Objectives • Contrast the general and detailed evaluations • Understand what is to assessed in the detailed evaluation process • Compare manuscripts and databases • Identify tools for assessing quality and consistency of data
How many surveys are in your territory? • Use Chat Pod to provide your number.
Detailed Evaluation Process Prior to any soil survey updating activity, an evaluation of the map units overall condition of the original survey areas is required. Evaluations are the first step in all project plans Results of the Evaluation are used to complete the Project Plan
In your opinion, what needs to be assessed in the detailed evaluation process for the project plan? • Use a chat poll.
Data to be Assembled 610.03c • map unit descriptions • unpublished soil information • field review reports • correlation records • records documenting soil survey joining problems • interpretations • special investigation and laboratory data • pedon descriptions • transect data • tacit knowledge of those experienced in the area • notes of needed changes recorded in the office copy of the published soil
Items to consider 610.03c • map unit design/composition • soil delineations conform to landform positions • adequacy of the database to support interpretations • need for laboratory or other support data • appropriate level of detail • adequacy of the imagery • land use change • classification
What do you consider to be the first step in evaluating your Project? Use Chat Pod to write your answer
NASIS Review Reviewing the map units and components within the Project
Loading MLRA Data into NASIS Overlap tables are to be populated with the MLRA and map units assigned to that MLRA This should be the first step in developing the Project
What component has the highest number of acres in your MLRA? • Use Chat Pod to provide your number.
What map unit has the highest number of acres in your MLRA? • Use Chat Pod to provide your number.
Step 1: • Run thePangaeareports • No selected set is needed • Reports prompt for MLRA
Step 2: Components in Excel Export Reports can be sorted using Excel
Step 3 • Save the results to your PC and import into Excel
Step 4 • Now sort based on the acres to find Fayette has the greatest number of acres
Compare components to benchmark • Should the high acre components be benchmark soils?
Step 5: Mapunit acres? • Well, what about map units? We have reports for that – first formatted
Step 6: Formatted • Formatted and sorted by name
Step 7: Mapunits in Excel • Do you want to sort by acres?
Step 8 • Fayette, 9 to 14 has the highest number of acres
Priorities • The goal of update is to update the mapunits to a common standard • Identify the cost:benefit ratio • Fayette silt loam 9 to 14 or • Steep stony and rocky land? • These reports are used during the prioritizing of work load
Analyze NASIS Property Data Reporting Physical Properties for a component
Analyze NASIS Property Data NASIS reports are available to assist in the location of property voids or identify data population inconsistencies.
Manuscript Review Reviewing map unit descriptions in comparison to NASIS population
Process Steps Now you have identified map unit and components to be evaluated, next step: • Compare the Map Unit Descriptions to identify the map unit design for each map unit • Compare the Taxonomic Unit Descriptions to identify the component concept for each component • Review correlation documents • Compare the property and interpretation tables in the manuscript to identify potential over-rides
Is it the same mapunit? 1999 1939
MUD and TUD • Just as a reminder this same review process should be completed on the TUD/OSD/Pedon. • What are the considerations of old pedons?
Manuscript versus NASIS Review • Map unit concept is maintained in the manuscript. Manuscripts MUST be reviewed. • NASIS contains soil properties and was designed based on a map unit concept. • Original NASIS data was converted from the State Soil Survey Database (SSSD). SSSD data based on a series concept (SOI5)
What is a SOI-5? • The data entry form used to populate the State Soil Survey Database (SSSD)
