52nip 2011 service_based_geoportal_enabling_whalewatching_mapping Presentation Transcript

  • 1. “Development of a service based Geoportal enabling the Mapping of Whale Watching”Münster – June 16, 2011 Tobias Kohr
  • 2. Content1. Introduction and Motivation2. A „lightweight“ SDI for Whale Watching3. Conclusion and Perspective4. DemonstrationMünster - June 16, 2011 Ballenar, Tobias Kohr 2 of 19
  • 3. 1. Introduction and Motivation• Why Whale Watching? • Economic development • Whales’ popularity• Organization of Whale Watching in Panama • 2003: “Map of Whale Sightings” (ASVEPA/IGNTG) • Up-to-date ⇒ (interactive) geoportalMünster - June 16, 2011 Ballenar, Tobias Kohr 3 of 19
  • 4. 2. A „lightweight“ SDI for Whale Watching• Geoportals are not standalone applications, but part of an SDI ⇒ Conception of a „Whale Watching SDI“ as a SOA (oriented on the geoportal/use cases)• 3 Layers: • Geoportal Client • Web Services • Data StoresMünster - June 16, 2011 Ballenar, Tobias Kohr 4 of 19
  • 5. 2. A „lightweight“ SDI for Whale Watching• Extras: • Multilingualism – English/Spanish (Thesaurus WS) • Interaction (WFS-T, WAS, WSS, login)• Whale sightings as VGI (Data quality) • Limited user group • Whales are dynamic „features“Münster - June 16, 2011 Ballenar, Tobias Kohr 5 of 19
  • 6. 2. A „lightweight“ SDI for Whale WatchingUse CasesMünster - June 16, 2011 Ballenar, Tobias Kohr 6 of 19
  • 7. 2. A „lightweight“ SDI for Whale WatchingArchitecture - ConceptionMünster - June 16, 2011 Ballenar, Tobias Kohr 7 of 19
  • 8. 2. A „lightweight“ SDI for Whale WatchingModifications during implementation• Complications to achieve multilingualism ⇒ Workaround  2 WMS interfaces per topic  Storage of „string“- data in 2 languages ! Contradicts SOA + non-redundant data!• No protection of WFS-T via WAS/WSSMünster - June 16, 2011 Ballenar, Tobias Kohr 8 of 19
  • 9. 2. A „lightweight“ SDI for Whale WatchingArchitecture - ImplementationMünster - June 16, 2011 Ballenar, Tobias Kohr 9 of 19
  • 10. 2. A „lightweight“ SDI for Whale WatchingData Management LevelMünster - June 16, 2011 10 of 19
  • 11. 2. A „lightweight“ SDI for Whale WatchingWeb Service LevelWhale Watching + Tourist. Info WMSes • SLD for symbolization • GetFeatureInfo for data retrieval • GetLegendGraphics for whale legendWhale Watching WFS-T • Insert-Request via HTTP-POSTMünster - June 16, 2011 Ballenar, Tobias Kohr 11 of 19
  • 12. 2. A „lightweight“ SDI for Whale WatchingGeoportal Client• Prominent frameworks: MapFish and Mapbender • Advanced WebGIS capabilities • Client + server components • Missing: WFS-T integration, user login• DHTML geoportal (thin-client) • Composition via JavaScript-template • Libraries: OpenLayers and jQueryMünster - June 16, 2011 Ballenar, Tobias Kohr 12 of 19
  • 13. 2. A „lightweight“ SDI for Whale WatchingGeoportal Client• Requirements • Visualization of geo-images • Illustration of feature info and legend • Sending of whale sightings to WFS-T • Validation of data • Access control via login • Bilingual menusMünster - June 16, 2011 Ballenar, Tobias Kohr 13 of 19
  • 14. 3. Conclusion and PerspectiveConclusionConception and implementation of a geoportal incl. its underlying SDI:• SOA proves to be a fitting model• WFS-T fulfills task of data manipulation• WMS is convenient for visualization, but shows limits in multilingualismMünster - June 16, 2011 Ballenar, Tobias Kohr 14 of 19
  • 15. 3. Conclusion and PerspectivePerspective - Motivation• OBIS-SEAMAP • Archive of marine mammal habitats • Data-provider: Whale watching services• International Whaling Commission (IWC) Meeting 2012 in Panamá (July 2011, Jersey) • ASVEPA: Further development and presentation of the projectMünster - June 16, 2011 Ballenar, Tobias Kohr 15 of 19
  • 16. 3. Conclusion and PerspectivePerspective – Short term• Support • Professorship of Geoinformation Systems, TU Dresden • 52N Students Innovation Prize• Current enhancements • Login: email verification, deletion of account • Modification of data model (whale groups) • Correction of whale sightings (by users)Münster - June 16, 2011 Ballenar, Tobias Kohr 16 of 19
  • 17. 3. Conclusion and PerspectivePerspective – Long term• Further enhancements • Submission of photos • Temporal filters for visualization • Additional data (e.g. bathymetry) • Upload/download of data • …Münster - June 16, 2011 Ballenar, Tobias Kohr 17 of 19
