[mkgmap-dev] mapids beyond the limit

Fri Nov 1 21:53:13 GMT 2019

Hi Gerd

Thanks a lot; will test it when the .jar file is available.

I haven't investigated if the FIDs and PIDs also need to be checked for 
an invalid input.

I've noticed that some house numbers are not found in Mapsource,  reason are missing entries in NET3. So far I've learned that NET3 must contain all roads with numbers. There is also an issue with equally named roads in different cities, but I am not yet sure if I can fix those.
