fig congress 2018 - Digital Integration of Land Records through the LADM and STDM
Glendon Newsome, Charisse Griffith-Charles
Cadastral information in many cadastral systems is comprised of various datasets held in different locations. This results in duplication of effort, and inaccessibility to comprehensive and complete land records. Integrating the varied datasets is affected by their differing precisions and resolutions, different tenure regimes - formal, informal, customary, and communal; differing formats - analogue and digital; differing supportive legislative framework - titles and deeds and systematic and sporadic adjudication; differing boundary systems - fixed and general; and differing institutional structures - fiscal and legal foundations, and centralised and decentralised operational framework. All this lack of cohesion results in ineffective land management, which stymies economic development, and leads to high cost and inaccuracy in land registration – duplication in registration of land; inappropriate development approval; weak land administration and management; and poor disaster risk reduction and management. Developing countries such as those in the Caribbean are particularly affected and made more vulnerable to economic, social and environmental shock in the presence of such inadequate cadastral systems. This paper describes a strategy for the development of an integrated digital land records management system, through the adoption, modification and application of the International Standards Organization certified ISO 19152: Geographic Information – Land Administration Domain Model (LADM) and the Social Tenure Domain Model (STDM). The paper demonstrates how the LADM and the STDM may be incorporated using generic Free Libre Open Source Software (FLOSS) technology, to support the solution to the problem of inefficient land records management in developing countries. The result is presented in the form of a new conceptual data model and tested using a prototype created with open source software. It establishes links and relationships between data created by various departments and agencies of the state, which currently, proves cumbersome to access, due to the physical distribution of the data and the multiple formats and models of its structure. The outcome is a strategic fit-for-purpose implementation of a hybrid of the LADM and STDM named LSTDM.
