The role [of] cadastral data modelling in e-land administration

Kalantari, M. ; Rajabifard, A. ; Wallace, J. ; Williamson, I. P. (Centre of Geo-Information Technologies (cGIT), 2005)

Enablement of land administration with Information and Communication Technology (ICT) is heading toward e-Land Administration (e-LA): the transformation of land administration through the use of ICT. Existing initiatives include providing land information on line, electronic conveyancing, digital lodgement of survey plans, and online access to survey plan information. Thus far, implementation of these initiatives is isolated in their specific subsystems without reference to the broader land administration system or its core policy function of supporting sustainable development. One solution to isolation is to develop effective communication among the different land administration subsystems by harmonising data and functionalities, so they are capable of being used by all subsystems. The key to harmonisation is data modelling which both recognizes and reengineers existing business processes. Modelling allows every single process in land administration to influence the cadastral data model and vice versa. This paper describes the importance of cadastral data modelling in data management as well as coordination among subsystems in an e-LA.
