One Reference Geo-Information Source for Europe
As an example of the ELF in action, this application area, led by the Geodetic Institute of Slovenia and Kadaster of Netherlands, developed an application for visualising geo-statistics and providing the basis of a geo-statistical reference framework, dealing specifically with the INSPIRE theme of Human Health and Safety.
Human health analysis starts with information on the geographical distribution of such areas as allergies, cancers, and respiratory diseases. For this purpose, health data from environmental, health or statistical agencies is linked to administrative and/or statistical units using the ELF platform as the authoritative reference of geo-information.
It is normally a time-consuming process to connect spatial reference data and health statistics data. The mechanism developed and stored at the ELF platform eliminates this by introducing a software based on the Table Joining Services (TJS) standard developed by the Open Geospatial Consortium (OGC). Thus more harmonised, consistent and reliable infrastructure products can be delivered.
The work builds on the CASPER application for health information which today is improving the effectiveness of human health analysis and decision-making. The introduction of geo-statistics into health data will have a positive impact on the understanding of spatial behaviour of the health sector and health related phenomena (e.g. spreading of diseases). Cross-border health analysis will be made possible using harmonized spatial and health datasets delivered through the ELF Platform. New aspects of public health management will be possible with spatio-temporal analysis and reporting about health financing and management will be more transparent and user friendly. Public awareness about health problems will rise with the use of thematic maps.
The CASPER client combines available health statistics data from Eurostat with geographical information from the ELF platform. TJS was thoroughly tested and the caching is now done at the ELF platform. The CASPER client application has been modified to use the current TJS deployment at the ELF platform. The application is able to consume data from several TJS web service layers and by using TJS and the CASPER client application, the user can easily create new maps, new data and directly perform analysis on the results.
