  1. 1. Interoperable Mapping ofHealth Information during pandemic andinter-pandemic periodsEddie Oldfield – March 20th, 2012Presentation at the OGC TC, to the OGC ESSDWGAppointed Member, Resilient Communities Working GroupNational Platform for Disaster Risk Reduction (Canada)Director at www.nb.lung.caSenior Advisor www.questcanada.orgTel: 506-453-0887, Email
  2. 2. Lung Disease General Statistics 6 million Canadians with lung disease $15b annual cost to Canadians 3 million cope with Asthma (especially children) Lung cancer in women has tripled since 1977 First Nations, Inuit and Metis people disproportionately affected Poor air quality affects the health of all Canadians- leading cause of emergency room visits, hospitalization and deathMigrating populations and foreign hot-spots are not considered in the analysis of threats to respiratory health (e.g. Tuberculosis)
  3. 3. *SARS - Lessons LearnedThe National Advisory Committee on SARS and Public Health identifiedmany systemic deficiencies in responding to SARS in Canada. Amongthese were:1. absence of protocols for sharing information,2. poor coordination among health authorities at national, provincial, local levels,3. delays in identification of unknown virus,4. poor understanding of disease etiology and transmission vectors.
  4. 4. *Spatial Disease Epidemiology* Baseline Influenza vs Pandemic Indicators (influenza sub-types)* Transmissibility / Vectors / Spread electron microscope image of the Avian Flu Virus* Prevalence / Progression / Morbidity* Vulnerable Populations From Micro* Access to Health Care To Macro* Vaccine Distribution* Capacity / Demand Surge 1918* Affected Health Care Workers* Social Impacts / Critical Infrastructure
  5. 5. * Public Health Policy and Decision Making Research Provincial Policy Public awareness Prevention Health care Partnerships (Legislation, Behaviour Change, (Detection/Diagnosis Primary care, Regional Exposure Reduction, Risk Community Support, Emergency Communication) Preparedness) Health outcomes National &International Surveillance, Monitoring Determinants of Health
  6. 6. Maps Can Help Us Make the Links Heat Stress Air Quality Syndromic Surveillance Hospitalization Costs Public Health Resources Health Indicators
  7. 7. What What What How will health specifichealth data this benefit indicators end- will be decision- will be products available? making? available? will result?
  8. 8. Data Integration From Data to Maps Data LicensesData PrivacyData ModelsData TrendsData Access
  9. 9. *Mapping Methods Hierarchy in Web Feature Service* Cell distribution * Frequency, cumulative, Normative distribution methods * Four geolayers: Province, Health Region, County, Dissemination Area
  10. 10. *Mapping Methods Hierarchy in Web Feature Service*Contourdistribution *Inverse Distance Weighting method *One geolayer: Province/State; with 4 boundary overlays (Health Region, County, *Mapping Methods Metropolitan, and DAUID levels)
  11. 11. Time series automation with time-tag in WMS
  12. 12. Quick Web Map Viewer (to consume WMS, WFS, WPS) Operations Center / Remote Participants Time series automation with time-tag in WMS
  13. 13. *
  14. 14. NBLA Web Mapping Portal OGC compliant web-mapping application provides access tocredible, closest to source, health, population, and environmental indicators in support of decision-making
  15. 15. *
  16. 16. * Real Time collaboration…
  17. 17. *These Sample Maps Are Health Maps from PreviousGeospatial Projects (2003-2008)
  18. 18. *NB Lung’s Flu Clinic Locator enables a public user to search for the nearest flu clinic in their Forward Sortation Area (first three alphanumeric characters in the 6-digit postal code). *
  19. 19. *The map will refresh on the FSA location chosen, with points indicating the location of nearby clinics. *
  20. 20. *1. User Needs Identification Key innovations: 1. Health Web Mapping Architecture (Ontology,2. Cross-Border Data Assessment – Spatial and Temporal data driven); Dictionary 2. HXML (for Health data mapping, data exchange);3. Database Design: Relational, 3. PPGIS in health planning and emergency Hierarchical, Temporal (triggers / management; procedures) 4. Web & Mobile viewers (ability to invoke OWS,4. Statistical Design: Historical submit location based environmental or health data, retrieve maps and feature data), export Prevalence of Influenza; Pandemic results, etc. Simulation; other surveillance data5. WMS, WFS, WPS Design Specifications6. Client Interface Design7. Development + Implementation8. Pandemic Exercise (using distributed WMS, WFS, WPS; to produce maps for mobile, easy and advanced map viewers on the web)9. Evaluation
