Analytical Review of the Software for Creating a City Information Model

Introduction. The article describes a forward-looking technology in the field of construction industry and urban management – CIM (City Information Modeling) – an information model of a city. Emergence of the information modelling have led to the possibility to create the 3D models not only of individual objects, but also of a city as a whole with its buildings, infrastructure, geological and environmental factors. But creation and maintenance of the city models require the software tools. The aim of the present research is to make a review of the available software, describe its properties and field of application. CIM application capacities are also defined. The tasks, which can be solved by means of such a model, are described. The result of using GIS technologies in creating a city information model with respect to the data on housing stock energy efficiency level is shown.

Materials and Methods. Within the research, an analytical review of the existing software for creating an information model of a city was carried out, the works of the scientists, who contributed to the issue of urban modeling, were studied. The information sources useful for further research were identified. Geo-information systems ARC GIS 10.1 ESRI were used to create a city information model.

Results. A city information model can be described as a replication of the historical and cultural, socio-economic and religious events and phenomena; the three-dimensional models, geo-information virtual systems created by means of the space-based processing and information technologies, including BIM (Building Information Modeling) and GIS (Geographic Information Systems). The software complexes, which function based on the analysis of the valid data and creation of design entities, are used to create the information models of the urban territories. The major companies importing the urban modeling software, Autodesk and Bentley, offer both BIM and CIM tools.

Discussion and Conclusions. The term "Smart City" has become especially popular due to development of BIM technologies. This is an innovative approach based on the digital technologies application, which directly affects the activities and efficiency of provided services and rising the city living standard. For solving the thematic problems, there exist the focused technologies and tools of the modern urban environment development. The main task of the "Smart City" is enhancement of the comfort standard of the residents’ living. This task is solved by creating a city information model integrating the information about the terrain, buildings and structures, roads, green spaces, etc.
