Starting with version 1.9.0 mySeaMap will be supporting the myseamap URL scheme. By using this scheme you can launch mySeaMap from other apps or web pages. Here’s an example:
This will bring you to the City Sporthafen Hamburg, displayed with the OpenSeaMap chart type. Chart types are counted from 0 (Apple Streetmap) to 4 (MapQuest) as they are listed in the menu of the app. The parameters zoom (1 to 18) and type are optional parameters.
