Hi :)

I’m trying to add the vector map from basemap.de as my background map for exports in FME 2026.2. However, I cannot make it work. I used the following link and MVT as my feature reader.
I get an error regarding a missing API key. Has anyone ever used basemap.de as their background map and can tell me if there’s a simpler way to add it (and also be able to crop the data to my AOI before reading all of it, which covers the entire country), or if I need to somehow request an API code to use this map?

Here’s the link (which I am also not sure if it’s the correct one):

Thanks!

Hi everyone, 

I solved this by using the PythonCaller and decoding the map. This was my pipeline in the end:

    Hi ​@bianca_ 
    I have a suggestion that may assist!
    Use the OGC WMS background map source with basemap.de's raster WMS endpoint. In FME Options > Background Maps > "+", select "OGC WMS (Web Map Service)" and enter URL: https://sgx.geodatenzentrum.de/wms_basemapde?. No API key, no authentication needed. 

     

    Let me know if this helps or is what you’re looking for!
