Level info wrong in mkgmap --help=options
by Garvan 14 Mar '10

14 Mar '10

java -jar mkgmap.jar --help=options reports --levels=levels code Change the way that the levels on the map correspond to the zoom levels in the device. See customisation help. The default is the equivalent of: "0=24, 1=22, 2=21, 3=19, 4=18, 5=16" although this may change. But in the source code I see /src/uk/me/parabola/mkgmap/general/LevelInfo.java public static final String DEFAULT_LEVELS = "0:24, 1:22, 2:20, 3:18, 4:16"; Garvan

mkgmap gives java error
by Tony Groves 13 Mar '10

13 Mar '10

Hello! I got my first GPS recently, a Garmin GPSmap 60CSx, and am now trying to create maps for it via mkgmap, but am having problems. I'm running Debian Lenny, with mkgmap-r1600 (current version) and Sun Java 6. My machine is 32-bit AMD with 2GB memory. I managed OK (using an older mkgmap version) to convert and upload a few small city maps (Dublin, Barcelona, etc.) but can't manage (using either mkgmap version) a bigger map, all of Ireland, which I got from Geofabrik (http://download.geofabrik.de/osm/) The .osm file is 318MB in size. When I run mkgmap (with no options) I get an error, which starts as follows: java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOfRange(Arrays.java:3209) at java.lang.String.<init>(String.java:216) at com.sun.org.apache.xerces.internal.xni.XMLString.toString(XMLString.java:185) at com.sun.org.apache.xerces.internal.util.XMLAttributesImpl.getValue(XMLAttributesImpl.java:537) at com.sun.org.apache.xerces.internal.xinclude.XIncludeHandler.processAttributes(XIncludeHandler.java:2030) at com.sun.org.apache.xerces.internal.xinclude.XIncludeHandler.startElement(XIncludeHandler.java:907) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.scanStartElement(XMLNSDocumentScannerImpl.java:400) I then used splitter (current version) to split the map file, which resulted in a single file being produced, 142MB after unpacking (less than half the size of the original!?), and submitted that to mkgmap, but it bombed out again (though with a different error). Can anybody suggest what I might need to do to get it working? Thanks very much. Tony.

[PATCH v1] - sleep-on-startup
by Mark Burton 13 Mar '10

13 Mar '10

I recently discovered jvisualvm and have been using it to profile mkgmap. One thing I haven't discovered yet is how to profile an application from the start - its trivial to attach to an already running java app using the gui but if it's already running, you could miss some useful info. So, the attached patch is a little kludge that lets you start mkgmap but then it immediately pauses for a little while (long enough to attach jvisualvm to it and turn on the profiling, etc.) before it gets down to work. To use this, just add -Dsleep-on-startup=30 or similar to your Java args. Can anyone think of a better way of achieving the same goal? Mark

how to differentiate road types with zoom levels?
by Minko 12 Mar '10

12 Mar '10

Hi, I was wondering if it is possible to use two different layouts for the same road on different zoom levels. For instance a small 1pix line on lower zoom levels, and a wider 3pix line with dark borders on the highest level. In the TYP file I use 0x00 road for the first, and 0x05 for the second. In the Style file I use: (highway=tertiary | highway=tertiary_link) [0x00 road_class=3 road_speed=3 resolution 23-21 continue] (highway=tertiary | highway=tertiary_link) [0x05 road_class=3 road_speed=3 resolution 24] You can see the result here: http://sites.google.com/site/openfietsmap/zoomlevels The processed map looks cool in Mapsource: thin lines when zoomed out, bigger lines when zoomed in. However, the routing is now messed up (because of the continue statement?) Is there a way to solve this? Another question is how to adjust the road labels, for instance I like to show on the map only the ref. number of the road, like "N224" (without using highway plates) and on the tooltip label if I point it with the mouse, "streetname (ref)" like "Zeisterweg (N224)". Cheers, Minko

Commit: r1600: Add tile file name to NET1 overflow message.
by svn commit 11 Mar '10

11 Mar '10

Version 1600 was commited by markb on 2010-03-11 22:27:52 +0000 (Thu, 11 Mar 2010) Add tile file name to NET1 overflow message. The Logger class keeps track of which file is being processed by each thread so getting that info is easy.

Re: [mkgmap-dev] Re : Lower case letters
by David 10 Mar '10

Hello Daniela, You should be able to do it with the online TYP editor (if you mean http://ati.land.cz/) Doing this with an hex editor is not so trivial, because you will have to add some bytes and then you will have to update new data offsets. If you look at the online editor perl script (which is very good), you will see that is not so easy. Another solution is to try makeTyp. It makes only NT1 TYP and is able to deal with pictures instead of XPM patterns. David

Mapsource problems with moved folders, etc (regedit)
by Daniela Duerbeck 10 Mar '10

10 Mar '10

Hi! The first times I dealed with Openstreetmap maps and mapsource I got often the error that mapsource told me it had problems and needed to be reinstalled. That was due to the fact that I had deleted some folders so mapsource could not find them anymore. ;-) I had to use regedit to delete the items in the registry and everything was fine again. My question is, is there already a web page that explains this procedure? I mean, for me it is OK, I know now what to do, but should we explain it to others that perhaps are not familiar to regedit?
