Geospatial Property Data Guide Image

October 10, 2019
The GIS and Mapping Services Division has released the Geospatial Property Data Guide to educate users on the types of property data we maintain and provide on our Open Data site. The guide contains descriptions of property data through a series of tabs, each covering a different data set. You can link directly to the data from its description in each tab. The first version contains tabs for an introduction, parcel identification number (PIN), and parcels. Additional tabs (e.g., easements) will be added as they are completed so be sure to check the guide periodically. Go to the Geospatial Property Data Guide
