Abstract:   (5490 Views)
Using 3D spatial data causes efficiency in urban planning and faster decision making. Within the last years, such terms like Volunteered Geographic Information (VGI) and User Generated Geographic Content (UGGC) appeared, and produce a completely new phenomenon in public collecting spatial data and define a new source of data. Adding 3D data to VGI is an important step. It seems, there is not an interoperable method for collecting and sharing 3D data in the current VGI. The purpose of this study is to provide guidelines in VGI systems for preparing 3D building models. Therefore in this study, "Wall", "Roof", "Door" and "Window" were considered as the fundamental building structural elements. Then we have developed a hierarchical classification based on ontology, for describing the interaction of these elements. A methodology for collaborative development 3D building models is suggested. Within the framework of our work, users are able to add 3D information in VGI interactively. On the other hand, is looking for ways to increase non-expert users’ participation. For this purpose, a user can upload pictures of buildings that are used for texture, then as well as digitizing aerial images, digital images are superimposed on the buildings. It causes that data entry to be adequate.
Keywords: Volunteered Geographic Information (VGI), 3D building Modeling, interoperable 3D information, 3D VGI
