Historically and cartographically, one can trace the changes in the riverbed of the Mura from the 16th century. In the past 500 years, the main stream and its branches have repeatedly and significantly changed position and course. This can be observed in great detail through cartographic comparison and layer-by-layer mapping.
There are several periods of development of techniques and cartographic representations for this particular area:
– from approx. 1500 onwards: panoramic displays on wall paintings
– 1678: publication of Vischer’s maps
– 1714: Ducatus Stiriae novissima tabula map by J. B. Homann
– 1763-1787: first military (Josephine) survey
– 1806-1869: second military survey with the implementation of the Franciscan Cadastre (1824-1860)
– 1869-1887: third military survey
– 1890-1925: the first modern special maps for the whole of the Austro-Hungarian Empire, issued after the break-up of the Danubian Empire; also published in the Kingdom of Serbs, Croats and Slovenes (SHS)
– from 1970 on: cyclical aerial photogrammetric measurements of Slovenia
– from 1972 on: availability of optical satellite imagery
