The rapid growth of population in the 21st century and the urbanization of territories have clearly revealed trends of high building and population density, transport overload, mobility, provoked pollution and urban waste problems.
These issues need to be survived by the way of data collection, knowledge base development in order to solve and manage the acute negative issues. The digitalization and creation of virtual urban reality make possible to get visual and inviseable data, develop the scenarios for urban districts, thus predict painful results of wrong urbanization. The Data set make possible to develop the strategy of smart management, city governing, public behaviour, especially in historical part of the city in order to predict the chaotic development and anti-sanitary in old districts.
These multifactorial urban research became possible through a new conceptual approach 3D Scanning, Photogrammetric survey, GIS and CAD technologies.
This video illustrates the importance of 3D laser scanning in twinning transformations in terms of Data creation, knowledge base management, prediction of time waste, loss of human and financial resources; identification and prediction of specific urban problems by the way of digital technologies, twinning approach. The article illustrates the role of 3D laser scanning in twinning transformations from virtual to real physical urban problems solving platform, support BIM technologies in the project and urban design process.
