OpenLinkMap layer in FacilMap

Posted by Candid Dauth on 4 January 2011 in English (English).

With FacilMap (, Wiki), I try to create a map that has all the features of Google Maps but uses OpenStreetMap layers.

For a long time, I’ve wanted to implement something similar to the relatively new Google Maps feature where you can click on POIs (such as companies or restaurants) and a popup displaying details opens.

Now I’ve come accross OpenLinkMap (, Wiki), which seems to do exactly this. So I’ve created an OpenLayers layer for it and added it to the Beta version of FacilMap available on On zoom levels >= 13, you’ll see these transparent dark-blue circles around some POIs. Click on them and a popup appears with some information about the POI.

At the moment, OpenLinkMap seems to only contain POIs that have either a telephone number, a website or a Wikipedia article. Hopefully, in the future other POIs will be included as well so that one can see their address and opening hours.

If you want to include the OpenLinkMap layer into your OpenLayers map, include the FacilMap API JavaScript into your website:
<script type="text/javascript" src=""></script>
(Once the OpenLinkMap layer is considered stable, it will be added to the stable FacilMap API on

Then add the layer to your map using the following code:
map.addLayer(new FacilMap.Layer.Markers.OpenLinkMap("OpenLinkMap"));

This feature is documented on

This would be really cool if we had this feature in OSM! If only i had some programming experience, then i'd be able to help you.

Awesome ! Please continue this effort, it brings a big additional value to OSM. Just wondering, do you think it would be possible to have a rule mechanis (like the style sheets for the map) to determine what to print in the bubles and how to print it ?

This is something that you have to suggest to the author of OpenLinkMap, as I am only using its data.

Not being able to clic on POI (and also easy routing) is the only reason I don't use OSM for my daily map use. Please improve that and include it on the main OSM map !

Wow! This is very cool! Congratulations.

This must be in on the main page (once it's stable). together with routing, it's just what I miss on the main page.

Very nice, please consider an overlay for marine use. Such as OpenSeaMap.
