**MLRA OFFICE 6 TECHNICAL NOTE NO. 6**

**SUBJECT:** SOI -- Report to Generate Map Unit Descriptions in NASIS

[Purpose:]{.underline} To transmit instructions for populating NASIS and
to run the report to generate map unit descriptions.

[Effective Date:]{.underline} This technical note is effective when
received.

[Background:]{.underline} Numerous excellent map unit generator (MUG)
reports have been created across the nation, each with their own strong
points. The MO6 staff has attempted to compiled some of these strong
points as well as adding new elements to create the NASIS report "6MO
MUG template." This report will be used as a template for all map unit
descriptions generated in NASIS within MO6. The report can be copied and
customized to meet the needs of MLRAs or individual soil survey areas.

[Filing Instructions:]{.underline} File after MLRA Office 6 Technical
Note No. 5. Discard the previous tabulation sheet and insert the current
tabulation sheet.

Because a data element is listed above as used in this report does not
mean you must populate the element. However, the more data that is
populated in NASIS, the more useful the map unit descriptions will be.
Which data are displayed in a map unit description should be driven by
the needs of the users.

Only the data elements used in the report are listed. A complete data
set to generate tables and interpretations requires data entry to many
other data elements. Use the MO6 Instruction 430-386 "NASIS Entry
Guidelines" to identify the complete set of NASIS data elements to
populate.

Use the Word for Windows macro described in MO6 Tech Note no. 5 to
format output from this report.

The MUG report can be copied and modified for use in different MLRAs and
soil survey areas.
