[mkgmap-dev] [Patch v4] drive-on-left/drive-on-right handling

Wed Dec 3 11:42:22 GMT 2014

Hi all,

attached is v4 of the patch.
The drive-on parameter now accepts the following values:
left|right|detect|detect,left|detect,right

- detect is equal to detect,right
- with detect 
all roads are counted to find out whether the map is a drive-on-left or drive-on-right map
- if the detection doesn't return a clear result, the 2nd option is used
- the polish reader only checks the "LeftSideTraffic" string, it doesn't count anything (for now)

@Steve, WanMil:
I've added methods getDriveOnLeft() to MapperBasedMapDataSource
and use it in MapBuilder before a TREFile or NODFile is written
to configure the corresponding flags. 
Classes that are able to detect the dr
I think this is a bit cleaner compared to v3 and to trunk.
