- 3. 3 9 maggio 2012 Mountain 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 9 maggio 2012 Actors 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 9 maggio 2012 Users 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 9 maggio 2012 Geoavalanche 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 9 maggio 2012 Goals “Exchange of snow avalanche information in a common standard for building Spatial Data Infrastructure 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 9 maggio 2012 Key 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 maggio 2012 Technologies 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 9 maggio 2012 Implications 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 9 maggio 2012 CAAML 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 9 maggio 2012 CAAML architecture Latest version 5.0 developed by CAA Autore: Francesco Bartoli 1 2
- 13. 13 9 maggio 2012 Similar 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 9 maggio 2012 EAWS 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

- 16. 16 9 maggio 2012 European avalanche danger scale 1 6
- 17. 17 9 maggio 2012 Geoavalanche 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 9 maggio 2012 Geospatial snow avalanche services
- 19. 19 9 maggio 2012 CAAML 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 9 maggio 2012 Key effects “A CAAML Spatial Data Infrastructure would exploit Geoavalanche Server which assumes a key role since it manages both of R/W operations regardless of the database schema used to store data” “When performing WFS filter queries it can also act accordingly to OGC WFS-T transactional specification because each single service has been conformed to the same CAAML schema” Autore: Francesco Bartoli
- 21. 21 9 maggio 2012 Snow avalanche SDI for cross- boarder interoperability
- 22. 22 9 maggio 2012 Benefits 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 9 maggio 2012 Challenges 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
