Ill bring the js library files for leaflet and the various plugins we will be using. If you have a temporal dataset\, bring it... Ill have a couple of datasets to choose from though. Our goal will be for everyon e to create at least one temporal point visualizations. An example woul d be the point locations of where floods occurred with the location\, si ze of flood and date of flood event. With this data we could create a t emporal proportional symbol map. The user will be able to click on the locations for specific locations and also use a slider to see when and where floods occurred over time.

Tonight's gu est is Dave Mangold\, who will speak to us about how to create great car tographic products using QGIS and Inkscape. \;\n \;\nAttendees of FOSS4G will remember the excellent map that Dave produced for the printe d program [1]. \;\n \;\nFrom Dave's Description of his map: \; \n \;\nThis map was created entirely from freely available data and o pen-source software. Data were obtained as shapefile downloads from METR O RLIS. These shapefiles were then loaded into a PostGIS database as spa tial tables. The initial map was created in QGIS. This map was then save d in a vector format and finished in InkScape\, where label adjustment a nd creation\, feature layering\, and annotation were accomplished. On th e map\, if you look closely at the southern portion of Naito Street (rig ht edge of left panel)\, you will see a hidden tribute to the free and o pen-source resources used. \;\n \;\n[1] https://2014.foss4g.org/wp -content/uploads/mapgallery/orig/150.png\n\nTags: gis\, open source\, sp atial\, data\n\nImported from: http://calagator.org/events/1250467585 URL:http://wiki.osgeo.org/wiki/PDX-OSGEO SUMMARY:OSGeo-PDX monthly meeting LOCATION:Portland State University Cramer Hall - room 409: 1721 Southwest Broadway\, Portland OR 97201 US SEQUENCE:1 END:VEVENT BEGIN:VEVENT CREATED;VALUE=DATE-TIME:20150213T220346Z DTEND;TZID=America/Los_Angeles;VALUE=DATE-TIME:20150218T203000 DTSTART;TZID=America/Los_Angeles;VALUE=DATE-TIME:20150218T180000 DTSTAMP;VALUE=DATE-TIME:20150213T220346Z LAST-MODIFIED;VALUE=DATE-TIME:20150213T220346Z UID:http://calagator.org/events/1250467856 DESCRIPTION:Monthly meeting of the open source GIS group PDX-OSGeo. \; \n \;\nDiscussion of all things spatial and open source. Tonight's gu est is Nick Martinelli who will speak to us about using CartoCSS and UTF Grids for collaborative mapping. \;\n \;\nFrom Nick's Description of the project: \;\n \;\nWarning\, this talk is about cartographer s designing and building web applications. Tasked with making a mapping application for internal business use\, we reached out for open source t ools that could be combined to produce a platform for collaborative mapp ing and data sharing. We used tools like Mapbox.js\, windshaft\, mapnik\ , and PostGIS to build a web based application that allows its users to create\, filter\, edit\, and share interactive maps and data with teams or individuals. The presentation will take you through the challenges of building on FOSS\, and the importance of small group collaborative mapp ing. Highlights will be our efforts to use great\, but occasionally spar sely documented FOSS code and tools\, and the sometimes challenging chor e of making them play nice together. Also\, discussion of why we feel co llaborative editing and creation of dynamic maps is an important future focus for web mapping applications. Last\, the product we ended up with\ , and continue to develop for private use opens up the conversation abou t how to best give back to the FOSS community from the private sector.\n \nTags: gis\, open source\, spatial\, data\, osgeo\n\nImported from: htt p://calagator.org/events/1250467856 URL:http://wiki.osgeo.org/wiki/PDX-OSGEO SUMMARY:OSGeo-PDX monthly meeting - CartoCSS and UTFGrids for collaborati ve mapping LOCATION:Portland State University Cramer Hall - room 409: 1721 Southwest Broadway\, Portland OR 97201 US SEQUENCE:2 END:VEVENT BEGIN:VEVENT CREATED;VALUE=DATE-TIME:20150311T192537Z DTEND;TZID=America/Los_Angeles;VALUE=DATE-TIME:20150318T203000 DTSTART;TZID=America/Los_Angeles;VALUE=DATE-TIME:20150318T180000 DTSTAMP;VALUE=DATE-TIME:20150311T192537Z LAST-MODIFIED;VALUE=DATE-TIME:20150311T192537Z UID:http://calagator.org/events/1250468044 DESCRIPTION:Monthly meeting of the open source GIS group PDX-OSGeo. \; \n \;\nDiscussion of all things spatial and open source.

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 BEGIN:VEVENT CREATED;VALUE=DATE-TIME:20150520T175731Z DTEND;TZID=America/Los_Angeles;VALUE=DATE-TIME:20150520T203000 DTSTART;TZID=America/Los_Angeles;VALUE=DATE-TIME:20150520T180000 DTSTAMP;VALUE=DATE-TIME:20150520T175731Z LAST-MODIFIED;VALUE=DATE-TIME:20150520T175731Z UID:http://calagator.org/events/1250468521 DESCRIPTION:Monthly meeting of the open source GIS group PDX-OSGeo. \; \n\n\nTags: gis\, open source\, spatial\, data\, osgeo\n\nImported from: http://calagator.org/events/1250468521 URL:http://wiki.osgeo.org/wiki/PDX-OSGEO SUMMARY:OSGeo-PDX monthly meeting LOCATION:Portland State University Cramer Hall - room 409: 1721 Southwest Broadway\, Portland OR 97201 US SEQUENCE:1 END:VEVENT BEGIN:VEVENT CREATED;VALUE=DATE-TIME:20160620T175501Z DTEND;TZID=America/Los_Angeles;VALUE=DATE-TIME:20160809T200000 DTSTART;TZID=America/Los_Angeles;VALUE=DATE-TIME:20160809T183000 DTSTAMP;VALUE=DATE-TIME:20160620T175501Z LAST-MODIFIED;VALUE=DATE-TIME:20160620T175501Z UID:http://calagator.org/events/1250470456 DESCRIPTION:Speaker: De'Mel Mojica \;\n \;\nAbstract: This talk wil l be on a general approach to automatically join large-scale\, geospatia l data across distinct data sets\, using a mix between Levenshtein Dista nce thresholds and Haversine Distance thresholds. This approach permits joining multiple data sets without the need to provide ad hoc normaliza tion conventions for each data resource. In addition\, this approach can be generalized beyond a geospatial field and applied any domain which r equires joining across two or more non-identical dimensions. \;\n \;\nWe'll visit a local watering hole afterwards. \n\nTags: api\, progra mming\, r\, rstats\, geospatial\, geo\, spatial\n\nImported from: http:/ /calagator.org/events/1250470456 URL:http://www.meetup.com/portland-r-user-group/events/230860024/ SUMMARY:pdxrlang meetup: Probabilistic Approaches to Multi-dimensional Fu zzy Joins: A GeoSpatial Example LOCATION:Mozilla: 1120 NW Couch St.\, Suite 320\, Portland Oregon 97209 U S SEQUENCE:2 END:VEVENT END:VCALENDAR
