@Gerd - it worked well, i.e. two map sets are in. I believe the advantage is on performance since once you processed the img contours once, you can reuse. Plus, on my old Nuvi it allowed to just use the contour as a transparent layer on other maps as well. However, it may not be a standard way to build a map... I'll try your suggestion, thanks. *From* Gerd Petermann gpetermann_muenchen at hotmail.com <mkgmap-dev%40lists.mkgmap.org.uk?Subject=Re:%20Re%3A%20%5Bmkgmap-dev%5D%20Maps%20with%20contours%20shows%20two%20maps%20in%20some%0A%09devices%09%28i.e.%20Zumo%20XT%29&In-Reply-To=%3CAM0PR08MB5410680646200A44DA4735E39E850%40AM0PR08MB5410.eurprd08.prod.outlook.com%3E> *on* *Mon Jun 8 10:14:13 BST 2020* Hi Enrico, no idea if a single gmapsupp.img can contain two map sets with different family ids and multiple typ files. Is it important for you that you have the contours in a different map set? If not, I would merge the osm data and the contour data first, use splitter on the merged data to have a single map containing osm data and contours. That's how I create my own maps. The only problem that you have to take care of is that the contour data must not contain ids which overlap the OSM ids. I just noticed that my file Hoehendaten_Freizeitkarte_EUROPE.osm.pbf contains node ids starting with 7.500.000.000, so I have to create or download a new file now.

Hi there.
I create my maps with contours using the following command
java -jar ./mkgmap/mkgmap.jar --description="*$family_name - OSM*" --output-dir="$dest"/ \ --family-id=10030 --product-id=1 --family-name="*$family_name - Map*" --route --remove-short-arcs --bounds=bounds.zip \ --precomp-sea=sea.zip --location-autofill=is_in,nearest --draw-priority=20 --gmapsupp --index --housenumbers "$work"/"$suffix"*osm.pbf ./typ/gspeed.typ \ --family-id=10031 --product-id=1 --family-name="*$family_name - Contours*" --draw-priority=10000 --transparent $contours ./typ/gspeedContours.typ
In blue the part that refers to contours. Mapids for the two sets are different.
On my Garmin Montana I see just one map with the name passed in --description option (*$family_name - OSM*). On an old Garmin Nuvi I see two maps, the real map with streets (named *$family_name - Map*) and the one with contours (named *$family_name - Contours*), which I can enable/disable individually. On the new Garmin Zumo XT I see two maps, both named *$family_name - OSM. *I can't disable just one of the two, they seems to be linked and it is weirs they show up with very same name in the list.
Question: is there a way I can merge the two maps so I get the same behaviour anywhere?
Thanks! Enrico
