[mkgmap-dev] Family-name trouble when combining *.img to gmapsupp.img

Wed May 5 21:01:32 BST 2010

Hi all,

I created a "public transportation" layer for my map, with rail, bus, 
and ferry routes. I can select the layers in the Settings/Map menu of my 
Edge 705, and the transportation layer is transparent, as it ought to 
be. The only problem is that both layers are called the same in the 
Settings/Map menu.

Here are the commands I used:

* the base map as in http://www.polkupyoraily.net/osm/, 
5 tiles (6324000[12345].img)
  default family-id (42, I assume?), family-name="OSM 5.5.2010"

* the route map, 1 tile (73174273.img)
java -Xmx1024m -jar ../mkgmap.jar --transparent --style=routes --latin1 
--gmapsupp --remove-short-arcs --country-abbr=FIN --country-name=Finland 
--mapname=73174273 --description=routes --family-name=transport 
--family-id=3583 finland.osm

* the combined map (1st try): both maps called "family name"
java -Xmx1024m -jar mkgmap.jar --gmapsupp 73174273.img 6324000*.img

* the combined map (2nd try): both maps called "transport"
java -Xmx1024m -jar mkgmap.jar --gmapsupp --family-name=transport 
73174273.img --family-name=ways 6324000*.img

* the combined map (3rd try): both maps called "ways"
java -Xmx1024m -jar mkgmap.jar --gmapsupp --family-name=ways 
6324000*.img --family-name=transport 73174273.img 

Questions:
1. Why does the 73174273.img appear below the 6324000*.img in the Garmin 
menu? Could the layers be sorted by family-id, that is, 42<3583?
2. Why is the family-name of the *.img not preserved?
3. Even if I enter --family-name twice in the combining step, why will 
both layers get the same name?
