Development of a Desktop Application (BM_GIS) for 3D Buildings management in Geographic Information System Environment

3D modeling of cities is a graphical method to represent the real-world elements within a computer, which has become a very important and necessary for representing of contemporary cities, and doing different analyses. At present, many applications have been developed for 3D modeling of buildings around the world. However, GIS has proven to be one of the most important 3D modeling techniques of cities. The objects of 3D models represented in GIS can be associated with a set of queryable attributes, and this is not available in other 3D modeling software. In first phase, this research aims to propose a methodology for 3D modeling of buildings, and to represent each apartment as an independent unit, and to build a geodatabase by integrating ESRI ArcGIS and 3D SketchUp software. The second phase aims to develop a separate application BM_GIS (Buildings Management by GIS), depending on the Arcobjects library, for managing apartments within buildings, BM_GIS provides accurate and detailed geographic information about buildings, apartments and owners, it offers numerous tools to query databases and display results: 3d spatial and attribute data. In addition, the user can view all documents of the apartment. The methodology used in this research shows the importance of GIS in 3D modeling, representing and managing of buildings.
