The
county coordinate zone identifier number from The Minnesota County Coordinate
System, A User's Handbook by Ken Whitehorn, Itasca Co. Surveyor,
published by Precision Measuring Systems, 1998.
Note: Some coordinate zones include multiple counties and some
large counties have multiple coordinate zones.
Note: These coordinate IDs are not the same as county
IDs.
Note: A list of the codes is available in the DataLogr
