Trimet in Portland, Oregon, updating OSM

Posted by PJ Houser on 28 December 2010 in English (English)

Trimet has started working on OSM using the open datasets from RLIS and other agencies ( I, along with a few other interns, will be attempting to help update OSM with bike routes, more accurate roads, and trails. Trimet is switching to open source trip planning software (, and hopes to use OSM as the data source. But in this area, OSM's data isn't ready for routing. By the way, Trimet will be using its own transit layer in the trip planning software.

The Trimet team is pretty new to OSM, and we're gonna need contacts in this updating process as we don't want to mess up other people's work. I've been learning as much as I can as fast as I can from the wiki and mailing lists. I've already contacted a few users for information.

We will definitely want input before we do any bulk imports or automated editing using RLIS data, like bike routes, street centerlines, and trails. We haven't quite figured out how to do that anyways.

Anyhow, just wanted to keep everyone informed.

Hi PJ! Great to hear that Portland is using OSM data. I recommend that you sign up for the talk-us mailing list and point everyone to this post. Keep us informed about how you're coming along and if you need any help or have questions! There are lots of people in the US interested in how governments can use and contribute to OSM, and Portland seems to be partly leading the way.

Great work!

I wonder if we can convince TriMet to maintain route information as relations in the system. The MAX lines have some relations already started.
