  1. The benefit of GIS-reporting in the context of Water-related Health Dr. Ina Wienand (MSc GIS)

  2. Why using GIS in the context of Water & Health? • Water-related health is a matter of spatial aspects • high interoperability with environmental conditions like precipitation, soil, aquifer, geology, temperature chemical aspects • water infrastructure • epidemiology of water-related diseases GIS is able to show the spatial distribution of water-related health data as thematic maps with different layers while using tables and data in the background

  3. . . . . . . Concept of GIS vector raster attribute data Data recording + + tables polygons Data organization Geo-database lines points Data analysis maps tables Data output +

  4. Desktop-GIS versus Web-GIS Implementing datainto a desktop GIS Desktop-GIS: ArcGIS 9 Geo-database Implementingdata into the Web-GIS Storing data in a geodatabase

  5. What are the advantages of GIS reporting? • GIS presentation, layout and classification can be easily modified and adopted towards individual data • GIS include an extensive list of functions for analyzing and visualizing spatial data • GIS can be permanently updated and maps can be produced in a very short time • GIS can be used by advanced professionals and distributed to a large audience (e.g. internet) • GIS software does not have to be expensive

  6. Web-GIS mapping on a cross-national level Getting information for theselected country

  7. Web-GIS mapping on a cross-national level

  8. Development of a Web-GIS approachon a cross-national level • Differences to other static internet maps • selecting different layers (overlay layers) • zooming in and out (dynamic map) • selecting a specific region on a map • getting information of a specific country which is stored in the background for all years • labeling layers

  9. Desktop-GIS mapping on a national level Giardiasis incidence inGermany on the districtlevel from 2001 to 2003

  10. Desktop-GIS mapping on a national level Extreme values of Giardiasis incidencein Germany Spatial statistical analysis(poisson distribution)

  11. Desktop-GIS mapping on a national level Surface water abstractionper inhabitant in theyear 2001 in Germany

  12. Desktop-GIS mapping on a national level Inhabitants per drinking water extracting plantin Germany in 2001

  13. Desktop-GIS mapping on the catchment level Prioritizinglanduse risks (according to the WSP concept)

  14. Desktop-GIS mapping on the catchment level

  15. Desktop-GIS mapping on the catchment level Vulnerablepopulationgroups andresidents

  16. Results and future prospects I • Data required by the progress monitoring system of the Protocol on Water and Health have a spatial component -> GIS is an ideal reporting tool • GIS is flexible in respect of integrating and combining other additional information into one reporting system • There are GIS standards available (OGC -> Open Geospatial Consortium) which provide a platform for interchanging data, models and results

  17. Results and future prospects II • GIS analysis shows the identification of critical areas and provides therefore political action on a local basis • GIS reporting can be fully adopted in the Water Safety Plan approach (WSP) • GIS forms the basis of an effective public communication tool • Costs can be mitigated by using Open Source software and moving from desk-top applications to Web-based GIS systems

  18. Future needs for GIS reportingon a cross-national level? • The level of data collection differs between countries (e.g. district or catchment areas) • Methods measuring, collecting and preprocessing data have to be standardized • Data descriptions have to be included into the metadata or refer to an external file of definition • As a result data can be analyzed on a cross-national level and allow conclusions which cannot be reached on local basis

  19. Scheme of Cross-national GIS reporting Cross-national Web-GIS Use standardized data and metadata National Desktop GIS Country I Country II Country III …etc.
