Add IGN France baselayers and overlays #463
Comments
What are the usage terms though? E.g. in Germany official maps are often open for private use but not for embedding in map services. I don't see the use case or general demand for admin boundaries, so I would rather not want those. |
Usage is free for any use, including commercial, under the terms of this license : https://www.etalab.gouv.fr/wp-content/uploads/2018/11/open-licence.pdf The license is clear for the data itself but it lacks information specific to web services. How much can you request the service ? (in terms of requests per minutes). I can't find. The Swiss give that information quite clearly here for instance. I will ask for details. |
Have you asked? Not sure that would help much, as we can't really tell or control what our usage would be. |
Yes I asked and it took some time to have this answer. Sorry for the late follow up :
|
Sounds like a lot, we probably won't reach that with a country-specific layer that needs to be configured. What layers should we add? A recent thread was about IGN Scan25 (requires a key) and IGN Plan25. |
I guess the Scan25 layer requires a key. Please provide instructions how to obtain one with a PR or send me a key with private mail. You can prepare an empty entry in keys.template.js and search for usage examples using the names there. |
I'm going to add short names for the map link, cause they're too long for mobile screens, would those be Ok:
|
Yes, those are ok. |
No worries, very minor issue and only in combination with overlays. I think we can close the issue? |
Yes sure 👍 |
Hello,
Since summer 2021, IGN France web services are accessible without key (as it used to be for years).
Lists in french : https://geoservices.ign.fr/services-web-experts
I suggest to add baselayers such as aerial pictures, a base map and an overlay with administrative boundaries. All of those are WMTS tile layers compatible with brouter map display.
The idea comes from a french cyclist requesting a way to add french departments boundaries on BRouter, and using an IGN WMTS layer is a possible solution : https://twitter.com/sylvainavelo/status/1462853551139524615
It will be very much like what has been done for Swisstopo baselayers (#402).
I've seen and I understand the concern about adding non-OSM maps.
I'm working on the issue but will submit the PR only if it meets approval.
