Land Law 2013 clearly stipulates that financial management of land is one of the content of state management on land. This shows that land prices play a very important role in socio-economic activitiess and that the State may regulate prices for land management in order to ensure the interests of land users, the State, investors and social stability. The development of land price database is extremely important; however, collecting information on land price data, especially market land prices for building land price database has often taken time and effort. There is very little software to support the collection of land price information and for land pricing in accordance with the law, and such software are mainly based on desktop platforms. Therefore, with the strong development of Mobile GIS and GPS technology, this study applied software on mobile phones to collect information of market land prices for efficient and fast land price database construction.
