Re: [openrailwaymap] Extract kilometration from map?

Hello Wolfgang,

for the purpose of calculating average speed on streetcar routes by section, I need to extract the kilometration of the lines, including stops of course.

What I do not mean is to take a tool à la Google Earth's "path" tool and re-trace the routes myself, since the vector paths are *already* in the map.

Is there any way to do this?

in a first step you could take a planet file and filter out only the objects you need. Then you could import the filtered data into a database, e.g. with osm2pgsql. With a PostGIS database you are able to do many different geographic queries such as getting all nodes that are part of a way or calculating way lengths.
