I'm trying to resolve the names of streets in Switzerland by geo coordinates using queries like this:

https://api3.geo.admin.ch/rest/services/api/MapServer/identify?mapExtent=0,0,100,100&imageDisplay=100,100,100&tolerance=20&geometryType=esriGeometryPoint&geometry=609586,186670&layers=all:ch.swisstopo.amtliches-strassenverzeichnis&returnGeometry=false

It is working fine but in locations like the one in this example, I would expect it to return the name of the A6 Autobahn. Instead it only reports the Sägebachweg which is running alongside the Autobahn.

Are Autobahnen not included in ch.swisstopo.amtliches-strassenverzeichnis?

Ciao Luzian,

Thank you for your question.

Unfortunately not. If you want to add the names of the Motorways, you have to use ch.astra.nationalstrassenachsen.
Important here: the name of the Motorways is "Nationalstrasse" and not "Autobahn".

Here an example of a possible query:
We hope this can help you.

Best regards,

All axis, meaning the linear elements, do. The reference points do not have the "strassennummer" attribute
