still having e-mail problems

[Scott Parker]

We have an opportunity to work with a student from the Portland Community College (PCC) GIS program.  The student would get credit for working as an intern at Oregon Walks.  I think all we need to do is ensure they do 120 hours of creative work on a real-world GIS project.  PCC will probably want a brief evaluation at the end.  I've written up brief descriptions of three on-going projects where we could definitely use some help.  Please review the attached.  If necessary we can discuss it at tonight's jam session.  I'll send it off to PCC this evening if there are no changes.

 

I've been teaching a short community education class called "Cartography for Wilderness Exploration" at PCC for a couple years so I have some familiarity with their GIS program.  I don't have much to compare to but it seems stronger than typical Community College GIS.  They have some really good, hard working students there.  It would be very good to get some more jammers and it would be good for PSU and prospective students to meet through The Jam.

There you go again, claiming OSM is more accurate than street centerline data.  One of these days that generic statement is going to come back and bite you.  :-)

Indeed, I have found errors in both.  The biggest problem with OSM is with data that requires measurement or interpretation of a standard.  For this you need field workers to be trained and organized so that data is consistent and coverage is, at least, known if not complete.

 

There are a half dozen ways people have entered walkway data into OSM.  The end result is that we need to manually examine everything that isn't a street.

 

And what is a "Living Street" anyway?

I stand by my statement that we can make something that is better than either OSM alone or centerline alone.

OSM doesn't have it either.  It looks like they just copy the street centerline.  Except it looks like they fix the bridges.

What do you mean by "fix the bridges"?

The street centerline has false intersections where bridges cross.

[Cone, Paul]

Our data model needs to have intersections whereever segments cross in the GIS, even if they do not physically intersection on the ground.  It is a requirement of the geometric network.

Good to know it is intentional, but I don't understand why that requirement exists. Would love to learn more!

We'll see what Paul says but I think "known" is a better word than "intentional".  It goes way back to the early days of GIS.  One of the problems with being out ahead.

 

We hope that one day we'll look back at the first complete and accurate walkway network and wonder why we did it that way when there are so much better ways now.

It will help me prep for SOTM if we have a one sentence objective for our data model and a high level list of requirements.

WIll I find such in the Walk21 paper?

I'm not sure.  I have been trying to wrap my head around it.
