  1. 1. 19.05.2012 / GI2012A Snow AvalancheSpatial DataInfrastucture meetsInspire – Annex III GEOAVALANCHE1 Autore: Francesco Bartoli
  2. 2. 2 19.05.2012 / GI2012Agenda Snow avalanche risk management Natural Risk Zones theme What is Geoavalanche? CAAML application profile Geoavalanche server Benefits Challenges Autore: Francesco Bartoli
  3. 3. 3 19.05.2012 / GI2012Mountain 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 19.05.2012 / GI2012Actors 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 19.05.2012 / GI2012Users 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 professionals  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 19.05.2012 / GI2012Inspire – Annex III “Natural Risk Zones” theme  Definition: “Vulnerable areas subjected to natural hazards that because of their location, severity and frequency may potentially affect society seriously”  The knowledge of identification and delineation over risk zones is significantly important to mitigating circumstances Autore: Francesco Bartoli
  7. 7. 7 19.05.2012 / GI2012Natural Risk Zone Where natural hazard areas intersect with highly populated areas and/or areas of either particular environmental or cultural or economic value risk = (hazard) x (probability of its occurrence) x (vulnerability of the exposed populations or the environmental, cultural and economic assets in that zone) Data and special warning services are probably relevant for both risk assessment and emergency management Autore: Francesco Bartoli
  8. 8. 8 19.05.2012 / GI2012Avalanches – Snow slides Such areas prone to have:  Significantly snow cover combined with steep slopes  Windy activity that affects the creation of snowdrifts Coverage  Physical mapping of areas susceptible to weak cohesion of snow profile and easily sliding indeed  Areas divided into zones with susceptibility classification  Areas with either certain regulations or restrictions for different land use due to such risk Autore: Francesco Bartoli
  9. 9. 9 19.05.2012 / GI2012Snow Water Equivalent Areas prone to have:  Significantly few snowfalls with low impact on water generation Coverage  Physical mapping of areas susceptible to a low power of snow coverage  Areas divided into zones with susceptibility classification  Areas with resource management connected to snow water equivalent risk Autore: Francesco Bartoli
  10. 10. 10 19.05.2012 / GI2012Geoavalanche 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
  11. 11. 11 19.05.2012 / GI2012Goals “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
  12. 12. 12 19.05.2012 / GI2012Key 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
  13. 13. 13 19.05.2012 / GI2012Technologies 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
  14. 14. 14 19.05.2012 / GI2012Implications Accessing datasets by using WFS services for exchanging data on R/W operations Providing maps avalanche bulletins and snow coverages by using WMS services Enabling 3th-party internet sites and mobile devices for snow avalanche geolocalisation services Autore: Francesco Bartoli
  15. 15. 15 19.05.2012 / GI2012CAAML 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 snow avalanche types:  incident information  activity comments  observations  bulletins  closure  observations on the field  snowpack structure comments  snow profile observations  weather observations Autore: Francesco Bartoli
  16. 16. 16 19.05.2012 / GI2012CAAML architecture Latest version 5.0 developed by CAA Autore: Francesco Bartoli 1 6
  17. 17. 17 19.05.2012 / GI2012EAWS CAAML profile EAWS European Avalanche Warning Service maintains standards across the Alps Proposed schema profile for the Alps 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 Geoavalanche uses EAWS CAAML-scoped snow avalanche bulletins Autore: Francesco Bartoli

  20. 20. 20 19.05.2012 / GI2012Fit together Dataand services in Inspire might be filled by this simple rules:  EAWS danger scale CAAML-modeled turns into susceptibility classification of risk zones  Closures in CAAML would be relative to land use regulations and restrictions  All observations data types would refer to snow water equivalent and resource management indeed (Hydropower, Irrigation, drinkable, etc) Autore: Francesco Bartoli
  21. 21. 21 19.05.2012 / GI2012Geoavalanche 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 bulletins and snow water equivalent maps is Inspire-ready because of the abilities passed-down by Geoserver Autore: Francesco Bartoli

  24. 24. 24 19.05.2012 / GI2012Key effects“A CAAML Spatial Data Infrastructure wouldexploit Geoavalanche Server which assumes akey role since it manages both of R/W operationsregardless of the database schema used to storedata”“When performing WFS filter queries it can alsoact accordingly to OGC WFS-T transactionalspecification because each single service hasbeen conformed to the same CAAML schema” Autore: Francesco Bartoli
