Routing in Open Source GIS 10:00am - 11:00am, Room 333
pg_routing - postgis extension for routing
Also talked about: http://gis.stackexchange.com/
plugin for qgis
rtsql layer plugin (query builder for postgis)
Discussion made of routing in open source GIS. Ryan Dalton gave a demonstration on his attempts to us pgRouting, partly based on his readings from the blog Free and Open Source GIS Ramblings, which include the posts Drive Time Isochrones and Creating Catchment Areas with pgRouting and QGIS. It was noted that, just like in ArcGIS, one still has to build a network in order to run this kind of analysis.
There was a lot of discussion about walkability maps, walking does not take the same kind of analysis as driving or riding a bicycle would. Part of the problem is that there are no "turns," but instead street "crosses." One audience member said he was trying to overcome this problem by making four intersections.
The Willamette Pedestrian Coalition meets on Monday afternoons, 4-6pm, in Cramer Hall Lab 469 at PSU during the spring of 2011 to use GIS to model the pedestrian network in Portland. For more information, write Katie @ wpcwalks.org.
Someone brought up a question about routing on streets that have the same name and same ID but go through another city. We have a similar situation in Michigan where the city of Hamtramck is fully inside the city of Detroit. Maywood Park? - city contained within Portland - streets with the same id that get split up (similar to hamtramack)
