This is a free Open Source Geospatial Unconference put on by the Portland OS-Geo User Group. Register at: http://pdxgeounconference11.eventbrite.com/
The unconference takes place the day after the GIS in Action conference and is registration is free (though we request you sign up for a ticket here to assist us in planning).
The unconference will begin with registration at 9:00am and end at 5:00pm. Coffee, tea, and water will be provided, however participants are on their own for lunch (there are numerous dining options within close proximity).
The unconference will take place in PSU's Smith Memorial Student Union building, on the third floor, in rooms 327, 328, 329, 333, and 338. Registration in room 338 (the VanPort room).
Maps of PSU Smith Memorial Student Union are available here: http://www.pdx.edu/cegs/smith-memorial-student-union.
This is a participant-driven event! If you've never been to an unconference before (Portland's WhereCamp is an excellent example), the format and sessions are determined on the day of the unconference by the people attending. No idea is too big or too small.
On Friday, we hope to have a hackathon and sprint on a problem and/or documentation. More details to be announced as this materializes.
