Welcome to MDP’s Property Map and Data Products

The Maryland Department of Planning (MDP) annually updates the more than 2,800 property maps, or tax maps, for Maryland’s 23 counties − Baltimore City maintains its own property maps. MDP distributes these maps to the public in electronic DVD format, online or as paper tax maps and digital map images with no included data.

Maryland’s tax maps are updated and maintained electronically as part of MDP’s Geographic Information Systems (GIS) database. The tax maps are then combined with recent parcel information from the Maryland State Department of Assessments and Taxation as individual parcel records are linked to their property locations on the tax maps.

Tax Maps, Parcel data, Computer Assisted Mass Appraisal (CAMA) data, recent Sale data and associated layers including aerial imagery, ZIP code boundary files, land use/land cover data, census geography and census demographic data, Priority Funding Area (PFA) designations, legislative and congressional district boundary files, flood plain data, generalized zoning designations, protected land boundaries, sewer service area boundaries and (except for FINDER Online) residential Sales x,y point files for CY dating back to 2002 derived from the SDAT parcel data are available through MDP as:

• MdProperty View DVDs
• FINDER DVDs
• FINDER Online

Copies of the tax maps with no associated data or map layers, are available through MDP as:

• Paper or Digital Tax Maps

About MdProperty View DVDs

MdProperty View is a visually accessible dataset that allows you to interact with a jurisdiction's property map and parcel information using the advanced features of ESRI's latest geographic information systems (GIS) software, ArcGIS® 10.x*. Simple and easy-to-use search tools help you zoom in to an area of interest on a property map and display your parcel record of interest.

Working geographically helps you understand the relationships between parcel data and the forces that drive your organization so you can make better decisions, identify opportunities and solve problems faster. MdProperty View facilitates geocoding that allows you to match your own customer and client address database records to the MdProperty View parcel points and to display your data on a map.

About Tax Maps

Tax maps, also known as assessment maps, property maps or parcel maps, are a graphic representation of real property showing and defining individual property boundaries in relationship to contiguous real property. The primary purpose of these maps is to help State tax assessors locate properties for assessments and taxation purposes. Tax maps are also used by federal, State and local government agencies as well as private sector firms for a variety of analyses and decision making processes.

The Property Mapping Section, part of the Maryland Department of Planning's Planning Data Services (PDS) division, is responsible for maintaining electronic tax maps and generating paper tax maps for the 23 counties in Maryland. MDP does not maintain tax maps for Baltimore City. The State's more than 2800 county tax maps are managed in a Geographical Information System (GIS) environment and updated annually using new property plats and deed changes obtained from the State Department of Assessments and Taxation (SDAT). The electronic tax maps form the foundation for many of MDP's products and services, including MdProperty View, FINDER and FINDER Online.

MDP’s Property Mapping Section has maintained tax maps for the Maryland State Department of Assessments and Taxation since 1996. New parcels and subdivision lots are added every year to each county set of tax maps, and each property in a county is linked to its corresponding SDAT assessments database record during the annual update cycle. In recent years, the Property Mapping Section has worked to improve the overall quality of the tax maps by using data registered to large scale aerial photography.
