Interactive Maps
Calvert County GIS isn't just for Government. Online maps offer county residents and visitors a variety of tools to find what they need, learn more about what's going on, and virtually explore the natural resources, parks and recreational facilities that make this the place to be. It's also the place to watch the changes in the county's landscape over the past 100 years.

The Calvert County Government collection of interactive, online maps is called MyCalvertMap. These maps come in two versions: "advanced" just for desktop computers, and "lite" which supports all devices including desktops, tablets and smartphones. MyCalvertMap Advanced provides desktop users with tools for measuring, marking up the map and creating scaled, printable maps. MyCalvertMap Lite provides mobile and casual users with a streamlined map that is optimized to work on all devices. 

To use MyCalvertMap Advanced you might need to install the latest version of Microsoft Silverlight plug-in. A PDF viewer such as Adobe Reader is also needed if you'd like to download any printable maps or documents embedded in these maps.

NOTE: MyCalvertMap Advanced works best with Internet Explorer 10 and above and is not compatible with the latest release of Google Chrome. If you're having trouble getting new browser windows to open, disable any pop-up blockers running in your browser. There is a known issue with MyCalvertMap Lite and the Safari browser running within iOS 8 and above that disables certain features of the map. A fix for this issue is being developed and tested.
