Hi Ticker, see https://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=3948 https://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=3949 the sortResource.patch reverts these changes. In Mapsource the results are a bit better with your patch. I'll try again with my Oregon later. Gerd

Question on routing difference
by jan meisters 26 Nov '22

26 Nov '22

Hi all, I´m using an altered copy of the OFM style and therefore sometimes compare the results. One routing difference I found I was able to lead back, but the cause I don´t understand at all. My test-route should prefer the small residential „Altengabengäßchen“ over the primary „Viktoriastrasse“. Latest OFM does, my version not since I removed {add bicycle=yes} from this line: highway=path & surface ~ '(paved|asphalt|sett|concrete|paving_stones|paving_stones:30)' & access!=no & access!=private & vehicle!=no { set highway=pedestrian; add bicycle=yes; add motorcar=yes; } But unfortunately there is no path or pedestrian in the test-route, nor is it an option to use one. Anyone has an idea how this path>pedestrian rule could affect routing on residential/primary? Same happens when I replay the change with the original OFM. Up-to-date osm.pbf, route from BC and screenshots are here: https://files.mkgmap.org.uk/download/556/test_route.zip Thanks Jan

Too many icons from tourism=information & information=route_marker
by Gerd Petermann 17 Aug '22

17 Aug '22

Hi all, recently someone mapped lots of nodes like this: https://www.osm.org/node/9842107614 in my area. With the default style they are rendered as an info icon and the text from the operater tag "Wiehengebirgsverband Weser-Ems e.V." which is really useless info. The actual marker is a maybe 10*5 cm black sticker with a white "J", no further information. I think we should change the rule tourism=information [0x4c00 resolution 24] to tourism=information & information!=route_marker [0x4c00 resolution 24] so that these markers are not rendered. Or maybe set mkgmap:label1 to the ref so that they are less prominent? Gerd Gerd

Outlines of states/provinces
by Steven Miller 08 Aug '22

08 Aug '22

I’m new to mkgmap and am still learning the basics. Having said that, I’ve downloaded the US-South sub-region from geofabrik.de and I can see a country dividing line or boundary between the state of Texas and Mexico. It’s a thin grey line. I’d like to know how to create these boundaries. Can anyone provide a brief overview of how to go about this? I know this question demonstrates a real lack of knowledge about how this whole thing works, but I’m learning as I go. Thanks a bunch, for anyone willing to tackle this ;-) Steve Steven Miller srmj71(a)hotmail.com (717) 562-2879

Sea 'bleeding' into land in northern France
by john510185 05 Aug '22

05 Aug '22

Hi Thanks for accepting my request to join. Please see below text of a message I recently posted to talk-gb(a)openstreetmap.org. Hi, I hope someone can help with this. I'm a big fan of OpenMapChest and am amazed by Ben Konrath's lovely maps. There's a slight problem (of the first world type) in that in his map of Western Europe (specifically the Calais tile) the sea appears to have breached the sea wall and the land is inundated with blue! Ben says he can't help because it's due to a bad change someone has made to OSM. There's also something funny further west, around Le Havre. He says the problem will be solved by whoever made the change, but it's persisted now for quite a few iterations of his map. There does appear to be a conflict between his British Isles map and the one for Europe. However, the problem isn't replicated in OsmAnd, or in any of the other Garmin-related maps I use, which would suggest that OSM itself is OK. Any wisdom greatly appreciated! One of the replies I received was as follows: Those maps are generated with mkgmap, and this sort of problem happens occasionally when coastlines get broken in OSM. You might look at the archives for mkgmap-dev(a)lists.mkgmap.org.uk or perhaps post there directly. Any help with this would be much appreciated. I have MapSource screenshots available, but didn't attach them in case I messed anything up! Cheers!

Problem when splitter runs out of disk space
by Mike Baggaley 02 Aug '22

02 Aug '22

I recently had a problem where my disk filled up while running splitter, but splitter did not exit, continuing to run for over an hour before I looked at it and killed the process. I assume it was waiting for something which could never happen. The log file ended with the following: Exception in thread "worker-4" Exception in thread "worker-2" Exception in thread "worker-3" Exception in thread "worker-0" Exception in thread "worker-6" Exception in thread "worker-1" uk.me.parabola.splitter.SplitFailedException: Thread worker-1 failed to write element at uk.me.parabola.splitter.SplitProcessor$OSMWriterWorker.run(SplitProcessor.ja va:421) at java.base/java.lang.Thread.run(Thread.java:829) Caused by: java.io.IOException: There is not enough space on the disk at java.base/java.io.FileOutputStream.writeBytes(Native Method) at java.base/java.io.FileOutputStream.write(FileOutputStream.java:354) at java.base/java.io.BufferedOutputStream.flushBuffer(BufferedOutputStream.java :81) at java.base/java.io.BufferedOutputStream.write(BufferedOutputStream.java:127) at java.base/java.io.ByteArrayOutputStream.writeTo(ByteArrayOutputStream.java:1 87) at uk.me.parabola.splitter.writer.O5mMapWriter.writeDataset(O5mMapWriter.java:2 03) at uk.me.parabola.splitter.writer.O5mMapWriter.write(O5mMapWriter.java:264) at uk.me.parabola.splitter.writer.AbstractOSMWriter.write(AbstractOSMWriter.jav a:88) at uk.me.parabola.splitter.SplitProcessor$OSMWriterWorker.run(SplitProcessor.ja va:417) ... 1 more Exception in thread "worker-5" uk.me.parabola.splitter.SplitFailedException: Thread worker-3 failed to write element at uk.me.parabola.splitter.SplitProcessor$OSMWriterWorker.run(SplitProcessor.ja va:421) at java.base/java.lang.Thread.run(Thread.java:829) Caused by: java.io.IOException: There is not enough space on the disk at java.base/java.io.FileOutputStream.writeBytes(Native Method) at java.base/java.io.FileOutputStream.write(FileOutputStream.java:354) at java.base/java.io.BufferedOutputStream.flushBuffer(BufferedOutputStream.java :81) at java.base/java.io.BufferedOutputStream.write(BufferedOutputStream.java:127) at java.base/java.io.ByteArrayOutputStream.writeTo(ByteArrayOutputStream.java:1 87) at uk.me.parabola.splitter.writer.O5mMapWriter.writeDataset(O5mMapWriter.java:2 03) at uk.me.parabola.splitter.writer.O5mMapWriter.write(O5mMapWriter.java:264) at uk.me.parabola.splitter.writer.AbstractOSMWriter.write(AbstractOSMWriter.jav a:88) at uk.me.parabola.splitter.SplitProcessor$OSMWriterWorker.run(SplitProcessor.ja va:417) ... 1 more uk.me.parabola.splitter.SplitFailedException: Thread worker-2 failed to write element at uk.me.parabola.splitter.SplitProcessor$OSMWriterWorker.run(SplitProcessor.ja va:421) at java.base/java.lang.Thread.run(Thread.java:829) Caused by: java.io.IOException: There is not enough space on the disk at java.base/java.io.FileOutputStream.writeBytes(Native Method) at java.base/java.io.FileOutputStream.write(FileOutputStream.java:354) at java.base/java.io.BufferedOutputStream.flushBuffer(BufferedOutputStream.java :81) Regards, Mike
