Merging statistics and geospatial information Grants 2012 13.03.2013

Expected results: Studies on the spatial distribution of statistical phenomena and the inherited causes Projects to derive new statistical data by combining existing data and geographical information. Improved data management processes whereby geoportals are connected to statistical databases Interactive map applications allowing users to delineate output areas for statistics and to illustrate the spatial dimension of statistics Projects that involve third party providers of official geoinformation such as mapping agencies are particularly welcome. Also projects using the GEOSTAT population grid dataset as a starting point are in the focus of Eurostat.

Different processing steps covered: Georeferencing data (e.g. business registers, address data) Connecting geodata and statistical data Locally Internet (OGC TJS) (standardized web service interface for automatic joining of attribute data (e.g. statistical data) to geometry (administrative boundaries, postcodes, statistical units) through distributed access) Dissemination (linked data): from products to data Visualisation techniques (e.g. commuting, health data, cross boarder) Grid approach & Data analysis (Indicators: density, spatial planning, health data)
