The Nautical Map allows you to display a map for nautical or navigation purpose. A version of this map, with sonar records, allows you to set and display safety depths. You can choose to add a selection of your collected stations (or none, if you want to hide them). You can too specify the size of the map and zoom modes. These options are adjustable right in Weather Station.
These maps display current data in popup boxes when stations are shown.
Refresh occurs when map is refreshed (mainly at page load).
