[mkgmap-dev] Multilayer Map in MapSource?

Thu Dec 17 23:03:05 GMT 2009

I used your templates. This is the first one:

gmapsupp=yes
family-id=1234
product-id=1
family-name=Map1
draw-priority=25
transparent=no
mapname=10000001
input-file=10000001-bayern\10000001.osm.gz
mapname=10000002
input-file=10000001-bayern\10000002.osm.gz
mapname=10000003
input-file=10000001-bayern\10000003.osm.gz
mapname=10000004
input-file=10000001-bayern\10000004.osm.gz
mapname=10000005
input-file=10000001-bayern\10000005.osm.gz
mapname=10000006
input-file=10000001-bayern\10000006.osm.gz
mapname=10000007
input-file=10000001-bayern\10000007.osm.gz

family-id=5678
product-id=1
family-name=Map2
draw-priority=28
transparent=yes
mapname=20000001
input-file=20000001-srtm\20000001.osm.gz

The files were splitted before using the mkgmap splitter.
This is my command line:
java -Xmx3500M -jar ..\mkgmap\mkgmap-r1436\mkgmap.jar -c template.args
The *.img files, gmapsupp.img and osmmap.img are created.

Next step:
gmapsupp=no
tdbfile=yes
family-id=1234
product-id=1
family-name=Map1
mapname=10000001
input-file=10000001.img
mapname=10000002
input-file=10000002.img
mapname=10000003
input-file=10000003.img
mapname=10000004
input-file=10000004.img
mapname=10000005
input-file=10000005.img
mapname=10000006
input-file=10000006.img
mapname=10000007
input-file=10000007.img
mapname=20000001
input-file=20000001.img

and the command line:
java -Xmx3500M -jar ..\mkgmap\mkgmap-r1436\mkgmap.jar -c template-tdb.args

After this being completed, I used MapSetToolKit to install the mapset 
into MapSource. This worked, but I can't see any contour lines. If I 
just render the 20000001-srtm\20000001.osm.gz and install this into 
MapSource, I can see them. My MapSource version is 6.15.7, if that's 
relevant.
