Tonight's g uest is Katie Urey who will speak to us about [SpiderOSM](http://www.spi derosm.org). Street conflation is a long time difficult problem and thi s is a project that looks very useful. The project gives Portland lots of attention as well. \;\n \;\nSpiderOSM is an open source pytho n package for matching segments in one path network\, e.g.\, streets and trails\, to corresponding segments in another\, based on geography and network connectivity. This allows joining together attribute data from s eparate sources. Importantly authoritative jurisdictional data can be co rrelated with the rich\, crowd-sourced\, user editable and extensible\, Open Street Maps data. Multifactor match scoring\, allows data to be joi ned only for high confidence matches. \;\n \;\nThe initial version of the matcher was coded in early 2014 specifically to combine Open Str eet Map data with Portland Oregon area jurisdictional data (RLIS) to fac ilitate pedestrian infrastructure analysis and planning. Since then the code has been refactored into a generally useful python package that ins talls\, via pip\, and works on all three major platforms: Mac OSX\, Linu x and Windows. The code is stable and mature\, with version 1.0 just aro und the corner. \;\n \;\nThe developer\, Michael Arnold\, is now f ocusing on developing applications\, and finding users and collaborators . On going projects where help would be very welcome include: \;\n 3\;\n1. The Portland Area Mismatched Name Survery (looking at name misma tches between OSM and RLIS identified by SpiderOSM.) Some folks at TriMe t and others at PDOT have begun this project\, but there is ALOT to be d one! \;\n \;\n2. A QGIS Plug-in for spiderOSM. Ryan Peterson has r ecently begun this project\, and would welcome help. \;\n \;\n3. H elp getting the word out: publicizing spiderOSM online and at appropriat e events. Alternately\, advice and encouragement in this process. :) \;\n \;\nAnother opportunity\, not yet begun: looking for someone int erested in developing an ESRI Plug-in for spiderOSM. \;\n \;\nRea d more about [SpiderOSM](http://spiderosm.org/)\n\nTags: gis\, open sour ce\, spatial\, data\, osgeo\n\nImported from: http://calagator.org/event s/1250468241 URL:http://wiki.osgeo.org/wiki/PDX-OSGEO SUMMARY:OSGeo-PDX monthly meeting - SpiderOSM (spiderosm.org) LOCATION:Portland State University Cramer Hall - 4th floor: false SEQUENCE:7 END:VEVENT END:VCALENDAR
