    Geo-Information in Animal Disease Outbreak Management Geo-Information in Animal Disease Outbreak Management Presentation Transcript

    • Geo-Information in animal disease outbreak management Esri European User Conference, October 2011, MadridHenk Janssen, Igor Staritsky and Bas Vanmeulebrouk (Alterra, Wageningen-UR)Arco van der Spek, Paul Leijs, Dennis Kok (Food and Consumer Product SafetyAuthority, Ministry of EL&I)
    • Presentation setup The Dutch situation Dutch pilots of GIS in animal disease crisis management Future developments?
    • The Netherlands Slovenia SEPTEMBE 41.160 Km2 R 2007 320 km >16 million inhabitants 4 million cattle 180 km 12 million pigs 100 million poultry 3
    • Pig density Poultry density
    • Large Outbreaks in NL in recent years 1997: Classic Swine Fever (+/- 8 million animals) 2001: Foot and Mouth disease (200.000 animals eradicated) 2003: Avian Influenza (31,6 million birds eradicated, 30% of the population) Blue tongue (sheep) Q-fever (goats)
    • Research questions of nVWA(Food and Consumer Product Safety Authority in NL) nVWA needs to maintain quarantine areas nVWA needs timely, correct and complete farm and area information in case of contagious animal disease outbreak nVWA desires online (internet-based) GIS-applications as integrated part of their workflow Research question: can we prepare adequate datasets and software tools to meet the demands?
    • Workflow during disease crisis situations Farm -> suspicious Specialists team (Animal Health symptoms Service and VWA) -Veterinarian or other within 3 h - Clinical inspection source - Sampling - Filing Letter of suspicion - Declaration of suspicion Positive testingACCUTE INFORMATION DEMAND ACTION !- location of farms - Surveillance zone (10km)- location and number of animals - Protection zone (3 km)- geographic relations - Culling of infected holding + 1 km zone
    • Our approach Data: testing of coupling/quality of available datasets Software tools: The proof of the pudding… Process: embedding geo-information in workflow
    • Coupling of parcels and farm locationsCombination % parcels % grasslandUBN - BRS 64 79Postal code house nr 32 18LPIS – Annual Census 3 2No coupling 1 1
    • VisualizedataqualityLight green =arable crops
    • Pilot (web-)GIS-applications for use in contagious animal disease crises in NLPIKET (English: Picket but also Picket Officer ) Application for geographical determination and textual description of quarantine areas (Surveillance zone + Protection zone)GEMMA (Geographic Event Management and MonitoringApplication) Data-selection tool, based on information from Dutch LPIS (‘BRP’), I&R, GIAB (farm location (x,y on shed level) Internet based Time line
    • Protection and Observation areas Avian Influenza Observation areacompartment Bufferzone Bufferzone 10 km T-area 3 km Protection B-area area Culling area (1km) Vaccination area
    • First step: PIKET: describe quarantine area
    • Suspicion site (roads, rail, water way)
    • Suspicion site (only roads)
    • Suspicion site (roads, etc. + junctions)
    • Suspicion site (barricaded junctions)
    • Suspicion site (‘stops’ around zone)
    • Suspicion site (route around zone)
    • Suspicion site (description of route)
    • Suspicion site (with aerial photo)
    • GEMMA: Use of different map layers Active layers selectable by placing a ‘tick’, the ‘i’ makes the data of the geo- objects ‘identifiable’ Identify to show details Map layers are served using ArcIMS (ESRI)
    • Creation of a new suspicion New suspicion by selecting a agricultural holdingPan and zoom in the map (standard functionality) New suspicion by selecting a location on the map Circles with adjustable radius
    • Selection and presentation of farms Foot and Mouth- suspicion Initial suspician Different sub-selects (based on defined circles) Farm with parcels within the circles
    • Interactive drawing of boundaries Digitizing tools Time line tool Second suspicionDigitized area with a name
    • Presentation of the timeline of suspicions‘Free’ holdings in green Timeline selector ‘Free’ holding restricted by second suspicion
    • Details of a holding Inspection tool (for details of the farm) Data from I&R and Annual Census Parcels of the selected holdingHolding 221449 in Google Maps Holding 221449
    • Reports A printable map (PDF) All holdings in ExcellHolding 221449
    • Process support in crisis simulation/training
    • Support of crisis simulation/training
    • Support of crisis simulation/training
    • Concluding remarks nVWA/EL&I have the data Work flow can be supported using geo information/GIS Need for synchronizing developments Next step is operational integration of data, tools and end user process
