[mkgmap-dev] 3byte .typ file support

Sun Nov 2 14:16:11 GMT 2008

Well in the TYP File they are are specified type=0xXXXXX (5digits - 
hexadecimal), however in the map they are specified as Type=0x00 AND 
V2Type=0xXXXXX

You can download free map samples (unlocked) from example here: 
http://www.garmin.com/garmin/cms/site/de/lang/de/wanderkarten (or direct 
link: 
http://www.garminonline.de/allgemein/admin/klick.php?URL=http://www.garmin-download.de/web/topo_de/garmin.exe 
).
Extract the resulting gmapsupp.img with gmaptool (Split files for 
Mapsource).
Have a look at 06701072.img which is the mapfile of Garmisch Partenkirchen.

Here is an extract of a 3byte map in Polish Format (mp), with some 
different examples (how to do this: Open a 3byte .img with Maptk --> 
Tools --> Analyse IMG.
I find the one old POI also pretty interesting, as it shows some fields 
that could be used by mkgmap too. Download Maptk (Freeware) here: 
http://www.maptk.dnsalias.com/

I'm not sure how the DEM is incorporated into these maps (yes they do 
have a DEM, but I don't know how it's used). Maybe the DEM used 
automatically if  a map is 3byte?  The example given on the Spanish blog 
was different, because it had a distinct type. The DEM information can 
definitely be found in the img itself. (I exported a tile of the 
testmap, then again using gmaptool integrated it into mapsource, and the 
only thing inside that gmapsupp.img was the img and the typfile 
(I00002BC.typ). Notice the difference between 3byte objects (type=0x00 
PLUS V2Type=5X and all others. Remember again that all 3byte objects can 
only be seen if used with a typfile. However exported to Polish Format, 
GPSMapedit ( http://www.geopainting.com/en/ )  may see them too.
