Detailed Project Plan Evaluation. 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 .
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

Reviewing the map units and components within the Project
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
Export Reports can be sorted using Excel
Reporting Physical Properties for a component
NASIS reports are available to assist in the location of property voids or identify data population inconsistencies.
Reviewing map unit descriptions in comparison to NASIS population
Now you have identified map unit and components to be evaluated, next step:
Comparison of NASIS interpretations between similar named map units
Review hard copy reports versus NASIS data
Each MLRA should have copies of the correlation documents available in their area.
Assuming correlation documentation is stored in NASIS, reports are available
Use of SSURGO templates in assessing quality and consistency of data
The SSURGO template is an export of the NASIS data and can be used to rapidly assess the MLRA tailored NASIS data
Data can be rapidly analyzed using the SSURGO template – MLRA Legend
Review all lab data for the MLRA
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
NSSL data is identified and available to download for use in the evaluation
