2011 Unconference Routing Session
2011 Open Source Unconference Routing in Open Source GIS 10:00am - 11:00am, Room 333
Discussion made of routing in open source GIS. (Name?) 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 walkablity 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.
