The many faces of Ecotrust
Why Open Source? Freedom!!!Four basic freedoms (The Free Software
Foundation):
The freedom to run the program, for any purpose.
The freedom to study how the program works, and
adapt
it to your needs. Access to the source code is a precondition for
this.
The freedom to redistribute copies so you can help
your
neighbor.
The freedom to improve the program, and release
your
improvements to the public, so that the whole
community
benefits. Access to the source code is a precondition for this.
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

Ecotrust – Future Directions
At Ecotrust we are trying to help pull it all together in an Open Source context
- Mapserver as a web-based GIS- Chameleon as a client user interface- GRASS as a server side GIS for raster data layers- PostGIS as a server side vector processing engine- OGR/GDAL to pre-process data- R-Statistics & GMT for graphing and statistics
OCEANSystem – Work in ProgressSpatial User Interaction…

R-Statistics/GMT
User Interactive DST
Integration with simulated annealing algorithms for Marine Protected Areas and site assessment.
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…

Fully Integrated Open-Source GISQGIS/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
