With the enactment of the Law on the Mandatory Registration of Real Estate Transactions in 1403, the National Land Registry was tasked with designing and implementing a comprehensive location-based system within one year. Focusing on this issue, this paper, in the first phase, has extracted a list of technical requirements for launching the desired system by examining the text of the existing law and regulations. Then, in the second phase, it has examined the functioning of systems similar to this system, at the international and national levels. Finally, this article presents an optimal architecture for this system, which is capable of registering and managing ownership claims, matching geographic maps, identifying registration conflicts, and communicating with related government systems. Given the technical challenges, such as handling large volumes of spatial data, ensuring centimeter-level accuracy, and maintaining information security, this research employs a hybrid methodology. This approach includes an analysis of legal requirements, a comparative study of domestic and international systems, and the design of multilayer architecture. The results indicate that the proposed architecture, which is based on WebGIS, PostgreSQL/PostGIS, and ESB technology, can effectively meet legal requirements with high efficiency and acceptable security. Additionally, recommendations such as the gradual implementation of the project as a pilot, the development of a 3D display space, and the incorporation of microservices and blockchain technology to enhance transparency are also presented.
