Hi, yes you are right, this is a splitter problem which is already known. As you can see in your example, the lake is split in a way that requires it to be split more than once along the bounding rectangle. see : http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2011q3/012119.html and http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2011q3/012120.html This prob. may occur, when the polygon to be split has more than two intersections with the bounding rectangle and consists of some ways that have all their nodes outside the clipping rectangle. As lakes and riverbanks may have curved outlines this can occasionally occur when the bounding rectangle intersects the polygon in a way such that the clipped polygon falls into more than one (or probably two) parts. I usually take the following manual procedure to circumvent the problem when it occurs. 1. Run Tile splitter once and create a map 2. check the map for floodings along large riverbanks or lakes 3. edit the file areas.list (back up the original one createt by splitter) in order to move the border of the tiles away from the offending riverbank or lake. But take care: you have to modify the corner coordinates of at least two areas in a consistent way in order to get a map without holes The modification of the coordinates should be done in multiples of 0x800. 3a. If needed you can visualize the splitting rectangles when you use the --write-kml option in step 1 paste the complete contents of the generated kml-file here: http://display-kml.appspot.com/ 4. rerun splitter using the option --split-file=<edited areas.list> 5. I use the same edited areas.list later again after I have downloaded new OSM-data so this manual procedure has to be done only once for a certain area Maybe someone has enough time to enhance TileSpltter, I unfortunately don't have at the moment. But anyhow: All those working on splitter and mkgmap are doing a great job. Thank you! Wolfgang Am 11.03.2012 22:16, schrieb Martin:
Looks like a coastline-problem. Which parameter you use for mkgmap?

Hi Matteo,
can you please describe the problem and what it is that makes you believe that this is a splitter problem?

Hi, I noticed a problem splitting the geofabrik pbf extract of Italy using the standard splitter-r200 options.
The area is at http://osm.org/go/0CmXpRz , and at http://www.gomatteo.net/10.jpg you can see how it look in QlandkarteGT.
The osm data seem ok, is a splitter problem? _______________________________________________ mkgmap-dev mailing list mkgmap-dev@.org http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
