Geo-ICT technology push vs. Cadastral market pull

This paper discusses the recent Geo-ICT developments, such as information system modelling standards, database technology, global positioning systems, Internet development, wireless communication and acceptance of geometry standards within general ICT tools and its uses on cadastral systems. Efficient design, development, testing and maintenance of cadastral systems allow the introduction of such systems within acceptable time and budgets. A basic condition for system development is analysis of user requirements. Those requirements can change in time, e.g. because of changes in legislation, governmental policy, new tasks for organisations or technology. It is therefore important to design generic and flexible information systems, e.g. to follow the (data) model driven architecture (MDA).
