Hi everybody,

I am trying to extract only african roads data from a planet.osm.bz2 2013 file. I used Osmosis and, with the coordinates found on openstreetmap, entered :

osmosis --read-xml file="planet.osm.bz2" --bounding-box top=37.58 left=-18.11 bottom=-35.46 right=54.14 --write-xml file="africaroads.osm"

Here is what I get :

C:\Users\Users\Documents\osm test>osmosis --read-xml file="planet.osm.bz2" --bou nding-box top=37.58 left=-18.11 bottom=-35.46 right=54.14 --write-xml file="afri caroads.osm" juil. 03, 2018 3:54:47 PM org.openstreetmap.osmosis.core.Osmosis run INFOS: Osmosis Version 0.46 juil. 03, 2018 3:54:47 PM org.openstreetmap.osmosis.core.Osmosis run INFOS: Preparing pipeline. juil. 03, 2018 3:54:47 PM org.openstreetmap.osmosis.core.Osmosis run INFOS: Launching pipeline execution. juil. 03, 2018 3:54:47 PM org.openstreetmap.osmosis.core.Osmosis run INFOS: Pipeline executing, waiting for completion. juil. 03, 2018 3:54:48 PM org.openstreetmap.osmosis.core.pipeline.common.ActiveT askManager waitForCompletion GRAVE: Thread for task 1-read-xml failed org.openstreetmap.osmosis.core.OsmosisRuntimeException: Unable to parse xml file planet.osm.bz2. publicId=(null), systemId=(null), lineNumber=3959, columnNumbe r=127. at org.openstreetmap.osmosis.xml.v0_6.XmlReader.run(XmlReader.java:100) at java.lang.Thread.run(Unknown Source) Caused by: org.xml.sax.SAXParseException; lineNumber: 3959; columnNumber: 127; X ML document structures must start and end within the same entity. at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Un known Source) at org.apache.xerces.util.ErrorHandlerWrapper.fatalError(Unknown Source)

Do you have any idea how I can fix this ? thanks in advance

I'd actually start from an extract of Africa from e.g. Geofabrik.

Hello,

Given that osmosis is failing out of the gate, and that the error message seems to indicate a difficulty parsing the xml, I guess that the error has to do with the --read-xml portion. Try adding the compressionMethod option to the --read-xml statement. So for a .bz2 file it would be --read-xml -compressionMethod=bzip2

See if that helps, and good luck!

These days I tend to use osmium-tool instead of osmosis. And I would recommend to use the pbf file instead of the xml one in any case.

A comparable commandline would thus look like this: osmium extract -b -18.11-35.46 54.14 37.58 planet.osm.pbf -o africaroads.pbf -v
