[OSM-dev] Tool to simplify ways

[Maarten Deen]

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.

Regards,
Maarten
