Hello,
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?
TIA,
Sincerely,
Wolfgang
Hello Wolfgang,

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.

Thanks for that. In that case I'll stick with the "path" tool in Google Earth though.
I had just hoped that someone would have actually thought of implementing a user interface for extracting information from Openrailwaymap. But, well, "web application" and "user interface", those two things just don't seem to fit.

the website is still in an early development stage, so there are a lot of features that are planned, but not realized so far.
But as well as OpenStreetMap, the main focus of the project is to collect free data, not to develop every possible application for free. And as well as the osm.org website, openrailwaymap.org is just a kind of showcase to present possible usecases of the collected data to attract other developers.
We spending our freetime for this project and get not enough donations to pay the server rents without using our own money. And we have not enough time to implement all user wishes. If someone wants a special feature, he could either develop an own application, or he contributes to the project by coding or donations.
Sorry for these words, but it is not really motivating when users just send feature wishes, but do not support us to realize them...
