Initial data preparation for 3D modelling of heritage building

Latterly problems of restoration of historic buildings have become especially important. Historical buildings require special attention while preserving their cultural and artistic values, so the three-dimensional digital model of the building can be used preparing their operational or renewal plans. The aim of the presented research is to analyze strengths, weaknesses, opportunities, and threats (SWOT) of preparation the initial data, heritage building 3D model development and parametric object databases creation. The object of the research is the Sapieha Palace built in Baroque style in 1689–1691 in the capital city of Lithuania. Applied research methods and tools – initial data collection by historical drawing analysis, manual measurement, photogrammetry methods, and “As-Built” 3D model creation. The results of the presented case study were analyzed by applying SWOT methodology as well as compared with the similar studies in the scientific literature. The research provides the basis for further construction heritage studies and analysis of possible object conversion issues.
