[mkgmap-dev] Problem with drive-on

Sun Dec 8 09:25:02 GMT 2019

Hi all,

the boundary preprocessor that is used to compile the bounds.zip already contains a check that produces a warning like
"Country name Ohoi RumahDian not in locator config. Country may not be assigned correctly."

I can change the code to print an error instead which would appear in stderr.
For now, I've only changed the behaviour of the --drive-on detection in r4385.
Maybe it would be better to change the java code which sets mkgmap:admin_level2 so that the value is not filled when it is not a known ISO code
and also the CountryISO filter to return null if the 3 character ISO string is not known?

Gerd

Hi Carlos,

I'll have a look at it. I also think about a change regarding the detect method. If I got it right it assumes right hand traffic for countires which do not appear in LocatorConfig.xml. It might better ignore those entries when the majority of roads is in a known country.

I agree it seems admin_level value is wrong. I've added a comment on
changeset aobut it. A warning as you suggest may be useful to detect
such cases.
