Historic Maps promote recent Flood Risk Research – the Case of the Upper Elbe RiverSchumacher, Ulrich 10 June 2013 (has links) (PDF)
At the Leibniz Institute of Ecological and Regional Development (IOER) in Dresden scientists work to investigate landscape dynamics and their cumulative environmental effects. Historic flood maps are important sources of information when evaluating past floods and making comparison with more recent ones. There exist two maps documenting historic Elbe floods in Saxony in 1845 and 1890, and their contents have been analysed and compared with recent flood data of 2002. This paper will discuss both the specific characteristics of such unique historic maps and the problems of their incorporation into the GIS workflow, including the derivation of land use from the maps and its verification. Geodata overlay of various flood events allows statements to be made about the development of flood risk in spatially differentiated areas. This valuable geodata has been placed on the internet for access by the public, planners and researchers.
