Depiction of Line Features on Folded Maps on Example of Old Maps of the Vltava River

Abstract. Under an ongoing research project being concerned with the Vltava river in Czech Republic, it is being dealt with various aspects of the riverine landscape, considering the significant changes that have taken place in its history and also the fact that the Vltava represents the most important and longest Czech river. This paper aims to introduce a narrow part of the ongoing research – selected old multi-sheet map works connected with the river and outline the process of utilizing similar cartographic works within greater projects processing geospatial data. These maps represent predecessors of general (‘military’) surveys of the whole Czech Lands and pose a great representative of hand-written large-scale maps created without any known geometric network and may be appropriately compared with the First Military Survey maps also lacking geometric network but bringing a great amount of topographic content.
