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.
Regards
Alex
