|Abstract: ||Urbanization is a major trend taking place worldwide as well as in China. There are severe social, economical and ecological impacts in association with this rapid urbanization process. Geospatial information has become indispensable for the various aspects of urban development, planning, and management. The challenge for land surveyors is to provide the city managers at all levels with current, citywide, complete, and in timely manner geospatial information to support more proactive decision making which encourages more effective sustainable development. Currently cities manage considerable collections of land related information. But the traditional separation of this information into different component themes leads to a considerable loss in the value of the information 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 technically and institutionally integrate these component themes of land information into a truly corporate information resource. LIMS is a municipal information infrastructure, including hard infrastructure (hardware, software, and data communication and networking) and soft infrastructure. This study is mainly concentrated on soft infrastructure, i.e., institutional issues and policies, which is more important than hard infrastructure and an urgent need in China environment. The main objective of this research study 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 by comparing with the good practices worldwide; discussion with several city LIM managers of their existing systems, problems and potential improvements and solutions; and wide reference to advanced strategy direction in the area of LIMS. This research study has designed a LIMS model, developed an institutional framework for a LIMS, 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 for developing efficient and effective LIMS in China is data sharing and coordination. Duplicated efforts are common everywhere, which not only wastes limited resources provided, but more 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. The research conducted an experimental study to identify and analyze the possible errors in the data conversion, which can help reduce the errors.|
