Commit: r1598: v3 of the patch is taken from r1596.
by svn commit 06 Mar '10

06 Mar '10

Version 1598 was commited by steve on 2010-03-06 13:42:30 +0000 (Sat, 06 Mar 2010) v3 of the patch is taken from r1596. I have slightly modified it compared to v2. Just some minor improvements and the merging to the patches that have been already committed. Summary: Reduce number of cuts in multipolygon processing Reduces the number of cuts performed by multipolygon processing by combining the cut of several polygons in one cut instead of n cuts. This speeds up the processing for multipolygons consisting of lots polygons. WanMil

property boundaries
by Greg Troxel 06 Mar '10

06 Mar '10

I have a shapefile of property boundaries in my town (from MassGIS). It has a bunch of polygons, with metadata about size and lot number (from zoning maps, like R27-7). Eventually I might import this, but I'm going very slow on that and right now I'm trying to work out sensible conversions and garmin rendering. I used polyshp2osm.py and got closed ways with area=yes and some massgis-derived tags. This didn't turn into anything with mkgmap, which is what I expected. What I would like is to have thin lines rendered at the boundaries, and not necessarily anything else. Perhaps having an area to select for information and the lot # would be cool, but far less important. My thoughts are edit polyshp2osm.py to have different tags drop area=yes add boundary=lot # for now, and figure out what later add to mkgmap line style boundary=lot maps to something that shows up and then see how that goes. Any advice?

Commit: r1595: Avoid infinite loops when following roundabout arcs.
by svn commit 05 Mar '10

05 Mar '10

Version 1595 was commited by markb on 2010-03-05 12:29:18 +0000 (Fri, 05 Mar 2010) Avoid infinite loops when following roundabout arcs. The code worked OK for well formed roundabouts but could hang when the roundabout had a "tail". Now, it should not hang no matter how weird the roundabout is.

[PATCH v2] Reduce number of cuts in multipolygon processing
by WanMil 05 Mar '10

05 Mar '10

The patch fixes a NullPointerException (thanks Felix!) which sometimes happened with the first patch. @Marko: I don't know any reason, why this multipolygon patch should trigger your exception. The stacktrace shows that you use a modified Main.java which seems to trigger the Exception. WanMil

Commit: r1596: Stop loops in ways being trashed by the short arc removal process.
by svn commit 05 Mar '10

05 Mar '10

Version 1596 was commited by markb on 2010-03-05 19:40:42 +0000 (Fri, 05 Mar 2010) Stop loops in ways being trashed by the short arc removal process. Previously, when two (directly connected) nodes were merged because they were so close as to be indistinguishable all the points between them were trashed. That's OK for ways that go directly from one node to the other but if the way formed a loop (e.g. a contour line), removing all the points was the wrong thing to do. So now, nodes are not merged (and the points between them are not trashed) if the length of the arc between the nodes is greater than the minimum arc length. Also, reduced code nesting through the use of more "continue" statements.

mkgmap gets stuck on Kosovo
by Felix Hartmann 05 Mar '10

05 Mar '10

When I try to compile Kosovo from Geofabrik, with my style: https://svn.origo.ethz.ch/openmtbmap/ it gets stuck infinitely. Default style passes without problem. I know it's not the style that broken (compiles clean on every geofabrik country but South-America where it gets stuck too, however on index creation), but something only rendered using the style that triggers the bug. mkgmap does not output any error message, simply gets stuck.

Index in gmapsupp
by Nakor 05 Mar '10

05 Mar '10

Hello, I know that mkgmap does not include the index in the gmapsupp file. If you want this you have to use MapSource to build the gmapsupp. Is there any plan for mkgmap to support this? What are the technical limitations that prevents it to do it? Thanks, N.

mkgmap hangs on this type of way
by Peter & Suzie 05 Mar '10

05 Mar '10

I have noticed for the last 2 weeks the mkgmap was hanging but nothing in a the change log jumped out as someting that may have caused it. After some debugging I have tracked it down to ways like: http://www.openstreetmap.org/browse/way/29416921 The debug log shows it stops when it hits one of these, I fixed a few by splitting the way and remove the roundabout tag from the incoming way.

[PATCH] Reduce the resolution of natural=coastline
by Marko Mäkelä 05 Mar '10

05 Mar '10

I would like to commit this patch, to bring natural=coastline to the same level with other water features (natural=water, landuse=reservoir, waterway=river). This patch would reduce the size of the Finland map by about 200 kilobytes and speed up map browsing at low resolution (wide zoom). With this patch, with full map detail on the Edge 705, both natural=water polygons and natural=coastline lines will be displayed at 30km or closer, and disappear at 50km or further. Any objections? Best regards, Marko
