Abstract
This paper presents the lifecycle of 3D data in cultural heritage sites with a long-term and cyclical renovation
process. 3D data is obtained in different periods with different sensors – ground laser scanning, drones, photographies
of eralies period and simple measurements. In cultural and historical heritage objects, restoration works are carried
out seasonally and in the conditions of available financing. 3D data and its supplementary data have much wider applicability
beyond restoration or monitoring works. The data can be transferred to tourism, where it is used both for
virtual reality (VR) or augmented reality (AR) technologies, and for the restoration using the HBIM approach. Thus,
the data is transferred for re-use for restoration, tourism, and object management. The article discusses the acquisition,
processing and application of 3D data for the creation of HBIM with the possibility of use in VR/AR equipment. This
paper also examines the issue of updating data after restoration works, covering solutions for data publication. The aim
of this work is to diversify the use of data in the long term without re-documenting full objects.
