Hi Ralf, my understanding is that no device supports the overview map. It is only used on the PC. Why would you want to have it in the gmapsupp? Gerd Ralf Kleineisel wrote
Hi,
is there a way to include the overview map in the gmapsupp.img without having to run mkgmap another time?
If I have, say, three map tiles and the corresponding ovm files:
-rw-r--r-- 1 ralf users 13522944 Feb 17 22:55 10000001.img -rw-r--r-- 1 ralf users 16841216 Feb 17 22:55 10000002.img -rw-r--r-- 1 ralf users 19913728 Feb 17 22:55 10000003.img -rw-r--r-- 1 ralf users 768512 Feb 17 22:55 ovm_10000001.img -rw-r--r-- 1 ralf users 1009152 Feb 17 22:55 ovm_10000002.img -rw-r--r-- 1 ralf users 1336320 Feb 17 22:55 ovm_10000003.img
and I combine all these into a gmapsupp.img, then the overview map is created as a seperate file but not included in the gmapsupp.img:
$ mkgmap --gmapsupp --overview-mapname=OV --overview-mapnumber=99999999 1*img ovm*img
produces:
-rw-r--r-- 1 ralf users 50177024 Feb 20 17:04 gmapsupp.img -rw-r--r-- 1 ralf users 24064 Feb 20 17:04 OV.img -rw-r--r-- 1 ralf users 1132 Feb 20 17:04 OV.tdb
The overview map is not in the gmapsupp.img:

Only after running mkgmap one more time it is included:

It would be very handy to have the overview map in the gmapsupp.img after the first run. Is this possible? _______________________________________________ mkgmap-dev mailing list
