GR-ATLAS
Interactive Atlas of the Greater Region SaarLorLux
The GR-Atlas is the central output of a research project first financed by the FNR and now by the University of Luxembourg. The area under investigation comprises the Grand-Duchy of Luxembourg, Wallonia in Belgium, Lorraine in France and the German Länder of Saarland and Rhineland-Palatinate.
Although there are numerous cross-border initiatives in a large variety of fields, it remains very difficult to gather comparable data for all regions. Currently, the atlas includes 9 maps on economic issues, 9 maps with historical content, 7 related to traffic, 7 covering environmental issues, 4 political maps, 3 on religious affairs, 2 with demographical, 2 more specifically related to cross-border commuters, 2 on tourism, 2 on cities, 1 map with linguistic data and 5 others.
Each map is composed of different layers and can be combined with other maps in order to uncover spatial congruencies. 4 maps are equipped with an interactive timeline feature. For each dot on a map a box with additional data can be consulted. Cartographical representations do not only allow to draw cross-regional comparisons but also to detect changes in intensity and trajectory over time.
