A Study on the Phased Approach to Introduce a 3D Cadastral System by Components in South Korea

Key Points

• This research examines the feasibility of implementing a 3D cadastral system in South Korea and proposes a phased introduction strategy.
• Analyzed previous studies to identify components of a 3D cadastral system.
• Defined six essential components: legal basis, registration target, survey methods, outcome determination, public announcement system, and rights relationships.
• Applied international case studies from Norway, New Zealand, Sweden, Austria, and Quebec to categorize implementation levels.
• Compared and analyzed the current state of South Korea's cadastral system using the identified phases.
• Identified three phases for implementation: Phase 1 maintains the existing 2D system, Phase 2 transitions to a mixed 2D/1D system, and Phase 3 fully realizes a 3D cadastre.
• The phased approach aims to address increased land disputes due to complex land use.
• The 3D cadastral system is expected to improve land use efficiency and respond effectively to modern demands.
