This app is intended to be used as an aid in locating your position relative to the areas displayed on the map. Mapped areas include private oyster ground leases, oyster ground applications, fixed fishing devices, public clamming grounds, and the blue crab sanctuary. The accuracy of your reported location on the map varies due to many factors, but it is generally expected to locate your position within 50 feet of your actual location (for gps equipped devices). This app will work without a cellular or wireless connection. When your device is connected to a network, the app will download our map data every five days to ensure your maps are relatively current even without a network connection; if your phone does have an active network connection the app will use the most current map data we have posted.
