Mapping Soil Borings

The shapefile, borings.shp, represents each core location as a point. The shapefile's attribute data are documented in the table below. After field work is completed, Consultants must contact Dr. Elizabeth Hobbs (651-366-3611 or elizabeth.hobbs@state.mn.us) for unique IDs to assign to the boring logs and GIS records.






Attribute Table Definitions for borings.shp

Field Name Type Length Precision Scale Values

Unique ID for each soil boring within this survey. ID must be in the format yyXXnn where:

yy is the last two digits of the year the core was taken.

XX is the two letter county code (same code used by SHPO)

nn is a sequence number assigned by MnDOT.

For example, the first boring taken in Goodhue County in 2011 would have the ID '11GD01'.
