[mkgmap-dev] logging improvement

Wed May 19 11:18:39 BST 2021

Hi Gerd,

Please find attached the updated patch. In most cases where ways are
duplicated, the duplicate ways are given a faked id. However, there are 3
places in StyledConverter where the id is copied rather than using a faked
id - in addRoad, splitWayAt and makeCycleWay. I am unsure as to whether this
is intentional or an oversight, so have left the id as it is currently (I
have had to introduce new Way copy constructors to handle this). If these
should also use a faked id, I can update the patch.

I have followed your suggestion of amending the similar arcs code to get rid
of duplicated ways, and using my style file have reduced the number of
similar arcs warnings from about 21000 to about 600 which also results in a
reduction in size of the gmapsupp file. I will be posting this patch
shortly.

Cheers,
Mike

Hi Gerd,

There are lots of pedestrian areas that are relations. Some of these overlap
with adjacent pedestrian areas and produce a warning like:

Similar arcs (generated way) and (generated way) found at
http://www.openstreetmap.org/?mlat=50.728438&mlon=-1.143728&zoom=17

However, don't commit it yet - I have realised that although this fixes most
of the messages, there are some still being displayed as generated way,
presumably because the relation is copied prior to being used. I'm looking
at this now. The above example after the patch displays:

Similar arcs (generated way) and
(http://www.openstreetmap.org/relation/9381074) found at
http://www.openstreetmap.org/?mlat=50.728438&mlon=-1.143728&zoom=17

Cheers,
Mike

Hi Mike,

please help me: In what situation do we create roads from ways which were
created from relations?

Gerd

Hi Gerd,

Please find attached a small patch that changes the logging of RoadDef when
the original element is a relation. Currently it just says "generated way";
with the patch it gives the URL of the relation in the same way as it does
for ways.

Cheers,
Mike
