GIS Shapefile

The GIS "shapefile" is a set of eight related files including polygons that represent tax accounts. Each record in the shapefile is attributed with a 16-digit parcel number/geographic identifier (GID) and a five- or six-digit property identifier (PID). The shapefile does not include business personal property tax accounts or utility company operating property.


The first six digits in the 16-digit GID indicate the parcel's township, range, and section, with two characters for each. The second set of six digits indicate the approximate centroid of the parcel as an X, Y coordinate within the section, with three-characters each. The final four digits, if other than four zeroes, indicate the auxiliary account reference number.

For example: GID 380330_147320_0000

  • the first six digits represent Township 38 North, Range 03 East, and Section 30
  • the XY coordinates are x147 and y320
  • the last four zeroes indicate that this is a primary account

If an auxiliary account, the GID will end with a number between 0001 and 9999.


The PID is a unique database number assigned to the tax account. In the shapefile, if the record has a PID of zero (0), there is no tax account number assigned as it may be a common parcel, one of unknown ownership, tribal land or, river wash land along the banks of a river.
