Road names

Use these state-wide maps for the names and numbers of Interstate, US, and State highways. They also include the names of many local roads.

Use this tool to identify street addresses. MD Dept of Planning recommends Firefox for this mapping application, however Chrome works well too). Under the Contents tab, check Parcel Boundaries and uncheck all other options. Navigate to a property and click it, then click SDAT URL in the popup for the Real Property page. Note that the base map is copyrighted, but an alternate version is available with a base map that is not copyrighted.

Counties and cities

Use these maps for the names of local roads and smaller streets not identified on the state maps. Some also provide house numbers.
