Abstract
Nowadays in Vietnam, although still adopting the policy that land itself is not individual property, land-use rights, such as exchange, transfer, rent, inheritance or mortgage, are considered as property in reality. This means that a trading market of land-use rights is emerging and becom-ing increasingly popular. In order to manage and develop this market, it is necessary for Vietnam to have a land appraisal system based on market economy principles. On the other hand, the develop-ment of a GIS and its applications to property appraisal can help the property appraisal to be more convenient and accurate. Recently, a Vietnamese National Geographical Information System is in the first step of development and the GIS will be applied in many other fields such as the environ-ment, cadastres, etc. This paper proposes a land valuation system for Vietnam after considering other countries' property valuation systems, especially the Korean Official Announced Land Price, and applies GIS techniques for the system. Especially by network analysis, distances from the main roads are computed in the real distances travelled along the roads rather than calculated perpendi-cular distances.
