A Roadmap to Accomplish 3D Cadastres
Mohsen Kalantari & Abbas Rajabifard
Urbanisation is regarded as a significant global trend. This means cities around the world will be accommodating more population. The population demands accommodations as places for living and business activities. Cities have limited land and therefore high-rise structures have become major infrastructures addressing the needs arsing from urbanisation. However, highrise developments challenge the current land administration systems where methodologies for determining, recording and disseminating peoplees entitlement in land are predominantly based on 2D methods or simplified 2D representation of 3D complexities. The adoption of the 2D approaches will not stay sustainable. High-rise developments demand a paradigm shift so the complexities they posses in terms of entitlements of people in the 3rd dimension of height can be managed in 3D Cadastres. This paradigm shift requires a holistic study on the nature of the high-rise developments including both institutional and technical aspects. This paper presents a roadmap for accomplishing 3D Cadastres. For developing the roadmap, the paper uses a case study in Australia where requirements and stakeholders of high-rise developments in relation to 3D Cadastres area analysed. Technical and institutional issues are presented and a roadmap to achieve 3D Cadastre is discussed.
