    • Extending Health Web Mappingusing Spatial Analytical Tools ORI GUDES (GRIFFITH UNIVERSITY) ISHARA KOTIAH (SPATIAL VISION)
    • Research problem and background 2There is growing evidence that new approaches and frameworks tohealth planning are required, that should be based on: Local information; Collaborative planning; and Evidence-based decision-making.(Murray, 2006; Scotch & Parmanto, 2006; Ashton, 2009; Kazada et al., 2009)This is important because health planning to date has not beensupported by sound evidence.For example, the cost of chronic disease to society remainssignificant, however current health planning methods have not madea substantial impact in addressing this issue.
    • Research problem and background 3According to the ABS In the last 5years there was growing evidencethat the Logan Beaudesert areaattained the highest rate in riskfactors of chronic diseases inAustraliaFrom a population of 270,000 1 in 4 people smoke 13% consume alcohol at a levelconsidered as high risk 60% are overweight
    • Research problem and background 4One of the responses by the Logan-Beaudesert community has been the Earlyestablishment of The Logan Beaudesert YearsHealth Coalition (LBHC) Optimal Multicultural Health The LBHC is a collaborative arrangement between government and non-government LBHC agencies, the private sector and community to Board develop and deliver health programs and services to the community Health GP Promotion Integration Information Management

    • Feature / Function PurposeUser Login Screen for user to log into systemMap Navigation Basic Map Navigation, including zooming and panning Features and functionalityBase Map/ Imagery View Ability to select aerial imagery or street maps as a base view workshop 10Layers Ability to view health and demographic layers of the LBHCLayer list Ability to turn layers on or offIdentify attributes Ability to view details of attributes found at a certain locationOnline Help Accessibility to text on help notes for using the systemPrint Map Ability to print a mapMap Legend Ability to view an image indicating symbology used in the mapLayer Metadata Ability to view metadata (i.e., data on data) for each of the layers used in the systemSpatial Bookmarks Ability to store the extent of a view for quick PAR zoom in Cycle 2Simple Search Ability to undertake a simple geographical search of a name field on two spatial layers: SLAs (Statistical Local Areas) and community health centresRedlining and Measurements Ability to draw points, lines, polygons and text on the mapUser Feedback Ability for users to submit feedback regarding data set issues, updates or any other requirements of the system.Accessibility analysis Ability to compute the service area of two layers (public hospitals and GPs) based on driving or pedestrian travel timeProximity function Ability to find features in specified layers (public hospitals and GPs) within a specified buffer distance of a point entered by the user
    • Workflow Accessibility Function NameDescription The literature emphasises that accessibility to health facilities has been identified as a key determinant of health.Objective To test the effect of travel time to health facilitiesEnd Users LBHC members, Logan and Scenic Rim planners Workflows and healthOutcome To Identify gaps in the provision of health facilities in the communityWorkflow 1. User logs into HDSS Prototype. 11 scenarios sample 2. A map view is presented showing SLA boundary suburb names. 3. The user zooms in to a specific area. 4. The user selects a button on the interface to calculate service area catchments for a facility layer. 5. A form appears in which the user has the option to: 6. Pick a facility layer which may be one of three types: • Public Hospitals (default) • GP Clinics • Chronic Disease Centres 7. Pick a transport mode: • Pedestrian • Private Car (default) 8. Enter in travel time, (5,10, or 20 minutes) 9. Click on a button to show the service area. The system processes the request and updates the map to show travel time from the selected facility in the map view as polygons. 10. The user can visualise gaps between polygons which highlight areas not serviced. 11. The user sends the map to the printer.Optional The user turns on a layer of population statistics to compare demographicWorkflow data to the accessibility to facilities.GIS layers • Street map/aerial imagery • SLA • Suburbs • Public hospitals • GP Clinics • Chronic diseases centres • Population statistics (optional)
