then you still face the hassle & expense of scanning the paper chart & cutting it into tiles at various zoom levels.
You can find (on P2P) a whole-UK CAA chart for OziEx, in OZF2 format which already has the various zoom levels.
The free utility IMG2OZF takes in a TIFF, BMP, etc and generates an OZF2 file.
My point was just that MM is a bit of a dead end, especially now that they have gone DRM. It's also never been easy to convert generic graphic images to the QCT format; it's a very long winded procedure.
There isn't a perfect solution but Ozi is probably the most generic way to do GPS moving maps.
As MM move to DRM, more ex-MM maps will find their way onto the P2P scene. Mostly they start life as scanned maps. You need only to find somebody who has done this, once every year, and loads of copy shops have A1 or A0 scanners. I don't know how the 3 maps are stiched together but evidently it works.