  21. 21. *We consumed services in the CGDI:*Web Map Services*Gazetteer / Coverage Services*Lookup services for Postal Code, Watershed, NTS Mapsheet*Spatial Reference System Dictionaries*CGDI Resource Registry Service*Event Notification Services*(Styled Layer Descriptor)
  22. 22. We Implemented OWS architecture for Health Mapping:• WMS (with time tag), WFS (hierarchical model), WPS (web process services), SLD…• Health XML (HXML) data model schema, enabling any health authority to publish into Web Map Services or National Atlas• Health Mapping relational data schema, Hierarchical schema (for Maine, New Brunswick, all of Canada), Statistical DB automation and visualization for health or environmental data• Application integration and mashup (consumed OWS, tools/features, availability through browsers, web and mobile)• Custom map viewer and features which enabled users to submit query parameters for WPS – interact with the map – find and classify data – add points of interest, and export results.• Custom map viewer for wrapping processes in dynamic interface that could be deployed on any website or desktop• Publication of maps and features in CARIS Spatial Fusion and ESRI ArcGIS Server (FLEX and .net)• Custom map viewer (Quick Map) for pandemic exercise• Collaboration Forum including web map exchange (permissions based)• Pandemic simulation (moderate style, 550,000 records, 12 weeks)• 1,600 map layers published in CGDI• Configuration and Administration modules, to publish or consume WMS/WFS, manage user/content permissions• Use authentication handled in the application (though we envisioned DRM at service level), and services provisioned behind firewall, to high-speed fiber network
  23. 23. ViewEnvironmental Health Information AddEnvironmental Health Information
  24. 24. *Introducing Your Profile* New User Registration • Edit your profile• Map Views are assigned to your Profile

  27. 27. * One of our Community Outreach Programs, Asthma Camps, is designed to assist children with chronic asthma, their guardians,healthcare providers, peers and the general public to recognize, assist and respond to the many issues surrounding this debilitating disease. *
  28. 28. * When the spatial distributionof Asthma Camp participants’ origins overlays the spatial distribution of Asthma hospitalization outcomes, our program directors, project funders, healthcare plannersand providers are readily able to determine significant historical gaps and futureopportunities for the Program. *

  34. 34. Our custom Map ViewerInterface enabled the user tocombine:1. Web Processing Services2. Web Feature Services3. Web Mapping Servicesinto a multilayer seamless viewexportable to the user’sdesktop workstation. *
  35. 35. The User defines whichcombination of values toobtain for geometry,respiratory disease,gender, age, admissionyears, statistical methods,classification methods,legend range, etc. *
  36. 36. When satisfied with thevalue settings, the Usersubmits a call to the WebProcessing Service to obtainthese values from theOracle server and,simultaneously, a call to theWeb Feature Service toobtain the spatialgeometry. *
  37. 37. Call being made by ourcustom MapInterface toour Geoserver via theWeb Feature Service(WFS) GetCapabilitiesoperation. *
  38. 38. When the Web FeatureService (WFS)GetCapabilities operationreturns the spatialgeometry, the WebProcessing Service mapsthe cell values obtainedfrom our Oracle server tothe spatial geometry. *
  39. 39. User is then able to exportthe map view to theirdesktop for further analysis,or import the view into aweb page. The exported mapview has the same GISfunctionalities as the originalMap Viewer Interface (Pan,Zoom, Layer toggle, etc). *
  40. 40. Through the Web ProcessingService, the User also hasthe ability to verify thestatistical quality of the cellvalues being mapped to thespatial geometry. *
  41. 41. Users can select Population Distribution by Health Regionparameters forstatistical queryingand map visualization
