Urbanization is a major trend worldwide as well as in China. Geospatial information has become indispensable for the various aspects of urban development and management. The challenge for land surveyors is to provide the city managers with current, citywide, complete, and in timely manner geospatial information to support their proactive decision making. Currently cities manage considerable collections of land related information, but its separation into different component themes leads to a considerable loss in its value as a resource. Efficient and effective management of this information is of particular importance. City-wide land information management system LIMS) provides the means to integrate these themes into a truly corporate information resource. LIMS is a municipal information infrastructure, including hard and soft infrastructures. This study is mainly concentrated on soft infrastructure, which is an urgent need in China. The main objective of this research is to develop the framework, approaches and measures to enhance a city-wide LIMS in China for better servicing the sustainable development and reducing the negative impacts of rapid urbanization, and for promoting geo-economy and spatially enabled society. The research was conducted through a critical review of LIMSs overseas and in China； analysis and identification of the problems of China LIMSs； and wide reference to advanced strategy direction in the area of LIMS. This research has designed a LIMS model, developed an institutional framework, and proposed the recommendations for various legal and policy issues, including copyright protection, national security of geospatial data, funding model and pricing of geospatial data, and data management policies. A big issue in China is data sharing and coordination. Duplicated efforts are common everywhere, which not only wastes limited resources provided, but seriously damages the usefulness of geospatial databases. To better resolve the problems, the vision of a LIMS is developed, a strong governance structure is proposed, and a good partnership among all geospatial data providers and users is discussed. Technically, data sharing also needs addressing the problems in geospatial data transformation. This research also conducted an experimental study to identify and analyze the possible errors in the data conversion.
