You can include OpenSeaMap in various ways to the website:
Inhaltsverzeichnis
Embed as Static Map
The easiest way you show a static image, and link it with the full map of OpenSeaMap:
- Search in OpenSeaMap the appropriate map section
- Press the key
Print
, so you copy the whole screen
with the key combination<Alt-Print>
you can selectively copy the currently active window - Open an image editing program of your choice and add the screenshot with
<Strg-v>
- Draw the desired information (text, lines, circles, areas)
- Save the image on your computer
- Load the image to your Web server
- Include the uploaded image in the article:
<img src="Path/Filename_of_Image" alt="Alternative_text" width="Width" height="Height">
- Link a static map to the full screen map
<imagemap> Image:MapFullscreen.png|right|200px|mit Link zur Vollbildkarte default [1] desc none </imagemap>
You can link the map directly to OpenSeaMap. So by clicking on the map you opens the fullscreen map of OpenSeaMap in a new window. There you can zoom and move freely:
- Search in OpenSeaMap the appropriate map section
- Copy the permalink (on the map bottom right) by
<Ctrl-c>
- Add the full permalink to your code by
<Strg-v>
<a href="Permalink">
<img src="Path/Fileame_of_Image" alt="Alternative text" width="Width" height="Height">
</a>
Example:
<a href="http://www.openseamap.org/map/?zoom=18&lat=54.18171&lon=12.08555&layers=B0FTT&lang=de">
<img src="../MapFullscreen.png" alt="show 'Teepott Warnemünde' to the chart" width="200" height="133">
</a>
Embed as Slippy-Map
Du kannst OpenSeaMap auch dynamisch auf der Website einbinden. Der Benutzer sieht beim ersten Laden den von Dir ausgewählten Ausschnitt in entsprechender Zoomstufe. Darin kann er beliebig zoomen und verschieben.
You can embed OpenSeaMap also dynamically on the site. Users will see your chosen section and the appropriate zoom level in the first load. He can zoom and move freely.
<iframe width="425" height="350" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="http://www.openseamap.org/export/embed.html?bbox=-2.01,43.15,13.85,53.35&layer=mapnik" style="border: 1px solid black"></iframe>
<a href="http://www.openseamap.org/?lat=48.25&lon=5.92&zoom=5&layers=B000FTFT">Größere Karte anzeigen</a>
The yellow-marked values of the variables have the following meaning:
width | With of the chart (pixel) |
height | Height of the chart (pixel) |
bbox | "Bounding-Box" (the 4 corners of the selected chart) |
lat | Latitude of the chart center |
lat | Longitude of the chart center |
zoom | Zoomlevel of the chart (4...18) |

Tile-Server
The OpenSeaMap tile server is accessible at this URL:
http://tiles.openseamap.org/seamark/
- Seamark-Layer
The seamark-layer is added with the following lines:
var layer_seamark = new OpenLayers.Layer.TMS ( "seamark", "http://tiles.openseamap.org/seamark/", { numZoomLevels: 18, type: 'png', getURL:getTileURL, isBaseLayer:false, displayOutsideMaxExtent:true }); map.addLayer(layer_seamark);
in Drupal
In the Drupal-Center-Forum you can find some solutions with MappingKit:
in Typo3
In TYPO3 Extension Repository you will find 2 extensions:
- rb_osmsimple (own records for markers)
- ods_osm (Coordinates in fe_users and tt_address records)
