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

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

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
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
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
