The challenges of reconstructing the historic urban landscape of Lublin in the Lublin Union period (1569) in an interactive map

Lublin in the Union of Lublin Period (1569) is a 2019 interdisciplinary research project with the idea to develop an internet portal (https://teatrnn.pl/unia-lubelska/), which would introduce the user to the world of 16th-century Lublin. A key task was to create an interactive map (WEB-GIS) using spatial data and noninvasive research. The basis for the retrogression of 450 years of transformation was mainly noncartographic sources of information (written sources, conservation documentation, engravings). The involvement of an interdisciplinary team and modern tools resulted in a model that, on the one hand, is state-of-the-art and, on the other, brings scientific findings closer to a non-specialist audience in an illustrative form.
