Parcel Map Description
Pima County GIS parcel maps are generated from the Pima County
and show Pima County parcels and street centerlines.
These maps differ from
Assessor Record Maps maintained by the Pima County Assessor's Office in these ways:
Pima County GIS parcel maps seek to describe physical reality and proposals.
For instance, the maps may show each lot in a mobile home park where the entire park is one legal parcel.
In cases like this, each lot has the entire park's tax code.
Pima County GIS parcel maps show "seamless" parcels. That is, they have been stretched or "rubber-sheeted" where
necessary to ensure connectivity between subdivisions and sections.
The intent is to accurately display parcel and street relationships with minimal sacrifice of dimensional
The resulting maps are good for planning, overlaying other map features, and seeing
the relationships between parcels.
