About this dataset
This is a comprehensive point theme that incorporates parcel ownership and address information, parcel valuation information and basic information about the land and structure(s) associated with a given tax assessment account. Data for the Parcel point theme are obtained from the State Department of Assessments and Taxation with added data from Maryland Department of Planning.
The date the point was most recently published in Planning's data products MdProperty View and FINDER Quantum is contained in the mdpvdate field. The date of the most recent Assessments data linkage to MdProperty View/FINDER Quantum points is contained in the sdatdate field. Accounts deleted between those two dates are no longer represented as points.
For more information on the attribute definitions please see the MdProperty View User's Guide, available for download at https://planning.maryland.gov/Pages/OurProducts/DownloadFiles.aspx. **Please Note: Due to the extensive size of the parcel points file, download is recommended from the REST endpoint (https://geodata.md.gov/imap/rest/services/PlanningCadastre/MD_PropertyData/MapServer/exts/MDiMapDataDownload/customLayers/0)**
