Geoavalanche

  1. 1. GeobeyondA maggio 20129 Spatial DataInfrastucture forAvalancheAwarenessWarning GEOAVALANCHE1 Autore: Francesco Bartoli
  2. 2. 2 9 maggio 2012Agenda Snow avalanche risk management What is Geoavalanche? CAAML application profile Geoavalanche server Benefits Challenges Autore: Francesco Bartoli
  3. 3. 3 9 maggio 2012Mountain Risk Management AVALANCHES dramatically:  kill backcountry practitioners  damage villages, settlements, infrastructures SNOWCOVER frequently:  affects hydropower generation  is a source of water for drinkable and irrigation use Autore: Francesco Bartoli
  4. 4. 4 9 maggio 2012Actors AVALANCHE WARNING SERVICES  distributed offices collect avalanche and meteorological data often locally  issue nationwide nowcasting and forecasting bulletin centrally Governments  have to mitigate natural hazard and regulate land use  deal with the management of resources  are approaching to Inspire where Avalanches are issued in the Natural Risk Zones theme of Annex III Autore: Francesco Bartoli
  5. 5. 5 9 maggio 2012Users Tourists  attempt in the wilderness with a number as much as increased in the latest years  claim innovative early warning alert systems and more avalanche awareness for safer activities Mountain professionists  plan their activities more often via mobile devices  promote and make their business on the safety of outdoor activities  are actively involved to report snowdrift risk and snowslide-prone areas as the situation evolves Autore: Francesco Bartoli
  6. 6. 6 9 maggio 2012Geoavalanche Open Source project born from Geobeyond and released under the GNU GPL v3 terms Development of a web architecture to deal with snow avalanche datasets over the Internet Overcome the lack of shared knowledge on snow avalanche information Core component of data infrastructure spatially and semantically focused Web 2.0 oriented Autore: Francesco Bartoli
  7. 7. 7 9 maggio 2012Goals“Exchange of snow avalanche information in a common standard for building Spatial DataInfrastructure to cross-border interoperability” “Leverage of more avalanche awareness to mountaineers by using user-oriented services on Web channels”“Make avalanche bulletin mostly available and hence mountain experience safe-effective” Autore: Francesco Bartoli
  8. 8. 8 9 maggio 2012Key Concepts Geographical nature of snow avalanche data (spatial component) Geospatial standards Cross-boarder cooperation and harmonisation of data (Regional – National – European) Interoperability in mind Autore: Francesco Bartoli
  9. 9. 9 9 maggio 2012Technologies Canadian Avalanche Association Markup Language CAAML Geographic Markup Language GML OGC Web Feature Service WFS OGC Web Map Service WMS GeoServer and the GML application schema extension PostGIS spatial database Autore: Francesco Bartoli
  10. 10. 10 9 maggio 2012Implications Accessing datasets by using WFS services for exchanging data on R/W operations Providing maps avalanche bulletins and snow cover by using WMS services Enabling 3th-party internet sites and mobile devices for snow avalanche geolocalisation services Autore: Francesco Bartoli
  11. 11. 11 9 maggio 2012CAAML XML grammar language initially developed and still maintained by the Canadian Avalanche Association CAA Common encoding structure based on top of GML Currently supports the following avalanche types:  incident information  activity comments  observations  bulletins  closure  observations on the field  snowpack structure comments  snow profile observations  weather observations Autore: Francesco Bartoli
  12. 12. 12 9 maggio 2012CAAML architecture Latest version 5.0 developed by CAA Autore: Francesco Bartoli 1 2
  13. 13. 13 9 maggio 2012Similar features Object-Property-Value model pattern of GML Same flexibility in mind Borrows the concept of profile which permits:  express logical limitation of elements relevant for a specific application  maintain the ability to be validated against the overall CAAML standard  design a common schema which raises the needs among AWS in the neighborhood of European mountains Autore: Francesco Bartoli
  14. 14. 14 9 maggio 2012EAWS CAAML profile EAWS European Avalanche Warning Service maintains standards across the Alps Proposed schema profile for the Alps Geoavalanche uses EAWS CAAML-scoped avalanche bulletins Autore: Francesco Bartoli
  15. 15. 15 9 maggio 2012Bulletin element type Courtesy of CAA Autore: Francesco Bartoli 1 5
  16. 16. 16 9 maggio 2012European avalanche danger scale 1 6
  17. 17. 17 9 maggio 2012Geoavalanche Server Uses GeoServer to aggregate different datastores centrally Includes GML application schema extension for supporting 3th-party like CAAML Allows direct querying of complex snow avalanche features CAAML-encoded Enables data fusion between remote and local sources Achieves web mapping services for avalanche bulletin is Inspire-ready because of the abilities passed-down by Geoserver Autore: Francesco Bartoli
  18. 18. 18 9 maggio 2012Geospatial snow avalanche services
  19. 19. 19 9 maggio 2012CAAML schema mapping Single caaml:Bulletin:  is observed at several distinct locations on the Earth’s surface  has a multivalued caaml:bulletinResultsOf property of caaml:BulletinMeasurements type Autore: Francesco Bartoli
  20. 20. 20 9 maggio 2012Key effects“A CAAML Spatial Data Infrastructure wouldexploit Geoavalanche Server which assumesa key role since it manages both of R/Woperations regardless of the databaseschema used to store data”“When performing WFS filter queries it canalso act accordingly to OGC WFS-Ttransactional specification because eachsingle service has been conformed to thesame CAAML schema” Autore: Francesco Bartoli
  21. 21. 21 9 maggio 2012Snow avalanche SDI for cross-boarder interoperability
  22. 22. 22 9 maggio 2012Benefits Interoperability at largest scale for stakeholders, actors, and users EUROPEAN – Snow avalanche Geoportal for EU, which would represent the application of Natural Risk Zones NATIONAL – Geospatial product which provides avalanche bulletin maps, warning LBS to mobile users and a complement for Resource Management (Snow water equivalent) REGIONAL – A bridge to connect distributed observation centers to national agencies AWS in an easily common format Autore: Francesco Bartoli
  23. 23. 23 9 maggio 2012Challenges Schema transformation for CAAML datasets to comply with the "Natural Risk Zones" data theme Robustness and scalability of snow avalanche database for CAAML Catalogue Service for the Web (CSW) Implementation of map visualization services INSPIRE conformed (WMS 1.3) Develop of mobile LBS client (iOS, Android) Autore: Francesco Bartoli
  24. 24. 24 9 maggio 2012More on Geoavalanche Source code on github Read more on the project site geoavalanche.org Follow me @francbartoli on Twitter Autore: Francesco Bartoli
