 Abstract

Interpreting planning regulations could be a challenging task for land surveyors when defining new ownership boundaries and for responsible authorities (e.g., city council) when assessing proposed developments. They need to be aware of the impacts of planning regulations on land parcels and vice versa since these regulations contain legally binding rules for all parties including government and citizens. There is a strong link between planning and cadastral regulations. For example, 3D zoning, with the capability of representing planning regulations in 3D, has a great potential to enable representing restricted and usable spaces for 3D cadastral purposes in a more visual way. This paper aims to offer a discussion about the advantages of enriching 3D zoning with the spatial representation of planning regulations in order to be integrated into a larger land-use information system called multipurpose cadastre to find better compliance between land use, urban planning, and citizen welfare. To this purpose, three groups of planning regulations (i.e., proposed design needed, 3D city model needed, and 3D zoning groups) are proposed in which 3D zoning group seems to be the most valuable one to achieve the overall objective. To support our discussion regarding mapping planning regulations for cadastral purposes, the paper results in a showcase for five planning regulations in the 3D zoning group including height limits, noise impacts, side and rear setbacks, street setbacks (side and front), and flooding limits. Victoria, Australia, was selected as a case study to illustrate some aspects of the discussion.
