Federated data model to improve accessibility of distributed cadastral databases in land administration

Tuladhar, Arbind Man ... [et al.].

Geo-Information System manages a large volume of data concerning tenure security and market value and use. These data play dominant roles to the economical and environmental development of our society. Currently, such data are usually managed by many agencies in a distributed and heterogeneous processing environment in land administration within their organisational mandates. In such situation, the users such as individuals, notaries, real-estate brokers, surveyors, planners, municipalities and others face tremendous challenges in getting these datasets and integrating them into a single synchronous, consistent dataset using available GIS software. This paper proposes the use of a federated data model (FDM), which acts as integrating layers on the top of the existing cadastral database systems distributed at the different locations. If such FDM is implemented in a single synchronous, consistent federated database system, the users would be relieved from the complex tasks of integration and yet get a consistent dataset for their uses at lowest possible cost.
