Project Catastrum Grenzsteine-State of the Art in Czechia

This paper summarizes information on project Catastrum Grenzsteine and its state of the art in Czechia. Project Catastrum Grenzsteine aims at submitting selected historical boundary marks and related infrastructure for the UNESCO World Heritage title. Reasons for this proposal-example of continuity of administrative units, example of technical knowledge, etc.-are given briefly while the rest of the paper presents several researches that have already been accomplished in this scope-reconstruction of boundaries of former administrative units is based on written documentation of former cadastres. Classification of boundary lines expressing probability of the presence of historical boundary marks is based on analyses of landscape and coincidence of former boundaries. Finally, the web application for crowdsourcing of historical boundary marks data is described.
