Splitter: Assertion on very large node id
by Lambertus 03 Mar '16

03 Mar '16

Using an o5m file with a huge node-id seems to break splitter-r427: [..] 3,200,000,000 nodes processed... id=3982721872 3,210,000,000 nodes processed... id=200000782524 Exception in thread "main" java.lang.AssertionError at uk.me.parabola.splitter.O5mMapParser.readNode(O5mMapParser.java:260) at uk.me.parabola.splitter.O5mMapParser.readFile(O5mMapParser.java:187) at uk.me.parabola.splitter.O5mMapParser.parse(O5mMapParser.java:133) at uk.me.parabola.splitter.Main.processOSMFiles(Main.java:1396) at uk.me.parabola.splitter.Main.processMap(Main.java:908) at uk.me.parabola.splitter.Main.calculateAreas(Main.java:599) at uk.me.parabola.splitter.Main.split(Main.java:256) at uk.me.parabola.splitter.Main.start(Main.java:185) at uk.me.parabola.splitter.Main.main(Main.java:155) The o5m file is a combination of a recent planet dump and an address file for France, from here (banco-france-o5m.zip): https://github.com/ligfietser/mkgmap-style-sheets/tree/master/resources It looks like a signed 32 bit integer problem? Splitter is running on Linux x86_64, Java OpenJDK 1.7.0_95 64-bit (mixed mode).

[Patch v1] now option handle-element-version for splitter
by Gerd Petermann 02 Mar '16

02 Mar '16

Hi all, the attached patch adds the option --handle-element-version with three possible values "keep", "fake", and "remove". With "remove" (the default) splitter works like r428, means, the version of OSM elements is not written to the output files, I also did not notice any changes regarding performance. With "keep" splitter writes the version that is found in the input file. With "fake" splitter sets the version to 1. I am not sure what to do when the input file(s) contain elements without (or invalid) version info and option keep is used. Another special case is the pbf format: Since r428 splitter always writes version 1 for nodes, this was a work-around for a problem in the JOSM pbf plugin. This is still done even with --handle-element-version=remove A last special case: with output=xml and --handle-element-version=keep or fake splitter will write api version 0.6 instead of 0.5 A binary based on r428 is available here: http://files.mkgmap.org.uk/download/291/splitter.jar Please let me know what you think about this change.

POIs to areas
by Dave Swarthout 01 Mar '16

01 Mar '16

Hi, I've got a little problem that I need help with. I use the "--add-pois-to-areas" switch when compiling a map. I use a small house icon to represent a building when the tags are building=house or building=home. However, if the building has been entered into OSM as a polygon then my icon is centered inside of it, which is consistent with the "--add-pois-to-areas" switch. What I want is a way to tell mkgmap to skip placing the house icon whenever the building it's describing is an area. Thanks for your help. -- Dave Swarthout Homer, Alaska Chiang Mai, Thailand Travel Blog at http://dswarthout.blogspot.com
