What is MD iMap?

Maryland's Internet Map - MD iMap - is a diverse and flexible “system” that provides a wide variety of products and services to the citizens and government employees in Maryland. It represents a centralized collection of the most commonly used map data, such as roads, streams, place names, government boundaries, property information and detailed imagery.

MD iMap in the News

The new MD iMap Executive Order has been officially signed by the Governor.
