These example files show the different ways the extent of extracts to be
created with the osmium extract command can be specified.
The config file extracts.json contains a list of all extracts that should be
created. In this case several different parts of Germany. You can download a
Germany extract and then try
this out:
osmium extract -v -c examples-extract.json germany-latest.osm.pbf
All resulting files will be written to the /tmp/ directory because of the
directory setting in the config file. You can override this on the command
line with the -d DIR or --directory=DIR option.
