Thank you, Richard. This seems like exactly what I need.

My only issue with it so far is that the embed function doesn’t work for me. When trying to use it on my WordPress page it only displays the “See full screen” link, but not the map itself (it’s a blank area where it should’ve been).

Here’s the code I use:

<iframe width="100%" height="300px" frameBorder="0" allowfullscreen src="http://umap.openstreetmap.fr/en/map/untitled-map_285394?scaleControl=false&miniMap=false&scrollWheelZoom=false&zoomControl=true&allowEdit=false&moreControl=true&searchControl=false&tilelayersControl=null&embedControl=null&datalayersControl=true&onLoadPanel=caption&captionBar=false&datalayers=748987"></iframe><p><a href="http://umap.openstreetmap.fr/en/map/untitled-map_285394">See full screen</a></p>

Do you know anything about this? If I get it to work, will people be able to annotate the map from the embed? Thanks a lot!
