3D cadastres and beyond
Rajabifard, Abbas
How does the cadastre deal with an urban environment that is increasingly populated and structurally complex? The development and implementation of 3D digital cadastres is now positioned as a necessary and urgent response: it is no longer just about land; it can be expected that in the future, the majority of lots created will be associated with vertical developments. It is essential that the recording, managing and communication of information about the legal extent of property rights, restrictions and responsibilities (RRRs) for vertical developments and stratified RRRs are accurate and unambiguous. The realisation of 3D cadastres, and indeed, to realise cadastres that will be sustainable into the future, requires the consideration of how the needs of current users should be balanced against the potential needs of future users. In the data-rich environment of todayys smart cities, 3D digital cadastral information offers the land administration industry new engagement opportunities. Based on a range of professional experiences, this paper offers a perspective on 3D cadastre developments and a consideration of where the future might lie; in particular, an emphasis on the role of cadastres in the genesis of new connections between wider society, across state boundaries, and in supporting the delivery of other national visions, digital economy, foundation datasets and smart cities. The realisation of 3D cadastres, and indeed, to realise cadastres that will be sustainable into the future, requires the consideration of how the needs of current users should be balanced against the potential needs of future users. We need to accommodate the needs and opportunities of future cities and consider what must be done to ensure institutional sustainability.
