A Digital Cadastral Data Base (DCDB) is a big investment for a jurisdiction tasked with the administration of land boundaries. In the past, the development of such a database produced no real pay-back on investment until many years, and millions of dollars had been committed. The Land Administration Domain Model (LADM) (ISO-TC211 2012) provides a model of a schema in which a progressive creation and improvement of a DCDB is possible, to allow benefits to be obtained even in the early stages of this effort. It also includes the necessary structure to ensure that a useful historical record of the cadastre can be kept. This paper explores issues to be faced in the development of software based on the LADM, which retains the history of the cadastre, and allows for progressive improvement of the data. The examples of the Netherlands Kadaster and the Queensland (Australia) Department of Natural Resources and Mines are used to evaluate the applicability of the approach.
