Official Statistics Web Cartography in Germany − Regional Statistics, Federal and European Elections, Future Activities − Joint Working Party meeting on "Geographical Information Systems for Statistics" on March 16-17, 2006 in Luxembourg

Agenda Introduction Pseudo-dynamic and static maps with election data Interactive atlases of regional statistics and election data Interactive maps for spatial examination of external trade statistics Outlook

Introduction Web cartography of regional statistics and election data in the official statistics becomes more important Technologies applyied for web cartography are highly different in the federal government and states Up to now there are no consistent maps available in the Internet with official statistical data at LAU level for the whole area of Germany So far only administrative and national election units are used for spatial reference of statistical and election data Politische Gremien: IMAGI, GIW Öffentliche Datenanbieter: GDI-DE, Länder-GDI, Verwaltungsdaten einzelner Gemeinden und Regionen

Pseudo-dynamic and static maps with election data Pseudo-dynamic maps for the election of the German Bundestag in 2002 with simple interactivity Static maps with election results of the German Bundestag in 2005 and of the European elections in 2004 for customers who can not or do not want to install map viewer software (e.g. SVG plugin)

Pseudo-dynamic maps with election data Election of the German Bundestag in 2002

Static maps with election data European elections in 2004 Election of the German Bundestag in 2005

Interactive atlases of regional statistics and election data SVG atlas of regional statistics since 2004 Maps of regional statistics at NUTS 3 level for the whole area of Germany Redemption of the former print edition SVG atlas of European elections in 2004 Maps with election results at NUTS 3 level Enhancement for static maps at NUTS 1 and 3 level SVG atlas with election results of the German Bundestag in 2005 Maps with election results at national election units level Enhancement for static maps at NUTS 1 and national election units level Politische Gremien: IMAGI, GIW Öffentliche Datenanbieter: GDI-DE, Länder-GDI, Verwaltungsdaten einzelner Gemeinden und Regionen

Interactive atlases of regional statistics and election data SVG atlas of regional statistics since 2004 Politische Gremien: IMAGI, GIW Öffentliche Datenanbieter: GDI-DE, Länder-GDI, Verwaltungsdaten einzelner Gemeinden und Regionen

SVG technology in the Federal Statistical Office Technical concept SVG client with JavaScript MySQL database with PHP support Advantages Very fast after the client application is downloaded Visually appealing Disadvantages The geometrical and statistical data are extractable Using of grid data not possible SVG plugin is necessary Politische Gremien: IMAGI, GIW Öffentliche Datenanbieter: GDI-DE, Länder-GDI, Verwaltungsdaten einzelner Gemeinden und Regionen

Interactive maps for spatial examination of external trade statistics as from midyear 2006 Technical concept Internet map server ArcIMS Middleware ArcSDE ORACLE database Active Server Pages Concept of contents Visualization of global commodity flow Maps, tables and charts Interactivity Spatial selections and queries Politische Gremien: IMAGI, GIW Öffentliche Datenanbieter: GDI-DE, Länder-GDI, Verwaltungsdaten einzelner Gemeinden und Regionen

Internet map server technology Advantages Visibility of map components can be managed scale-related Data security is completly warranted Usage of every geodata format is possible No plugin or client application is necessary Disadvantages The development of applications and interactive functions is more complex in comparison with SVG High costs at the beginning when commercial software products are used Politische Gremien: IMAGI, GIW Öffentliche Datenanbieter: GDI-DE, Länder-GDI, Verwaltungsdaten einzelner Gemeinden und Regionen

Outlook Technical maintenance and update of contents for the interactive atlases of regional statistics and elections will be continued Further development of the Internet map server technology in the Federal Statistical Office is intended e. g. for the register of municipalities (LAU 2) Initiation of grids as a spatial reference system for the cartographical visualisation and spatial examination of statistical data will be aspired
