Maryland Signals on the Map

Google Earth users can download the GIS version of Signal Plan Locator and view it as a map along with other geo-coded information. Once the file is open, you will notice the signals are sorted by county. You may access the plans for each signal by either clicking on the signal icon or the corresponding item on the left. A pop-up window will appear on the map with a link to the plans (if they are available for that location). Please note: you may have to adjust the settings in Google Earth if you would like the plans to open in a separate window. We will post a new version of this file with every update.
