Hi,

For France, we have in ID the map BDOrtho IGN.

IGN (Institut Géographique National) is a great source of informations : these informations are visible on this site or this one. On the first one, we have satellite views (= the BDOrtho IGN in ID) but also cadastral parcels and IGN plan with a lot of names (for rivers for example). Some of these rivers are visible only on the IGN plan : in Guyane, there are many forests and, on satellite views, rivers are invisible because of the trees.

For USA, I can see that there are USGS satellite views (= "USGS Imagery" in ID) + USGS Topographic Maps.

So I would like to know if it is possible to add the IGN Plan to the maps in ID : I know that you need a key (I try to find a link for the tiles but I have no key). But I think you have one because of the BDOrtho IGN map. So maybe it is easy to add the IGN Plan because you have possibly all for the BDOrtho IGN map.

To be more helpful, maybe you will find some useful informations here and here.

Best regards

I just find something : a direct link to the IGN Plan

@Mahabarata There are two conditions that need to be met. The license / terms-of-use of the data must allow the use for OSM and the data needs to be available in a way that can be used with OSM editors.

I'm not familiar with the IGN data. Maybe @don-vip knows more.

I found these resources, maybe they are of help: https://wiki.openstreetmap.org/wiki/France/IGN_France https://wiki.openstreetmap.org/wiki/FR:Sources_de_donn%C3%A9es_potentielles/France

Thanks for the links. When I follow the first one, in the first part, you have a link to this article. And here you have an official press release from the IGN.

If I translate a little for people who don't speak french, it is written that there are no need of a licence for the "IGN Topo" (which I named the "IGN Plan" in my first post) since January 1, 2021 : the access is now free for everyone.

So the first condition seems ok. For the second condition, I don't know, too technical for me. But with the help links in my first post, I created the link in my second post (I found a link to the BD Ortho, I replaced in this link a part according to what I found in the helps and it gave a link to the IGN Topo). So maybe it's not too hard to transform the BD Ortho we have in ID to an IGN Topo ?

Best regards
