Dot in --overview-mapname parameter disables search in Mapsource
by Paulo Carvalho 22 Jun '14

22 Jun '14

Greetings, Recently I stumbled upon a problem that left me scratching my head for a while. Search in Mapsource wasn't being enabled while it worked fine for the gmapsupp.img in GPS. The _mdr file was several MBs size, so indexing was obviously taking place. After tweaking the build/deploy script, I found that an extra dot in the overview file names was the cause. The extra dot is due to my particular naming convetion following this pattern: <family name><MM>.<DD>.img MM and DD are the month and day of build. Of course this was simple to fix. I just changed my build script. But I think an error or warning could be thrown by mkgmap or at least a notice in mkgmap options help page so others can avoid this pitfall. all the best and great work, Paulo Carvalho

[Patch v1] improve multipolygon throughput
by GerdP 21 Jun '14

21 Jun '14

Hi all, while looking at the boundary preprocessor code I found a nice improvement for the multipolygon code. Some mp relations contain many small polygons which are added to one java area. This works much faster when the small polygons come first. I've committed the patch in the new bounds branch which also contains other improvements. @WanMil: With this patch, the calculation of complex boundary relations is ~ 4.5 times faster. I've tested this with the old version of the south-america boundaries: r3303 reqired ~ 2774 secs, r3304 612 secs Do you see any possible problems?

Nursing in the waterpark

Hi, why do we map amenity=nursing_home and leisure=water_park to the same Garmin element in default-style? points: amenity=nursing_home [0x2b04 resolution 24] leisure=water_park [0x2b04 resolution 24] Chris

Bad performance because of complex boundary relation
by Gerd Petermann 17 Jun '14

17 Jun '14

Hi, this might be an OSM problem... While working on a "beautifyRoundabout" algo I wondered why one tile in Southamerica needed a very long time to calculate. It turned out to be a problem in the location hook. The boundary relation 1981462 is a very complex polygon. I don't see a simple solution in mkgmap, but wouldn't it be better to create a simple way enclosing the area to map this boundary? Gerd

This is now handled correctly. Sample: http://www.openstreetmap.org/way/8104544
