[mkgmap-dev] Processing of mp source

From Mike Baggaley mike at tvage.co.uk on Tue Mar 17 14:29:08 GMT 2020

Regarding the "PROGRAM LICENCED UNDER GPL V2" message, I do not think this
should be in the copyright at all. The copyright statement is about the
copyright of the map, not the program used to build the map. However, the
source code indicates that there have to be at least two copyright messages
or the map does not show up, and this message is only added if there are
less than 2 copyright messages. Something has to be added (or it could exit
saying you must provide a copyright statement). Perhaps some investigation
needed?

I think that if a copyright file is provided, this should override any
existing copyright messages from any input files (i.e. the functionality is
correct now). If you are providing a copyright file, it is up to you to make
sure it contains all messages that are required.

Regards,
Mike

Hi Gerd,

I was looking at wrong places. Actually there is a copyright line from 
mp header.

After patching, option "copyright-file" overrides mp header. Without 
"copyright-file" reappears value from mp. I'm not sure, maybe there 
should be both copyrights present? Dropping a copyright doesn't look proper.

When copyright from mp header is used, is preceded by a line: "PROGRAM 
LICENCED UNDER GPL V2". I guess it is about mkgamp, wouldn't be better 
to put explicit "PROGRAM MKGMAP..." there? Just to make sure, it wasn't 
Mapwel or MapTk ;)

One more question. Does mkgmap correct problems with routing network in 
mp? I mean problems like distance between routing nodes too short, road 
intersects with itself or something like adjusting turn headings.

Andrzej
