Scope of Information in the Legends of Topographical Maps in the Nineteenth Century – Urmesstischblätter

The aim of this study is to determine the informational resource of maps (two folios) of the Urmesstischblätter with reference to the legend (three editions). Visual analysis was used as the basis for acquiring information that could be gleaned from the legends, contents of the folios, marginalia and later map. The information gathered was grouped applying the geoinformational method. The informational resource of the folios was determined by identifying separate objects present on the map with reference to the legend (number of separations in the legend), taking into consideration the geometrical type of objects. In addition, the informational resource of a folio was also defined by the number of features of these objects that can be obtained (from the legend, cartographic content, marginalia, Messtischblätter) with reference to cartographic measurement levels.
