Cartographic sources in the immersive geovisualization of a medieval stronghold

This study aims to combine various sources to reconstruct and create a virtual immersive geovisualization of the typical Slavic stronghold from the 10th century to its contemporary state with the utilization of cartographic heritage sources including archive maps, old sketches and paintings.This necessitates meticulous examination, compilation, validation, transformation, and appropriate utilization of cartographical heritage sources to base the virtual reconstruction of an object on the best available data reflecting its appearance at the chosen time of analysis.The lack of well-established workflows in the field of cultural heritage reconstruction introduces a significant amount of subjectivity, negatively impacting the development of a coherent reconstruction methodology for both architectural objects and terrain.The object itself has undergone significant degradation over the years of disuse, as well as changes in terrain that hinder the recognition of its topography and function.The cartographic sources as a whole -archaeological research, historical studies, and modern cartometric data come to the rescue, enabling the representation of the object in various changing states after being compiled, transformed, and compared.Based on their characteristics and respective utility, these sources will be classified as either cartometric or non-cartometric in the ways similar to the concepts of the previous studies (Zawadzki 2023).The work also tries to address the issue of double heritage when reconstructing objects: which involves the need to use cartographic heritage such as the previously mentioned old maps and drawings to reconstruct field objects considered as objects of cultural heritage
