4. Ecotrust - Salmon Nation

5. Conservation Economy

6. The many faces of Ecotrust

7. Freedom

8. Benefits/Limitations of Open Source Benefits: –Software cost = $0 –Source code is available and modifiable –User and development communities flourish –Development cycles are VERY fast Limitations: –Total cost is NOT = $0 –Many applications are not as polished as the proprietary counterparts –Compatibility with proprietary software can be an issue

9. Work Flow – Real-Time Web DST Web User Request Web User Response Static Data Storage Web Services Data Gathering Data Formatting Data Processing Map Formatting Map Production Real-Time Web Decision Support Tools

10. Work Flow – What OSGIS is good at Web User Request Web User Response Static Data Storage Web Services Data Gathering Data Formatting Data Processing Map Formatting Map Production The Problem Is The Arrows! Connecting a web request to server side GIS analysis is tricky Real-Time Web Decision Support Tools

11. Example – Real-Time Web DST Siuslaw Watershed Restoration Initiative

12. Work Flow – Real-Time Web DST Data Gathering Data Formatting Data Processing GRASS Mapserver Mapserver on the front end… GRASS on the back end…

13. Ecotrust Example At Ecotrust we are trying to help pull it all together in an Open Source context - QGIS and GRASS as a desktop supplement - PostGIS to store vector data layers - Mapserver as a web-based front end - Chameleon as a client user interface - GRASS as a server side GIS for DST development - OGR/GDAL to pre-process all of the vector and raster data - R-Statistics & GMT for graphing and statistical work

14. Ecotrust Example - OCEANSystem Chameleon Mapserver R-Statistics User driven… Web interactive tools… GIS analytical computing… PostGISGRASS

15. Where is it all going? Real-Time Decision Support Tools Integration of OS software across organizations “Google” type interfaces (smooth user experience) –AJAX driven –Streaming media –Seamless datasets Large datasets require more pre-processing Pressure on large private companies to become more responsive to end user needs Integration of OSGIS with proprietary software – required for migration path… Start of services based business…

16. The Future of GIS in Salmon Nation QGIS/GRASS GIS Web-Based Mapserver R-Statistics GMT Fully Integrated Open-Source GIS QGIS/GRASS GIS – Fully functional server GIS doing the heavy lifting. Runs on the server located at Ecotrust. UMN Mapserver – Making data accessible via the web. Geo- spatial server viewed through a web browser. Taking our vision to a growing audience. Adding the analytical glue to make smart decisions based upon sound GIS analysis. Making GIS analysis accessible and affordable for Salmon Nation
