Accurate land measurement and documentation of land ownership and use are critical for effective land administration and management. However, traditional land measurement systems are often inefficient, inaccurate, and lack transparency, which can lead to disputes, fraud, and corruption. To address these issues, the authors propose a smart contract-based land measurement system that provides a secure, transparent, and efficient way to measure and document land ownership. The system utilizes smart contracts, which are self-executing code stored on a blockchain, to automate and streamline the land measurement process. The smart contracts automate the process of measuring and recording land data, ensuring that the measurements are accurate and tamper-proof. Furthermore, the system allows multiple parties, including landowners, surveyors, and government agencies, to access and verify the data in real-time, improving transparency and reducing the potential for disputes.
