I have two maps in basecamp, both from this morning. The openstreetmap.nl Lite installed by the exe file.
I installed the gmapsupp by GMapTool into my c:\garmin\maps\US-Florida directory.
The gmapsupp.img does not contain an Overview map. When you run mkgmap this overview map is only created for the pc version.
Mkgmap will write temporarily ovm_*.img files to create such map. Your mapset.img is empty because the ovm files are not written into the gmapsupp.img. If you have compiled those files, you can install the mapset with mapsettoolkit or run the nsi script with nsis.
Is there a difference between the java-file running under Linux or under Windows?
I make the download of the osm data, splitter of files and run MKgmap on my Linux maschine. Then I start my virtualbox with win10 and use a share dir to access to gmagsupp.img file. I use GMapTool to create a new map directory with the new map in. Then I change to this directory and install the new map.
How to get this ovm_*.img into the map?
You dont have to. Mkgmap will write it into the overview img (20010000.img)
All you need to do is install those index map files on your computer. For Windows I use nsis (you need add nsis as option in your args file).
Or else you can use mapsettoolkit. But I dont know how to do that on Linux.
When I add the osmmap.img to build the new basecamp map it replaced my name by OpenFietsMap(US); This is the family-name: from osm_bnl.args.
I think one problem is solved. The overview map.
But now the light green (light green → hex: d8f7ba) color of map. The contrast on my garmin oregon 450 is not so good, I would prefer the white color from the openstreetmap.nl.
Great that you solved it The rough pattern in the light style is used to make it render faster.
The background is natural=background
In your polygon file this is specified with natural=background [0x010100 resolution 12]
The light style that you prefer is using natural=background [0x010200 resolution 12]
Another option is to edit the polygon 0x010100 in the typ file with typviewer, so you can choose another color.
In the directory ./Styles I have a file polygons
here is only one position with natural=background
When I change this to 0x010200; nothing change in basecamp!
But it is okay! I leave it as it is! I am happy now!
I want to download and test my modification, I made in Openstreetmap.org as soon as possible in basecamp. I am driving with my bike and my garmin and I am looking for the bicycle ways. When it is running under bascamp that is okay. I can download your map later …
I copied 20010.typ to 20011.typ and 20013.typ, that I have no conflict im Basecamp.
I made 3 different Styles directories
./Styles → copy from openstreetmap.nl
./Styles-light → copy from openstreetmap.nl
./Styles10200-> copy from ./Styles
in ./Styles10200 I changed in the file polygons the field natural=background [0x010200 resolution 12]
I use 3 different command lines for:
mkgmap -c template.args --gmapsupp --tdbfile --overview-mapname=osmmap 6324*.osm.pbf -c osm_???.args 200xx.typ
In all my maps there all same light grey fine lines, but not in yours! You can see some in the upper pictures too.
(Blue mark)
The red mark where the water area have differnet sizes, could be arise by the lower resolution from the lite version!
