But\, there is so much more to it than just a point. Once relegated to government and academia\, geographic inform ation systems are becoming increasingly visible. With the PostGIS exten sion\, PostgreSQL is a first-class geodatabase and an incredible platfor m for working with spatial data\, but what is PostGIS and why would one use it? And beyond PostGIS there are a dizzying array of tools to load\ , visualize and interact with the wonderful geospatial information in yo ur database. This talk will cover GIS and PostGIS basics and provide an introduction to geodatabases and spatial queries. \;\n \;\n-- \;\n \;\nEdwin Knuth spent quite some time as a sysadmin and web deve loper before going back to school to study Environmental Science at the University of Alaska Southeast. He quickly became fascinated with Geogr aphic Information Systems and realized that GIS was just a really neat d atabase application. In Alaska\, Edwin worked on several unique project s\, including building bat detectors and using PostGIS to manage a wirel ess sensor network on the Juneau Icefield. He has lived in Portland for the past year and loves it very much. \;\n \;\nThen a trip to the Lucky Lab after.\n\nTags: postgres\, postgis\, postgresql\, pdxpug\n\nI mported from: http://calagator.org/events/1250459222 URL:http://pugs.postgresql.org/node/1649 SUMMARY:All about PostGIS (at Portland PostgreSQL Users Group) LOCATION:Free Geek: 1731 SE 10th Avenue\, Portland OR 97214 US SEQUENCE:4 END:VEVENT END:VCALENDAR
