Currently building polygons have names in my area. How do I add the names in the map and enable search? -- cheers, maning ------------------------------------------------------ "Freedom is still the most radical idea of all" -N.Branden wiki: http://esambale.wikispaces.com/ blog: http://epsg4253.wordpress.com/ ------------------------------------------------------

Commit: r1181: Improve estimate of size required for lines and polygons.
by svn commit 09 Sep '09

09 Sep '09

Version 1181 was commited by markb on 2009-09-09 14:56:57 +0100 (Wed, 09 Sep 2009) Improve estimate of size required for lines and polygons. Was underestimating size of lines/polys that would be split due to their number of points.

Smaller Tiles?
by Paul 09 Sep '09

09 Sep '09

I've just updated to the latest mkgmap from trunk and am now having problems processing tiles that I have previously successfully processed. The error I am receiving is java.lang.IllegalStateException: Polygon offset too large at uk.me.parabola.imgfmt.app.trergn.RGNFile.setPolygonPtr(RGNFile.java:179) at uk.me.parabola.imgfmt.app.trergn.Subdivision.startShapes(Subdivision.java:450) at uk.me.parabola.mkgmap.build.MapBuilder.processShapes(MapBuilder.java:868) at uk.me.parabola.mkgmap.build.MapBuilder.makeSubdivision(MapBuilder.java:633) at uk.me.parabola.mkgmap.build.MapBuilder.makeMapAreas(MapBuilder.java:567) at uk.me.parabola.mkgmap.build.MapBuilder.makeMap(MapBuilder.java:174) at uk.me.parabola.mkgmap.main.MapMaker.makeMap(MapMaker.java:96) at uk.me.parabola.mkgmap.main.MapMaker.makeMap(MapMaker.java:61) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:169) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:167) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:636) This is when run against a tile containing only contours. If I regenerate the contours using maxnodes=50000 (rather than the default) then mkgmap finishes but I would prefer to keep them larger if possible and this is obviously changed behaviour if I have previously been able to compile against these tiles. I would say this starting happening within the last 10 commits but can't say exactly when Cheers Paul

Style file not working
by MarkS 08 Sep '09

08 Sep '09

Does anybody know why the following lines style file doesn't work for me: maxspeed > 78 & maxspeed < 82 {set mcssl=50} highway=* & mcssl=50 [0x03 resolution 22] This is the whole file and I get the error: Error in style: Error: (lines:2): Invalid rule file (expr &) Could not open style null The problem seems to be the first line and seems to be related to having maxspeed twice. I then tried the following in the lines file: maxspeed > 78 {set over78=true} over78=true & maxspeed < 82 {set mcssl=50} highway=* & mcssl=50 [0x03 resolution 22] which produced the following error: Error in style: Error: (lines:2): Invalid operation 'g' at top level Could not open style null which seems a very odd error as the only place the file contains a 'g' is in highway. I've tried to debug this using the source code but got nowhere. So if anybody can tell me where I'm going wrong or where to start debugging that would be great. I'm using mkgmap r1165.

does lane assist work with mkgmap maps
by maning sambale 08 Sep '09

08 Sep '09

One user reported that "lane assist" works on my mkgmap generated map. I don't know what lane assist do and not so sure if it works with mkgmap. Anybody here can confirm that this works for newer garmin nuvis? -- cheers, maning ------------------------------------------------------ "Freedom is still the most radical idea of all" -N.Branden wiki: http://esambale.wikispaces.com/ blog: http://epsg4253.wordpress.com/ ------------------------------------------------------

Auto-Merge
by Chris-Hein Lunkhusen 08 Sep '09

08 Sep '09

Hi, does mkgmap auto-merge points which have exactly the same coords? I though the remove-short-arcs option would do this, but last week I found a routing problem on a netherland motorway which was caused by such a double node and the map was created with the remove-short-arcs.... Chris

Missing prompt when joining major road from minor road at an angle
by Steve Hosgood 07 Sep '09

07 Sep '09

Does the IMG file contain markup on junctions to control whether or not a "turn left/right" announcement will occur when you reach it? I've got a case locally where a tertiary road meets a primary road at a shallow approach-angle of about 30 degrees. The Garmin does not announce the junction, not warn of its approach when you're on the tertiary. Coming from the other direction on the primary though, you get an "in 500m, keep right" announcement followed by "keep right" when you're almost at the junction. It would be good to be told to "turn left" when approaching on the tertiary. I can quite understand that if you're approaching a motorway on a motorway_link type of road, then you don't need to be told to join the actual motorway when you get to the merge-point. I wonder if the code that avoids causing an announcement in that case is a bit too eager and does the same for my tertiary-meets-primary situation? Steve

Fixes for subdiv generation and short arc removal committed
by Mark Burton 07 Sep '09

07 Sep '09

Committed a bunch of stuff that improves subdivision generation and removal of short arcs that reach tile boundaries. I've tested it all on GB, NL and PH? tile sets with no problems. Apologies in advance if they break anything. Cheers, Mark

Commit: r1179: Make addAreasToList() less eager to make small areas.
by svn commit 07 Sep '09

07 Sep '09

Version 1179 was commited by markb on 2009-09-07 11:51:09 +0100 (Mon, 07 Sep 2009) Make addAreasToList() less eager to make small areas. Two main changes: 1 - make the test to decide whether an area needs splitting or not more discerning. Specifically, the test to see if the area contains too much stuff now distinguishes between the points, lines and shapes regions. 2 - if the area needs to be split, split into 2 rather than 4.
