When controlling today in LSZH, we had multiple people misidentifying taxiways K and H when taxiing to holding point runway 32. We then looked and in the a350 s OIS and in the vatsim radar data (with navigraph linked). there seems to be something wrong or at least not extracted ideally with the taxiway definition.
A350:
Vatsim Radar
In the navigraph (jepesen) charts it is not really visible as the are is not depicted really detailed, but in the swiss aip charts it is quite clearly visible, that H should only be the 45* taxiway and K the vertical one, which it probably also is in the internal definition but with all the connections it is probably extracted in a way that confuses quite a lot of pilots as all the intersections with K are denoted as H as seen in the zoomed data from vatsim radar.
