MAP: Evolution of artificialised surfaces in Alsatian municipalities between 2000 and 2011/2012, evolution of surfaces in ha (BdOCS v2)-A4

This map was made with the aim of quantifying the evolution of artificialised surfaces in each Alsatian municipality over the period 2000-2011/2012. This analysis is based on the volume of additional artificialised areas counted between 2000 and 2011/2012 in absolute value in hectare. This mapping is part of the BdOCS-CIGAL project, its realisation is based on the exploitation of the three BdOCS-CIGAL 2000, 2008 and 2011/2012 in updated version 2. The punctual figures are proportional to the importance of the phenomenon per commune ranging from -22.03 ha to + 143.50 ha of evolution. The raw values highlight the evolution of Alsatian agglomerations, the impact of the Eastern European LGV in the Bas-Rhin, the Piedmont des Vosges and the region of the three borders. It is noted that 97 % of Alsatian municipalities experiencing an increase in artificialised surface area, 1.5 % stagnating and 1.5 % showing a regression. This mapping is carried out for a print planned in A4 format, color, portrait orientation.
