Hi Gerd Can you send me the Mdr16 display of some of the other maps you've been looking at. I'd like to try and find some meaning for bytes 0..2 and the prefix before the level 5 data.

Hi Ticker,
I also thought that some bytes may tells us the uncompressed size or frequencies. I don't see any clear pattern so far...
Some number for the Adria Topo Map: (Mdr 16 length 212) Uncompressed size: 1.582.655 (0x18263e) , compressed: 1029077 (0x0fb3d5) Frequencies of the tree nodes:
'' 0x3 freq: 1 (0x1) '%' 0x25 freq: 1 (0x1) ':' 0x3a freq: 1 (0x1)
