KNOWLEDGE SYSTEMS Open Source GIS The Ecotrust mission to utilize new innovative technology Aaron Racicot – GIS Programmer

KNOWLEDGE SYSTEMS Goals Utilize Open Source Technology –Save on cost –Rapid response to problems –Be an active participant in a community Develop web-based decision support tools –Gain a greater audience –Migrate from relying on complex/proprietary desktop software for simple GIS tasks Create a “Salmon Nation” data repository –Automated data mining –Seamless data sets –WMS/WFS/OPeNDAP server/client

KNOWLEDGE SYSTEMS Open Source Technology Fedora Core 3 Apache PHP PostgeSQL GEOS PostGIS GDAL/OGR Proj Mapserver Grass International User Groups Conferences /Web forums Source Code

KNOWLEDGE SYSTEMS Key Pieces Mapserver Web Based Mapping –Can be run as CGI or as script –Utilizes SWIG to create Mapscript environment –Interfaces to GDAL/OGR for raster and vector processing –Interfaces to PostGIS and SDE –Faster than ArcIMS PostgreSQL/PostGIS –Dynamic relational database with OGC compliant interfaces –Mainly focused on vector storage, but soon to support rasters

KNOWLEDGE SYSTEMS Web-based decision support tools Utilize powerful GIS on backend and web based GIS on front end. –GRASS – used for vector and raster based processing via command line calls from PHP. –Mapserver used to directly display results from online analysis –A new way of looking at senario based decision making Allowing users to interact –Automated file upload and run management –Web-based polygon capture for senario based simulation Ocean Planner - Demo

KNOWLEDGE SYSTEMS “Salmon Nation” data repository Ecotrust has a geographic area of interest in the area known as Salmon Nation. –Data stored in common formats (ArcINFO/GRID, PostGIS, Shapefiles, GTiff, etc) –Seamless data where posible –Automated data mining for easy data refresh –Web-based interfaces for both intranet and internet access –Seamless data extraction over arbitrary areas by chopping files or aggregating multiple files Serve our data via WMS/WFS/OPeNDAP Use remote data when possible

KNOWLEDGE SYSTEMS Cool projects underway Base data compilation –All TIGER data for USA. Compiled and processed –10 Meter DEM automated download Keyhole like zooming –Siuslaw Watershed – DemoSiuslaw Watershed – Demo User based interfaces –Utilizing PHP sessions –Custom upload/download –Saved state between sessions Applet development
