Hello I have downloaded europe.osm.bz2 and I would like to exctract a large area using osmosis. Please forgive me for my ignorance, I am not a Linux / Unix at all and if I am missing something obvious, please advise.

I am ammending this script I found on the http://wiki.openstreetmap.org/wiki/Osmosis#Extracting_bounding_boxes.

Published script:

 bzcat downloaded.osm.bz2 | osmosis\
  --read-xml enableDateParsing=no file=/dev/stdin\
  --bounding-box top=49.5138 left=10.9351 bottom=49.3866 right=11.201 --write-xml file=-\
  | bzip2 > extracted.osm.bz2

My ammended script:

 bzcat.exe "I:\europe.osm.bz2" | osmosis.bat\
  --read-xml enableDateParsing=no file=CONIN$\
  --bounding-box top=51.2 left=11.7 bottom=47.6 right=23.0 --write-xml file=-\
  | bzip2 > "I:\czechoslovakia.osm.bz2"

Quite frankly I do not even know what the symbol really stands for and if it necessary on windows. I am assuming the | is some pipeline notification.

Here is what I am getting back.

bzcat.exe: I/O or other error, bailing out. Possible reason follows. bzcat.exe: Invalid argument Input file = I:europe.osm.bz2, output file = (stdout)

C:Mapyosmosis-0.38bin>--read-xml enableDateParsing=no file=CONIN$ '--read-xml' is not recognized as an internal or external command, operable program or batch file.

C:Mapyosmosis-0.38bin>--bounding-box top=51.2 left=11.7 bottom=47.6 right=23.0 --write-xml file=- '--bounding-box' is not recognized as an internal or external command, operable program or batch file. | was unexpected at this time.

Please advise.

It seems like you need to write everything on one line (or something). This is an error from DOS/Windows:

 '--bounding-box' is not recognized as an internal or external command, operable program or batch file. | was unexpected at this time.

Also I think you forgot the last pipe, try to just export to OSM (or pbf) and see if that works, so write it like this:

bzcat.exe "I:\europe.osm.bz2" | osmosis.bat --read-xml enableDateParsing=no file=CONIN$  --bounding-box top=51.2 left=11.7 bottom=47.6 right=23.0 --write-xml file="I:\czechoslovakia.osm"

Why is bzcat used? I thought Osmosis could read .bz2 files anyway?

running gz/bz2 as a separate task doesn't hurt and the Java implementations have been known to be buggy (e.g. java had/have problems with gzip concatenated streams).

Instead of file=CONIN$ you have to use file"-" (see http://wiki.openstreetmap.org/wiki/Osmosis/Detailed_Usage_0.39)

In my example i used 7-zip (bzcat should work as well when using -d -c as parameters)

c:Programme7-Zip7z.exe e -so I:AdminThomasosmxmleurope.osm.bz2 | D:OSMosmosisbinosmosis.bat --rx file="-" --tf accept-ways highway=motorway,trunk,primary --used-node --write-xml file="I:AdminThomasosmxmleuropa_einfach_highway.osm"

This extracts motorway, trunk and primary street from europe

All that I can reliably tell from that error message is that bzcat.exe (not osmosis) is unhappy. So this is not directly openstreetmap related. Check the documentation if the input filename should be I:/europe.osm.bz2 rather than I:europe.osm.bz2.

Also you might have to use bzip2.exe instead of bzip, but that is unrelated as it breaks down before it ever reaches that stage.

When I supplied an incorect file name the error message was different.

I made a wrong call with the bzcat.exe. I should have called just bzcat.

(19 Jan '11, 14:09) Tomas Pajonk

I'd also recommend using europe.osm.pbf instead of .bz2, it's probably much faster to process by osmosis.

(19 Jan '11, 14:33) Breki

Would I then use Osmosis directly on the pbf or do I have to extract it somehow ?

Since this is more than a year old, I assume it is answered or not a problem. I agree however that the main problem is a Windows problem with the command syntax. For one thing, Windows commands cannot be continued.
