[mkgmap-dev] Problems with r3781

From Gerd Petermann GPetermann_muenchen at hotmail.com on Thu Feb 2 08:45:30 GMT 2017

Hi Ticker,

I did some more tests with r3782, also with other styles like that for openfietsmap.nl (by Minko aka ligfietser)
http://mijndev.openstreetmap.nl/%7Eligfietser/openfietsmap/Scripts/Styles/

I've compared the results with trunk version r3773 and noticed that the branch produces fewer
messages from ShapeMergeFilter like
"ignoring duplicate shape with id 144075839 at http://www.openstreetmap.org/?mlat=54.606792&mlon=8.374727&zoom=17 with type 0x53 for resolution 22"
and in fact the branch writes those duplicated shapes two times while trunk doesn't.
The style adds two equal 0x53 polygons for the way 144075839 , one because it has natural=beach, one because it has surface=sand.
The trunk version seems to filter those duplicated shapes while the branch doesn't.
The result is an increased img size for this style, while the branch typically creates smaller files for the default style.

Do you see why the this happens?

Gerd

Hi Gerd

Fixed this and committed - I think the problem was always there but
excess MapArea splitting made it very unlikely to happen.

There is still a little bit of old logic that I'm not sure about, but
I've removed for now which is safe. Some time I'll think if something
similar needs to be put back
