An Interoperability Toolkit for e-Land Administration

This study explores the significance of cadastral data modeling in achieving interoperability in e-land administration systems, focusing on technical, legal, and semantic aspects. It introduces tools for data management, enterprise architecture design, access, sharing, and decision support, emphasizing the need for a paradigm shift to enhance sustainable development. Key conclusions address the existing challenges in the current cadastral data model and propose changes to improve interoperability and support land use goals in the digital era.
