Digital Terrain Model of the Second Military Survey – Part of the Military Training Area Brdy

Martina Vichrová, Václav Čada

Abstract


The Second Military Survey in the territories of the former Austro-Hungarian Monarchy was performed between 1806 and 1869. The territory of Bohemia was surveyed from1842 to 1852 and Moravia and Silesia from 1836 to 1840. After detailed study of the Lehmann´s theory of displaying the topographic landforms using hachure’s, it was detected that the hachure’s in the maps of the Second Military Survey were created by means of the modified Lehmann´s scale. The representation of landforms in maps of the Second Military Survey was accomplished by spot heights represented mostly by points of geodetic control. The aim of this contribution is to propose and describe the methodology of creating the digital terrain model (DTM) from the Second Military Survey hypsometry and to analyse its accuracy. A part of the map sheet (W_II_11) of the Second Military Survey, representing the long-standing military training area Brdy, was chosen as a model area. The resulting DTM was compared with the recent reference digital ground model – DMR ZABAGED®. The conformity of terrain relief forms and elevation accuracy of the DTM derived from the Second Military Survey hypsometry were also investigated.
