What are Essential requirements in Planning for Future Cities using Open Data Infrastructures and 3D Data Models?

Abstract

Major urban renewal programs including higher density and infill devel-opments are being planned in brownfield and greyfield areas of the cities. These have increased the challenges in urban planning and management tasks. To address the challenges multi-dimensional and multi-spatial data is required to support city planners and policy-makers. There have been substantial improvements in developing and sharing the spatial data infra-structure. Moreover, the extended semantic capacity in 3D data models en-ables innovations in multi-dimensional urban planning and design. How-ever, using these technologies to identify semantic relationships between objects, in diverse spaces and dimensions, enabl..
