[PATCH v5] - drive on left + roundabout direction checking
by Mark Burton 28 Oct '09

28 Oct '09

v5 - added --check-roundabouts option to explicitly enabled roundabout checking/reversing. Not had much feedback on this yet, anyone (apart from Dermot) tried it? Even if you don't drive on the left (almost the whole world?) you may care to try out the roundabout checking. About 3% of all the GB roundabouts had the incorrect direction (plus a lot of other problems that would break the routing). ------------ v4 - improved quality of direction detection ------------ v3 - now reverses the order of the points in roundabouts that have the wrong direction so that routing is more likely to succeed. ------------ v2 - now prints OSM URL of first point in dodgy roundabout. ------------ As suggested, moved from rhd to dol. Two options are now available --drive-on-left and --drive-on-right. By default, you should not have to specify either because mkgmap now determines the side of the road to drive on from the direction of the first roundabout it processes. But if you don't like its choice, you can specify one of these options to override it. Also, it now issues a warning for each roundabout it finds that appears to go in the wrong direction. I just got 720 warnings when I processed the GB map so either there is a problem with the code or there is a lot of duff roundabouts. I checked a handful of them and they were all wrong. Please give it a go and if you find any of the warnings to be wrong, please post the OSM URL of the roundabout in question. Mark

Combination of --generate-sea and --remove-short-arcs flooded Iceland between 25th and 26th October
by Ævar Arnfjörð Bjarmason 27 Oct '09

The map I generate of Iceland with mkgmap and --genarate-sea and --remove-short-arcs got flooded between 25th ond 26th October. If I just use the --generate-sea option the map is not --remove-short-arcs I get a lot of RoadNetwork warnings but the map is not flooded. Here are the two .osm files: http://osm.nix.is/archive/2009-10-25/Iceland.osm.bz2 http://osm.nix.is/archive/2009-10-26/Iceland.osm.bz2 Generated .img files: http://osm.nix.is/archive/2009-10-25/default/13314531.img http://osm.nix.is/archive/2009-10-26/default/13314531.img osmdiff report between the two: http://osm.nix.is/diff/archive/2009-10-26/01-day.html http://osm.nix.is/diff/archive/2009-10-26/01-day.png To reproduce this on the latest file just do: wget http://osm.nix.is/latest/Iceland.osm.bz2 bzip2 -d Iceland.osm.bz2 # Generates flooded map mkgmap --generate-sea --remove-short-arcs Iceland.osm # Map is not flooded mkgmap --generate-sea Iceland.osm

One more error message
by Marko Mäkelä 27 Oct '09

Hi Mark, The error message WARNING (RestrictionRelation): Turn restriction 113509 unknown member role '' lacks coordinates. It could get a position from a participating node or way, couldn't it? Failing that, it could at least display the URL http://www.openstreetmap.org/browse/relation/113509, couldn't it? Best regards, Marko

Sea ploygon problem
by David 27 Oct '09

27 Oct '09

To Christian Gawron, Hello, I tried to generate the sea for Ireland with geofabrik file and it does not work as expected. For example, small islands in the Clew Bay are not well rendered (in the north of Connemera on west coast). Some islands are filled with a sea polygon, but what it may be new for you, it depends on zoom level (I tested it with Mapsource). David

Re: [mkgmap-dev] mkgmap splitter --resolution broken?
by David 27 Oct '09

To Felix Hartmann Resolution 24 contains the most detailed leveol of details you can use in a map. Resolution 23 is a bit less detailed, and so on. That is why resolution 13 contains far less data than resolution 16. But if you mean by "24-13" all resolutions included in the interval [24;13], it is probably a bug.

Commit: r1326: The option that was called overview-description is shown in
by svn commit 27 Oct '09

27 Oct '09

Version 1326 was commited by steve on 2009-10-27 12:42:53 +0000 (Tue, 27 Oct 2009) BRANCH: mapset The option that was called overview-description is shown in mapsource under a column called 'Area'. The same value is placed in the mps file in the location that was called area-name. So I am removing overview-description (which was never documented anyway) and using area-name instead.

Commit: r1325: Correct the map set block.
by svn commit 27 Oct '09

27 Oct '09

Version 1325 was commited by steve on 2009-10-27 11:49:25 +0000 (Tue, 27 Oct 2009) BRANCH: mapset Correct the map set block. There is one value in this block and this item is the only thing that does not come from the tdb or overview map. So I have added a new option --mapset-name for this. In mapsource there is a field you can fill in before sending to the device labeled Map Set Name. This is the same thing.
