how to get address from coordinates

[Hassler Energia]

Hi,

is there a possibility to extract the address out of coordinates? The coordinates (spacial reference) are present in WGS84, for example 9.42385, 46.60447.

How can I get the address of this specific point? Do I need to transfer the lat/lon into LV95 odr LV03 first?

Hi,

You should be able to get this information by requesting the layer ch.swisstopo.amtliches-gebaeudeadressverzeichnis

with a request that looks something like https://api3.geo.admin.ch/rest/services/ech/MapServer/identify?layers=all:ch.swisstopo.amtliches-gebaeudeadressverzeichnis&sr=4326&geometry=9.42385,46.60447&mapExtent=5.96,45.82,10.49,47.81&imageDisplay=100,100,96&geometryFormat=geojson&geometryType=esriGeometryPoint&tolerance=10&returnGeometry=true

You can then change the geometry param to match the coordinates you want.

In this request I've used the global LV95 extent expressed in EPSG:4326 in the param mapExtent, it should work in most cases, but if you need something more precise, that's maybe where to look at first.

Cheers,

Pascal
