LADM Based 3D Temporal Approach for Coastal Cadastre

Abstract. Effective coastal cadastre management requires an advanced framework capable of addressing spatial and temporal complexities arising from the evolving nature of coastal environments. This paper presents an LADM-based 3D Temporal approach for coastal cadastre to enhance the management of coastal property rights, jurisdictional boundaries, and land-sea interactions. The proposed framework integrates three-dimensional spatial data with temporal attributes, enabling precise representation and tracking of changes in coastal parcels, maritime zones, and shoreline boundaries. The LADM-based model is structured within a spatial database for practical implementation, ensuring seamless interoperability with GIS-based visualization and web-based monitoring tools. This approach strengthens cadastral decision-making by addressing key challenges such as shifting shorelines, overlapping land-sea rights, and the evolving legal status of marine parcels. From a legal and policy standpoint, this framework supports harmonizing land and marine tenure systems, promoting regulatory compliance, dispute resolution, and jurisdictional coordination among stakeholders. Implementation of an LADM-based 3D Temporal cadastre within a structured database framework enhances transparency, facilitates adaptive marine governance, and ensures legal clarity in coastal property administration. The findings underscore the critical need for a legally robust cadastral model to support sustainable coastal management and equitable access to marine resources.
