In Taiwan, the government has announced an urban land tax program based on Sun Yat-sen’s “equalization of land rights” and used it for equitable redistribution of the land since 1954. Despite the development of National Geographic Information System (NGIS) in early 90’s which integrated land surveying and mapping data for servicing public sectors’ demands, the assessment and demarcation of land value sections, the most important parts of the current land appraisal operations, still depend on human experience and leave fairness and justice of the results uncertain to the public. Sponsored by the Ministry of the Interior, this study aims to design and implement a heuristic procedure to deal with the vast amount of land parcels and to demarcate land value sections by land value. Here we achieve our goal by applying the divide-and-conquer paradigm to break down the administrative district into several regions using clustering analysis, to generate a lower level of land value sections for each region using automated zoning procedure (AZP), and to generate the upper level of land value sections based on the results of the lower level regionalization. To evaluate our approach, we also compare our results with the current publicly announced land value sections in both urban and suburban areas.
