BIM to GIS and GIS to BIM

Abstract

Designing of a building and urban planning are two different professions. Apart from the professional knowledge the data, the scale, the applied software are all different. However, these two areas depend on each other. In our opinion, planning does not end at the building level, since a building pertains to a street, and a street is a part of a settlement. The process of building designing has to be a part of the larger scale process of urban planning. Architects would need information the beginning of the designing, which is actually available at the urban level: localization of the parcel, the density of built environment, local architectural regulation, etc. It would be useful to give the opportunity for automated control after completing the design. Furthermore, the work of the urban planner could be highly supported by the 3D architectural models of buildings. Our work is focused on the practical applicability of the issue in Hungary rather than researching new theoretical methods. Our pilot project showed convincing results. With further improvements the implementation can begin.
