Open Source JavaScript Mapping Software

OpenSeaMap's goal is to add nautical and tourism information a sailor could be interested in to OSM (OpenStreetMap) and to present it in a pleasing way. Those include beacons, buoys and other seamark and port information.

This Programm gets the Data from Openstreetmap and converts it to an Layerd SVG File for Inkscape. All conversion is don via a stylesheet. Here is defined what schould be shown and how it is displayed. You can get various styled Maps from the same Data with different sytelsheets. The Stylesheets are Javascript files and easy cusomizeable. (You should have a bit knowledge of OSM tags then it will be easyer to understand)
