Land administration underpins efficient land management and sustainable development. The land administration systems in OECD countries have evolved over long periods of time, typically over a century, usually from fairly simple systems that operated in limited areas to sophisticated systems that cover the whole jurisdiction and provide a comprehensive range of land administration services. Basic land administration services consist of spatial aspects (cadastral mapping) and legal aspects (registration of rights, responsibilities and restrictions) which, when combined, create a land information system. More sophisticated systems expand services and link land information systems to other key registers such as the civil, business, planning and fiscal registers. Geospatial or location-based information further enhances the ability to analyze and manage land related information in a environment and over time in applications. These ever more sophisticated systems rely on the establishment of a spatial data infrastructure (SDI) which are made possible through the adoption of standards for inter-operability and data exchange between public and private users for a variety of uses. However, approximately 70 percent of the world’s population does not have access to affordable systems to secure their rights.
