopes1609001 Expected New Structure of Data In NASIS Survey Area Symbol Map Unit NameMap Unit Symbol DMU Description WA631Agnew silt loam, 0 to 8 percent slopesAgBMLRA 1-1 2gp8 WA609Agnew silt loam, 0 to 8 percent slopes1MLRA 1-1 2gp8 A new up-to-date DMU is created and both map units are linked to it. The original legend map unit symbols are retained.

13 Overview of SDJR  NOT a spatial initiative  Soil lines will not be edited  At this time, the guidance for spatial editing is as follows: ›“Any time a spatial edit is required to complete a SDJR project, it is no longer a SDJR project, but instead becomes a future project.”

14 Overview of SDJR  NOT a spatial initiative  Soil lines will not be edited  Only potential spatial editing would be if a group of polygons of a map unit need to be correlated into two different map units ›Only the attribute table would be changed ›We expect this to happen rarely, if at all

15 Example Of Potential Spatial Edit  Map unit 037 – Meadowridge ashy sandy loam, 12 to 35 percent north slopes ›Occurs in both the 12-14 and 14-16 zone. ›Meadowridge is correlated to the “JD Sandy 10-14 PZ” ecological site ›In the 14-16 zone, Meadowridge needs to be correlated to the “SR Mountain 14- 16 PZ” ecological site

16 Example Of Potential Spatial Edit  A second map unit is set up ›038 - Medowridge ashy sandy loam, moist, 12 to 35 percent slopes Meadowridge in this map unit is correlated to SR Mountain 14-16 PZ ›The map unit symbols for the polygons in the 14-16 precipitation zone are changed from 037 to 038

17 Example Of Potential Spatial Edit  Soil lines were not changed  Only the map unit symbol was changed  Will require a re-certification of the soil lines

18 Overview of SDJR  New mapunits and DMUs created  Original map units retained and made additional in the Legend Mapunit table  Original DMUs retained and are linked as non- representative to the new map unit  No existing data will be modified  Only new data created

19 What Triggered SDJR?  The USDA-NRCS Soil Survey program intends to: ›Accelerate MLRA approach to soil survey ›Develop a “road map” for conducting update soil survey ›Create standards for updating tabular data ›Develop systematic and consistent methods for populating the Project Object

20 What Triggered SDJR?  The Soil Survey program needs to position itself as a viable program  Sell ourselves to the decision makers ›Thematic maps of proposed future projects can be generated ›The amount (acres of map units) of proposed work can be easily displayed

21 SDJR Technical Team  Charged with developing SDJR national instructions  Hold monthly teleconferences to discuss the SDJR initiative  Comprised of 20 people ›One SDQS from each MO ›Paul Finnell, NSSC NASIS Database Manager ›Cameron Loerch, National Leader, Soil Survey Standards

22 Who is Working SDJR?  All MLRA SSOs that are not working on initial or extensive revision soil surveys will be focusing on SDJR ›Those MLRA SSOs working on initial or extensive revision soil surveys will only harmonize matching map units and identify future projects

23 How Much Time Is Spent on SDJR?  At a minimum, it will be enough time to satisfy your SDJR acre goals  Expect to focus 50%-75% of your time on SDJR  Your remaining time will be spent working on already initiated update projects, evaluations, 01, etc….

24 What about field work?  SDJR is a database initiative  Projects that require field work are considered future MLRA projects  The short answer is there is no field work for SDJR

25 SDJR Timeline  FY12 ›MO staff assigns ownership of map units ›MO staff provides SDJR training ›MLRA SSOs evaluate map units Organize map units into proposed projects Begin identifying future projects ›MLRA SSOs complete at least one SDJR project Provide feedback to MO  FY13 ›SDJR officially begins ›Acre goals are set

26 Acre Goals  Who, when, and how acre goals are set is still to be determined  Goals will most likely be based on the map units that you own in NASIS  Same named or similar named map units included in goals????

27 Project Acre Goals  Each project will have an acre goal  Will be 20% of the total acres of map units included in your project  Populated in the Project Mapping Goal table

28 Progress Reporting  Progress will be reported for each SDJR project after QA and correlation are completed by the MO office  Progress is recorded in the Project Mapping Progress table as 20% of the map unit acres that were harmonized

29 Progress Reporting  The acres listed in the “Project Mapping Goal” table will not always equal the acres claimed in the “Project Mapping Progress” table ›All map units included in a proposed SDJR project will not always be harmonized ›In many instances, only some of the map units will be harmonizable ›Non-harmonizable map units will become future MLRA projects

32 Roles and Responsibilities  National Headquarters ›Provide direction ›Set goals ›Track progress and post results ›Brief states on initiative

33 Roles and Responsibilities  National Soil Survey Center ›Establish and guide SDJR Technical Team ›Provide national training ›Ensure consistency ›Provide national oversight on progress ›Develop success metrics to monitor progress

34 Roles and Responsibilities  State Soil Scientist ›Inform State Conservationists, cooperators, and users about priorities and progress ›Help establish priorities ›Certify data ›Serve as member of Management Team

35 Roles and Responsibilities  MLRA Regional Office (MO1) ›Train and support MLRA SSOs in the SDJR initiative Provide SDJR data sets ›Conduct QA on all SDJR projects ›Ensure consistency across MLRA SSOs ›Make changes to official legends in NASIS

36 Roles and Responsibilities  MLRA Soil Survey Offices ›Evaluate map units within the MRLA SSA ›Propose SDJR projects and future MLRA projects Follow SDJR national instructions for managing projects Document evaluation findings ›Complete approved SDJR projects Generate up-to-date MLRA map units ›Conduct QC on all completed SDJR projects

37 Roles and Responsibilities  MLRA Management Team ›Review, approve, and prioritize proposed SDJR projects

38 Projects  Each map unit owned by your MLRA SSO will be evaluated in placed in one of these categories: 1.SDJR Projects 2.MLRA Projects 3.Non-projects

39 Projects  SDJR Projects ›Proposed projects ›Require no field work or spatial edits ›Similarly or identically named map units ›Will contain SDJR at the beginning of the project name SDJR – MLRA 2 – Alpha silt loam 0 to 8 % slopes

40 Projects  MLRA projects ›Future projects ›Any project that requires field work or spatial line edits is a MLRA project ›Will contain MLRA at the beginning of the project name MLRA – MLRA 2 – Beta loams

41 Projects  Non – Projects ›Unique map units will not be included in SDJR or MLRA projects, unless you know these map units require some type of future project work

42 Projects  As you evaluate and attempt to update map units in a SDJR project, you may identify the need for additional field work before any updating of some or all of the map units can occur  In these instances, those map units identified as needing field work are shifted to a future MLRA project and your evaluation findings (what work needs to be done) is included in the project descriptions

43 Project Descriptions  Narrative statements that details history, location, acreage, reasoning for project, expected workload, theories, etc…  All projects must have a description  There are examples of project descriptions in the SDJR National Instructions, Exhibit D

44 Project Descriptions  Proposed SDJR projects ›Each SDJR project is a NASIS database update project ›Descriptions are expected to be relatively shorter and concise since the workload will be somewhat straight forward and similar for each project  Future MLRA projects ›Each MLRA project will be unique ›Descriptions are expected to be relatively longer and thorough since you will need to carefully outline the unique issues and expected workload

45 National Instructions  A harmonization road map  Supplemented with the following guides: ›National Soil Survey Handbook 608, 609, 610, & 627 ›Soil Survey Manual Chapter 2 ›NASIS 6.0 Training Materials Chapter 14 – Managing Update Projects ›MO1 Technical Note 38 & 40
