custom background polygon in overview map
by Kolesár András 08 Mar '11

Hello, I have noticed that mkgmap creates rectangles in overview map even if maps contain regions with irregular shapes. These are defined as 0x4b background polygons in .mp files. Background polygons were compiled correctly into individual (numbered) .img files, but 0x4a definition areas in overview map did not follow background shapes. I have checked documentation for a setting that enables custom overview shapes, not found. Then I have examined source code, found the algorithm in TdbBuilder.addToOverviewMap() method that creates simple rectangles for overview map. FileInfo reads map bounds from .img file and this gives the rectangle. FileInfo can't read background shape from .img file. I had to find a way for transferring background polygons from MapMaker to TdbBuilder. Modified several (7) files for handling custom background shapes: general/MapDetails.java stores background polygon in a new class variable MapShape background reader/MapperBasedMapDataSource.java returns mapper.getBackground() general/LoadableMapDataSource.java abstract method getBackground(), implemented in MapperBasedMapDataSource main/Main.java holds background shapes for each .img files in HashArray backgrounds main/MapMaker.java fills array Main.backgrounds after finishing file combiners/TdbBuilder.java adds custom background shape to overview map if available reader/overview/OverviewMapDataSource.java assigns more detailed levels for overview map Attached patch file, paths now start with src/ as WanMil asked last time. Patch based on r1846, compiles without errors, works for .mp files. I did not test it for OSM data. Regards, András Kolesár

flooded tiles in nuvi 295W

Hi, I have a user with nuvi 295W. He is having issues with flooded tiles using my map. I never encountered this issue on my device and on mapsource/basecamp/roadtrip. The map has a custom typ file to show land polygon. Are there other users having this issue with nuvi 295W? http://esambale.wikispaces.com/message/view/home/35367350 -- cheers, maning ------------------------------------------------------ "Freedom is still the most radical idea of all" -N.Branden wiki: http://esambale.wikispaces.com/ blog: http://epsg4253.wordpress.com/ ------------------------------------------------------

thanks, it works now with 1885. I had to adapt my script, because the "_OV" was taken from the nsis name. Map are now uninstall-able from add/remove programs - cool!

Commit: r1877: Allow different smoothing parameters for polygons and lines.
by svn commit 07 Mar '11

07 Mar '11

Version 1877 was commited by steve on 2011-03-02 11:17:38 +0000 (Wed, 02 Mar 2011) Allow different smoothing parameters for polygons and lines. It applies the DP filter against polygons with a different agressiveness than for lines. This is really useful because strong DP filter against lines looks really bad, while for polygons the visual quality is degraded less. Implements a new option --reduce-point-density-polygon - Johann Gail Documentation added to the help file - Felix Hartmann

Commit: r1887: Revert the INPUT_CHARSET for the polish files to iso-8859-1
by svn commit 07 Mar '11

07 Mar '11

Version 1887 was commited by steve on 2011-03-07 13:40:14 +0000 (Mon, 07 Mar 2011) Revert the INPUT_CHARSET for the polish files to iso-8859-1 This is essential to the way it works (its basically a trick to avoid converting to using an InputStream). - Andr?\195?\161s Koles?\195?\161r Made the default when there is no codepage parameter utf-8, to retain previous behaviour. This is an extension to the format which does not conflict with correct files I believe.

Commit: r1885: Add srt file to the gmapsupp.img file.
by svn commit 06 Mar '11

06 Mar '11

Version 1885 was commited by steve on 2011-03-06 11:41:56 +0000 (Sun, 06 Mar 2011) Add srt file to the gmapsupp.img file. Needed now that individual tiles use a srt file for all sorting within their sections. We should probably read the required srt file from the tiles, but not entirely clear how that should be done yet.

Hi, do we still use -nsis to activate the creation of the installer? I get these error messages, and no installer: Could not find the installer template. Could not find the license template.
