Empty Tables in NASIS SSURGO Export

Some NASIS sites have had some problems with the SSURGO export. The problem is empty SSURGO tables. The most common reason for empty tables is that the when selecting survey data into the selected set the target table for the select query is not set at correlation. For a SSURGO set the select query target table for Area and load into the selected set a Non-MLRA soil survey area and then run the select query again with the target table set to Correlation.

The SSURGO export will export only correlated mapunits for the survey area. For additional information on exporting NASIS data see NASIS On-line help. In NASIS click on -- Help | Contents | Using NASIS | Exporting NASIS data.
