The Hellenic cadastre : use of modern technologies to develop an IT and data infrastructure to facilitate large scale cadastral survey procedures
Lolonis, Panos
This paper describes the major technologies and management approaches that have been adopted recently in the Hellenic Cadastre to facilitate the data collection and validation procedures. Indeed, in an effort to ensure that the selected data will have a specified quality level, reduce the risks involved in carrying-out large scale cadastral surveys and reduce the data collection and validation costs, Ktimatologio S.A., the agency responsible for the development of the Hellenic Cadastre, has adopted a wide range of state-of-the-art technologies, such as, permanent GPS stations, high-tech aerial photography and Web-based services, to achieve those goals. All these technologies are integrated appropriately to support the implementation of a series of large-scale projects that aim to develop a spatial data infrastructure for developing the Hellenic Cadastre. The paper will describe the set of those projects and will explain the philosophy that underlies them. Also, the paper will present the progress that has been made in the implementation of those projects so far and the steps that will be made in the future to complete those projects. Finally, the paper will make a critical assessment of the issues encountered in the course of the implementation and the actions that have been taken to overcome those issues. Τhe lessons learned from this process can be very useful in other settings, where either new land administration systems are developed or existing systems are upgraded.
