Mapping Resources

Consult the MdMUTCD guide for the correct tags to use when encountering a standard traffic sign in street-level imagery or a field survey.

Maryland's entry in the United States Contributors listing for OpenStreetMap states the following:

All Maryland state GIS data is specifically exempted from having any license under state law. The passed law, Senate Bill 94 (2015) repealed the code that gave governments the authority to compel a citizen to enter into a contract (e.g. a license) before distributing geographic data.

Further, all local and municipal governments within in the State of Maryland are governed by the same law. Therefore, even if a county or local government website lists a license requirement, the license is invalidated by the law. Some local governments have not updated their terms after the passage of this bill.

Per these state guidelines, you are free to utilize any state, county, or municipal government-provided resources (in accordance with OpenStreetMap guidelines). An index of links to Maryland geographic information resources can be found at Maryland/Mapping Resources.
