1
Detailed Project Plan Evaluation
2
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
3
How many surveys are in your territory? Use Chat Pod to provide your number.
4
Identifying Traditional Surveys
5
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
6
In your opinion, what needs to be assessed in the detailed evaluation process for the project plan? Use a chat poll.
7
Data to be Assembled 610.03c map unit descriptions unpublished soil information field review reports correlation records records documenting soil survey joining problems interpretations special investigation and laboratory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
8
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
9
What do you consider to be the first step in evaluating your Project? Use Chat Pod to write your answer
10
Where do you begin?
11
Correlation dates
12
NASIS Review Reviewing the map units and components within the Project
13
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
14
What component has the highest number of acres in your MLRA? Use Chat Pod to provide your number.
15
What map unit has the highest number of acres in your MLRA? Use Chat Pod to provide your number.
16
Step 1: Run the Pangaea reports No selected set is needed Reports prompt for MLRA
17
Step 2: Components in Excel Export Reports can be sorted using Excel
18
Step 3 Save the results to your PC and import into Excel
19
Step 4 Now sort based on the acres to find Fayette has the greatest number of acres
20
Compare components to benchmark Should the high acre components be benchmark soils?
21
Step 5: Mapunit acres? Well, what about map units? We have reports for that – first formatted
22
Step 6: Formatted Formatted and sorted by name
23
Step 7: Mapunits in Excel Do you want to sort by acres?
24
Step 8 Fayette, 9 to 14 has the highest number of acres
25
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
26
Analyze NASIS Property Data Reporting Physical Properties for a component
27
Analyze NASIS Property Data NASIS reports are available to assist in the location of property voids or identify data population inconsistencies.
28
Analyze NASIS Property Data
29
Analyze Chemical Properties
30
Analyze NASIS Property Data
31
Analyze PSDA Properties
33
Manuscript Review Reviewing map unit descriptions in comparison to NASIS population
34
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
35
Manuscript Review
36
Is it the same mapunit?
48
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?
49
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)
50
What is a SOI-5? The data entry form used to populate the State Soil Survey Database (SSSD)
51
SOI-5 Properties There were 9 SOI-5s written for the Fayette series – this is the first IA0082
52
Interpretations
53
NASIS and the SOI-5 If you want to see the impact that the SOI-5 has on NASIS data you can run review the many new records that have been copied and pasted from the original data. You can then review the deviation in population of the many components
54
NASIS and the SOI-5 Review the ENG data for the IA0082 SIR and you will see slight deviations.
55
Manuscript and NASIS Review Few states have updated NASIS to include manuscript information. Manuscripts and NASIS should be critically reviewed dependent (not independently) of the other
56
Map unit evaluation The map unit concept has been reviewed in several survey areas What other issues should we consider now that you are familiar with the map unit?
57
Analyze Interpretation data Comparison of NASIS interpretations between similar named map units
58
Step 1: Load Data Load by mapunit name
59
Step 2: Run the report MLRA –interp– Interpretation Comparison report
60
Step 3: set parameters Identify the interpretations to compare
61
Step 4: Review report The report identifies the area symbol and musym for each component sorted by musym
62
Step 5: Compare NASIS to Manuscript This is one report of many that will allow comparison of NASIS interpretations to the Manuscript interpretations
63
Correlation Documents Review hard copy reports versus NASIS data
64
Each MLRA should have copies of the correlation documents available in their area.
65
NASIS Correlation Documents Assuming correlation documentation is stored in NASIS, reports are available
66
Analyze NASIS Correlation Data Correlation reports should be reviewed as part of the evaluation process
67
SSURGO Templates Use of SSURGO templates in assessing quality and consistency of data
68
SSURGO Template The SSURGO template is an export of the NASIS data and can be used to rapidly assess the MLRA tailored NASIS data
69
SSURGO Template Data can be rapidly analyzed using the SSURGO template – MLRA Legend
70
SSURGO Template
71
Detailed instructions Detailed instructions on the use of this product is found at: http://soils.usda.gov/technical/access/ http://soils.usda.gov/technical/access/
72
Laboratory Data Review all lab data for the MLRA
73
Available Characterization data The NSSL web site is available to query. Using the Advanced Query page, the MLRA can be used for the query of sites within the specific area
74
Available Characterization data NSSL data is identified and available to download for use in the evaluation
75
NSSL “MO Access Data” Access databases are available on the NSSL sharepoint site https://nrcs.sc.egov.usda.gov/ssra/nssc/ssl/Shared%20Document s/Forms/AllItems.aspx
76
Pedon Review Review of the county TUD, hardcopy pedon data, pedon databases
77
Pedon data in NASIS Load data into NASIS Run the AnalysisPC export report
78
Review of SCS-232
79
AnalysisPC
80
Summary Manuscripts are the foundation of the update. Mapunit concept is found in the manuscript – not NASIS Correlation documents, both hardcopy and NASIS, should be used to understand map unit concepts NASIS is a tool to store data and should be reviewed as part of the correlation process GIS and NASIS data are tools to assist in the evaluation process
