Dear all,

The new technical documentation for the Federal spatial data infrastructure https://docs.geo.admin.ch is now available. It replaces the previous technical documentation on api3.geo.admin.ch and offers modern, clearly structured access to all information related to the use of the federal geoservices.


Best regards,
Helpdesk federal geoportal

Dear GeoAdmin team,

Thank you for the refreshed documentation, I really like it!

I have 2 minor feedbacks about the web mapping examples:
  • The WMTS OpenLayers example is missing the OpenLayers CSS file, which makes the zoom buttons look a bit funny. I created a forked version on CodePen for comparison, where I added it in Settings => CSS. The XYZ OpenLayers examples also have the same issue.
  • The JS API page recommends using Leaflet or OpenLayers, but as far as I can tell, the docs do not (anymore?) contain a Leaflet example. A (slighly biased*) suggestion would be to add a Leaflet example similar to this example on CodePen to the WMTS examples.
Thank you,

Roman Karavia

*Bias explanation: I am the author of the Leaflet plugin used in the example mentioned above.

Dear Roman

Thanks for your feedback. Indeed the WMTS OpenLayers example had an issue with the CSS - we fixed that following your suggestion.

Adding an example on how to use Leaflet is a good idea as well, we put a reminder for that to our backlog. The team expresses their appreciation for your Leaflet plugin. It’s always motivating to see the community building things based on our services and data.
If you have more feedbacks, ideas or comments, do not hesitate.

Thank you and best regards,
