Suggestion for more flexibility in locator part of mkgmap
by Clifford Nolan 19 Sep '12

19 Sep '12

Hi Greg, Just to clarify ... the admin_levels for Ireland described here http://wiki.openstreetmap.org/wiki/Ireland/Boundaries#Boundary_Types don't seem to mention things like village boundaries - there's a big gap between admin_level=8 and admin_level=10. In situations like this, maybe the locator could be more flexible and use other kinds of boundaries too. Regards, Cliff

Overview map
by Steve Ratcliffe 19 Jun '12

19 Jun '12

Hi I have started to implement adding features into the overview map. You can find ready built jar files on the download page and in the 'overview' branch in subversion. It creates the overview map from the .img (as before) and so it is very quick to try out even on a set of tiles covering a whole country. There is no configuration yet, it just takes everything (lines and polygons) that is in the least detailed layer of the detailed maps and adds it into the overview. You will immediately notice a big problem in that the overview map shows up even when the detailed maps are being displayed, so you get ugly jagged lines across the top of the map. I remember this happening the last time we has an overview map and I wonder if anyone can remember if there was a solution then? I'm going to start by trying the (so-called) POI flags, as one of those has been noted to be set differently on detail and base maps before. ..Steve

[PATCH v1] Subdivision splitting
by WanMil 28 May '12

28 May '12

Attached patch should fix (all?) subdivision splitting problems. Error like "Area too small to split at ..." cannot occur any more because the way how subdivisions are split is changed. I think it's still not the optimal way but there should be no loss in highly densed areas any more. This is a first patch not ready to commit because there are some performance penalties which can be reduced. But I want you to test the patch before optimization. WanMil

NSIS 64bit installer
by Valeriy Pekarskyy 24 May '12

24 May '12

Hi All! So, the bug is that NSIS generates installers that work only at 32bit Windows systems (can anyone confirm?), so I developed a patch for latest version of mkgmap which includes changes to default nsi script and NsisBuilder.java. Can anyone look through? The main difference is that Registry path should be changed if that is x64. Patch link: http://dl.dropbox.com/u/11265861/nsis.patch or http://pastebin.com/pwnptH27 Best Regards, Larry0ua

Preprocessor for style files
by toc-rox 24 Feb '12

24 Feb '12

My style file are becoming more and more complex. IMHO a (simple) preprocessor would be very helpful. Important features (analogue C preprocessor): - ##include (includes a text file) - ##define (defines a preprocessor var; also as command line option) - ##ifdef (checks if a preprocessor var is defined) - ##else (else for ##ifdef) - ##endif (end of ##ifdef) A simple example (for polygons): ##define BASECAMP ... ##include "indexrules.txt" ... ##ifdef BASECAMP # draw buildings building = * [0x13 resolution 20] ##endif ... Questions: - What do think of this proposal ? - Does anyone already uses an external preprocessor for the style files ?

Commit: r2109: Refactor the default style a little.
by svn commit 07 Feb '12

07 Feb '12

Version 2109 was commited by marko on 2011-11-23 14:50:49 +0000 (Wed, 23 Nov 2011) Refactor the default style a little. Create some substyles and import them in the default style. The default style should remain functionally equivalent. contours_ft: Elevation contour lines, meters converted to feet. waters: Lakes, seas, reservoirs, waterways. landuse: Most other landuse than waters and man-made features. This is work in progress. More substyles will be refactored soon.

[PATCH] Use Apache Ivy to fetch dependencies, put them in dist
by Richard Hansen 06 Feb '12

06 Feb '12

Hi all, Attached is a first attempt at tweaking the build system to automatically fetch the pbf, junit, and macker dependencies as needed. The pbf dependencies are placed in dist/lib so that users can simply run dist/mkgmap.jar after building. Much of the code was adapted from osmosis's build system. It uses Apache Ivy to resolve and download dependencies. Unfortunately, osmpbf.jar has not yet been published to the Maven Central Repository, so it can't be automatically downloaded (easily). This patch assumes that the jar is checked in to the mkgmap svn repository. Any feedback would be appreciated. Thanks, Richard

Hint regarding creation of bnd files with mkgmap
by GerdP 01 Feb '12

01 Feb '12

Hi, if you plan to use the --createboundsfile parameter to create your own precompiled boundary data, I suggest to use it with an empty target directory (default is bounds). Reason: mkgmap will create new *.bnd files for the data given in the input file, but it will "rework" all (!) *.bnd files that are found in the target directory. This rework process is very time consuming and it will fail if your target directory contains corrupted bnd files that are not overwritten in the first step. I don't know if this was intended?

Hi all, for a few tiles I have the problem that the tile is filled with unwanted data: The problem: http://gis.19327.n5.nabble.com/file/n5444194/Screenshot_20120131_112548.png On a larger map it's ok: http://gis.19327.n5.nabble.com/file/n5444194/Screenshot_20120131_112622.png Any ideas ?
