That doesn't want to work for me. I have the latest germany file and
when I run that (with enableDateParsing set to no, otherwise it won't
even start reading it), I get this error:
maarten@watcheye:~/osm$ osmosis/bin/osmosis --read-xml
file=germany-latest.osm enableDateParsing=no --simplify-ways
epsilonMeters=10 --write-xml file=germany-simplifyied.osm

Ok, I found out that osmosis-simplifyways is not compatible with osmosis 0.43.1.
It will work with 0.39.
But the tool is buggy. It removes nodes from ways where it connects to other
ways. So in my example it ends up with
<way id="1">
<nd ref="1"/>
<nd ref="6"/>
</way>
<way id="2">
<nd ref="3"/>
<nd ref="10"/>
</way>
It does not delete node 3 because it is still in use by way 2, but it will
delete it from way 1, therefore totaly breaking any connectivity.
Furthermore: it does not delete nodes from the osm file. Unused nodes are left
in the file as stray nodes.

Hi,
is there a tool already existing that can simplify ways in an .osm
file?
What I'm looking for is something that removes all intermediate nodes
from a way, as long as they are not used in another way.
Example:
<way id="1">
<nd ref="1"/>
<nd ref="2"/>
<nd ref="3"/>
<nd ref="4"/>
<nd ref="5"/>
<nd ref="6"/>
</way>
<way id="2">
<nd ref="3"/>
<nd ref="7"/>
<nd ref="8"/>
<nd ref="9"/>
<nd ref="10"/>
</way>
After simplifying:
<way id="1">
<nd ref="1"/>
<nd ref="3"/>
<nd ref="6"/>
</way>
<way id="2">
<nd ref="3"/>
<nd ref="10"/>
</way>
And then also remove the unused nodes from the osm files.
