LOW COST WEB-APPLICATION FOR MANAGEMENT OF 3D DIGITAL BUILDING AND COMPLEX BASED ON BIM AND GIS
Keywords: 3D CityDB, BIM, Building, GIS, Web-Application
Abstract. Buildings are an important focus that needs to be modeled in three-dimensional (3D) city model. 3D models of buildings can be used to assist the construction and maintenance of cities. Currently there are many technologies that can be used to manage data and information from buildings or cities, such as Geographical Information System (GIS) and Building Information Modeling (BIM). GIS is good for managing data areas or regions, while BIM is good for managing building data and information. GIS and BIM have their respective advantages and disadvantages, so a combination of both is needed to do a good management of building and area data and information. This research will use an open source web-application that can be used for asset and facility management. This web-application can display two-dimensional (2D) GIS and BIM data, but cannot display 3D GIS data yet. The results of surveying and mapping and from existing architectural drawing can build 3D GIS data using 3D City Database (3D CityDB) which is integrated with the web-application used.The purpose of this study is to store building and city data, visualize it in a 3D model, and use it to perform spatial analysis in customized open source web-applications. The study cases for this research are campus area of Institut Teknologi Bandung (ITB), Sayang Village, and Penglipuran Village.
