Well, Nav Data Service Provider LIDO is a LH-Subsidiary.
However they didn't provide any route or airport documenrtation services until after the take over of some ex-Swissair Departments in the wakes of the collpase of SR (2002?).
Since then they operate under the name of LIDO Zurich and supply our entire route manual. Unfortunately there seem to be some specification issues, since the Charts provided for other customers (LX for example) contain far more information than ours (even some of the info mentioned above).
