Here is an example of the Cardiff Lars frequency change (UHF) depicted as a graphical Notam....
I agree with IO to some extent, that the airspace depicted here probably contains many errors, but it was free. However, the data is available for free on the web, and it should be possible to keep it updated, ideally through an automated process, again ideally through from the official source. After all, it wouldn't take much for the clever chaps at AIS to generate a KML file from the electronic data they already have. Of course this would become a commercial product and we'd have to pay for it, but I think it'd be pretty good to be able to flight plan a 3D flight, including VNAV, showing 3D airspace, Notams etc.......
The CAA chart is just a section of the Memory Map chart I overlaid onto the map.....just for fun
