Commit: r1249: Points are numbered across both the point sections and not separately.

Version 1249 was commited by steve on 2009-10-01 23:44:14 +0100 (Thu, 01 Oct 2009) BRANCH: mdr Points are numbered across both the point sections and not separately. This caused all points in subdivisions that had an indexed points section to be incorrect. Searching for points by category should now work pretty well. It is a known problem that points with a subtype of 0 may not be included.

Commit: r1247: When exit is shared between motorways issue warning if none have a ref.
by svn commit 01 Oct '09

Version 1247 was commited by markb on 2009-10-01 09:46:18 +0100 (Thu, 01 Oct 2009) When exit is shared between motorways issue warning if none have a ref. It was warning if any motorway that shared the exit node didn't have a ref but it makes more sense to only warn if none of the motorways have a ref. >From patch by Nakor + further tweaks by me (fixed null exit name in a message)

Should inter tile routing still work when splitting Splitter results again?
by Lambertus 01 Oct '09

01 Oct '09

It's a bit difficult to specify a short topic title for this, so here it goes: Goal: Render the world with tiles that are as large as possible. Problem: If you split e.g. America in large tiles with e.g. 1.400.000 nodes then you end up with a lot of tiles that do not render. If you want everything to render then you need to use 400.000 nodes or so which results in more then 1000 tiles. You can get around this by manually defining the tiles sizes which is what I used to do (or use a density map, but afaik that doesn't work yet). So this time I've done something else: A solution: I created a PHP script that splits America with an high initial node count (of e.g. 1.400.000) and tries to render each resulting tile. If a tile render fails then that area is split again with an ever lower node count until at least two subtiles emerge which are then rendered. This process continues recursively until all tiles are rendered or the node count gets too low and splitting is aborted. The result: Neighboring tiles sometimes overlap because splitter seems to use a little larger bbox for splitting then what the source file contains. You can see the result of this on http://garmin.na1400.info/routable.php The question: Will routing be a problem because the result of recursively splitting and rendering results in tiles that apparently do not line up perfectly? I've done a few tests and it feels that routing has become worse, but I don't have a definitive answer. If so, what can be done about this? I'm curious if anyone (Chris?) has ideas about it. I can provide the script to anyone who's interested. Just send me an email off-list.

Mkgmap appears to hang on some split files
by Lambertus 01 Oct '09

01 Oct '09

While trying to get a new world map update out the door I noticed that Mkgmap sometimes hangs on an OSM data file produced with Splitter. When this happens the CPU is at 100% constantly for hours (e.g. all night) until I kill the process. The problem occurs in r1222 and also r1228. The following command was used for Mkgmap (I know the code-page is redundant): java -Xmx1792M -ea -jar mkgmap.jar --latin1 --code-page=1252 --name-tag-list=name:en,int_name,name --remove-short-arcs --add-pois-to-areas --make-opposite-cycleways --link-pois-to-ways --description='OSM World Routable' --route --series-name='OSM World Routable' Some problematic OSM files are below (created with Splitter r97 and max-nodes=1.200.000): http://planetosm.oxilion.nl/~lambertus/73240155.osm.gz http://planetosm.oxilion.nl/~lambertus/73240185.osm.gz
