[mkgmap-dev] Merge maps with mkgmap

Sat Jul 26 18:49:30 BST 2014

Hi,

i am having problem with merging garmin image files that i have generated
from osm. I have also generated a image with contourlines.

I am trying to merge them together, and there is no problem merging them,
but the name of the map changes to "OSM street map" and there is only 1
"layer" or what they should be called, showing in a Garmin GPS unit.

I have merged maps together a lot of times and then i have got like
Countrymap as one option and Contourlines as another option in the map
settings in gps unit. But now i don't get it working, maybe i am missing
something.

I am using this on the country image file:

--latin1 --draw-priority=20 --route --process-destination --process-exits
--drive-on-right --check-roundabouts --road-name-pois --make-poi-index
--adjust-turn-headings --preserve-element-order
--make-opposite-cycleways --remove-ovm-work-files
--location-autofill="bounds, nearest, is_in" --levels="0:24, 1:22, 2:20,
3:18" --overview-levels="4:17, 5:16, 6:15, 7:14, 8:12" --max-jobs=2
--product-id="1" --family-id="355" --mapname="33110000"
--country-name=SWEDEN" --country-abbr="SWE"
--description="Sweden OSM map by Malmis" --series-name="Sweden OSM map"
--area-name="Sweden" --family-name="Sweden OSM" --show-profiles=1 --tdbfile
--gmapsupp  -c template.args

And using this on the contourlines image file:
--draw-priority=30 --transparent --merge-lines --levels="0:24, 1:23, 2:22,
3:20, 4:18" --family-name="Contourlines" --series-name="Contourlines"
--code-page=1252 --latin1 --max-jobs=2 --tdbfile --show-profiles=1
--gmapsupp  --mapname=333 --description=Sweden-Contourlines
--area-name=Sweden contourdir/srtm/*.osm.pbf

then when i merge them i use this:
--gmapsupp contourdir/srtm/gmapsupp.img countrydir/gmapsupp.img
