  1. Open Source Software and IPM Decision Tools: Some history& advantages vs. proprietary closed source software, and how open source software can be used for web-based database/GIS/decision support systems Leonard Coop, Research Associate Entomology Dept. and Integrated Plant Protection Center Oregon State University

  2. Software development: what tools should I use? - Performance: features/power/learning curve, etc. - Cost - License restrictions - Interoperability/Extendability - Support

  3. Unix - the basis for open source software - The core Unix approach: non-GUI, interoperable toolkit of single purpose applications - A hypothetical example: Web user uploads a data file for GIS/plotting cat rawdata.txt | datafix.pl | GRASS | gnuplot | pbmtogif | apache Web user sees a map + plot of data

  4. Open vs non-open source options Internet/Infrastructure DNS MS DNS TCP/IP IPX/NetBEUI (archaic) HTTP/HTML none SunOne/Java J2EE MS .net Server programs Email: Sendmail MS Exchange Web: Apache MS IIS File sharing: Samba MS Network Portal system: Metadot/PHPnuke,etc $$$

  5. Open vs non-open source options Client & client/server programs OS: Linux *BSD 95/98/ME/NT/2000/XP Web/Email: Mozilla MS Outlook Office Suite: Star/Open/K MS 95/97/2000/XP Photo: GIMP Photoshop Stats: R S+ Database: mySQL Oracle, DBII Web devel: perl,php,python ASP, Coldfusion GIS: GRASS ESRI ArcInfo, ArcView

  6. The future of Apple Corp: OS X (BSD)

  7. Open source options: GIMP

  8. Searching for anything on the internet: Google (runs on 2000+ Linux boxes)

  9. Finding open source software: Freshmeat.net

  10. Open source options: GRASS

  11. Managing open source projects: SourceForge.net

  12. Open source options: R

  13. Open Source Software: What is the idea behind it? - Open source computing emerged from academia - Software development is a science - knowledge is shared openly, enabling evolutionary progress - Publishing source code (methods), brings peer review and accountability to the process

  14. 1983 Richard Stallman: started the Free Software Foundation/GNU software project

  15. Staroffice: Virtual clone of MS office; version 5.2 free for Linux/Windows

  16. How compatible/useful is openoffice? From slashdot.org (Feb. 24, 2002):

  17. Where does LINUX get its name? - From OSU (sort of): LINUX is named after its inventor Linus Torvalds, first developed in 1991 while a student in Helsinki Finland. He was named after Linus Pauling, Because he was a famous chemist, and was trained at OSU

  18. Project Support Provided by: USDA Western Region IPM Grants Program (1996-98, 1999-2002) USDA Pest Management Centers - W. Region (2002-2004) IPPC (OSU Integrated Plant Protection Center) - state level IPM Commodity grants (Oregon Vegetable Commission, Oregon Essential Oil Growers League, Oregon Cherry Commission)

  19. Weather data for pest management models: free or fee? • Weather networks: • 650+ sites in OR, WA, ID, MT, WY, AK, W. Canada • Agrimet, Hydromet (Bur. Reclamation) • METAR, COOP (national weather service) • RAWS (US Forest Service, BLM) • Grower networks (e. g. Adcon, Automata) • Key website at NWS-Missoula

  20. Online IPM Decision tools using open source software - Pest Alert Systems - Portal System - Phenology Models - Phenology Maps - GIS examples with GRASSLinks - Decision Support Systems

  21. TV Pest Alert System - OSU Malheur Exp. Station

  22. New IPPC Pest Alert System

  23. New IPPC Pest Alert System - example posting

  24. Online IPM Decision tools using open source software - Pest Alert Systems - Portal System - Phenology Models - Phenology Maps - GIS examples with GRASSLinks - Decision Support Systems

  25. IPPC/PM Centers NW Coalition Portal System - Prototype

  26. IPPC/PM Centers NW Coalition Portal System - Prototype

  27. IPPC/PM Centers Portal - full portal under development

  28. IPPC/PM Centers Portal - login required for full features

  29. IPPC/PM Centers NW Portal - "My" Portal Page

  30. IPPC/PM Centers NW Portal - Custom Channels plus email/pager/ICQ notification

  31. IPPC/PM Centers NW Portal - Customize Layout

  32. Online IPM Decision tools using open source software - Pest Alert Systems - Portal System - Phenology Models - Phenology Maps - GIS examples with GRASSLinks - Decision Support Systems

  33. IPPC Weather Data & Degree-Days Website - since 1996

  34. GRASS -free & open source: the "Linux" of GIS

  35. PRISM - Parameter-elevation Regression on Independent Slopes Model located at Oregon State University www.ocs.orst.edu/prism

  36. DD maps: downscaling algorithm from 4 to 0.5 km/cell (64-fold in 2 dimensions) Use the GIS to calculate local 5x5 weighted regression equations for each cell at the coarse resolution (4 km), model is cumulative DD = a + b(elevation) Save model parameters a & b as maplayers At the high resolution (0.5km), use model parameters to estimate cumulative DDs and use distance-weighted averages to smooth edges Display new downscaled maps

  37. Original map - 4 km resolution

  38. Gaussian smoothed map (based on 4 km resolution) Middle Mountain not apparent

  39. Downscaled map - 0.5 km resolution Middle Mountain apparent

  40. Preliminary validation of downscale algorithm:map-predicted vs actual DDs ------------------------------------------- Data sources correlation coefficient vs. actual DD orig (4km) gaussian downscaled ------------------------------------------- verification sites (included in mapmaking) (5 locations) 0.99 0.97 0.99 validation sites (excluded from mapmaking) (7 locations) 0.67 0.76 0.81 -------------------------------------------

  41. IPPC Weather Data & Degree-Days Website - since 1996

  42. IPPC Weather Data & Degree-Days Website: daily DD maps

  43. DD maps now with downscaling - Medford region

  44. DD maps - Grower run network in Medford

  45. DD Maps - deviations from normal (up this year 150 DDs)

  46. Targeted DD maps: Downy Brome in Hermiston, Lygus bug in Ontario (Treasure Valley)

  47. IPPC Weather Data & Degree-Days Website
