Abstract: The application of GIS technologies in Hong Kong commenced in the early 1980's within both the government departments and some leading utility companies on an experimental basis with the production of a small quantity of digital data, either scanned or digitized from the paper maps. Since the establishment of the Computerized Land Information System (CLIS) by the Land Information Centre (LIC) of Hong Kong Government in the early 1990's, high quality digital map data covering the whole territory of Hong Kong at different scales are made available to all government departments and members of the public. The scenario has arouse the interest of many local companies and government departments to set up their GIS systems with the use of LIC geographic data to configure their own geographic framework. However, the progress of GIS development in Hong Kong is not entirely straightforward. In particular, many adverse comments on GIS Data Management have been expressed from GIS scholars and practitioners. Their comments focus mainly on the undefined scope of GIS data, lack of user requirement information, lack of data policy, and deficiency of the copyright laws under the British Sovereignty. Many GIS users have also complained about the price of spatial data, especially those saleable by the government departments, are too expensive to be affordable by small investors. This study aims to address various issues of GIS Data Management problems on aspects of user requirements, data policy, data standard, data pricing and laws to protect the spatial data, which have close correlation and influence with each other. A GIS User Requirement Survey was carried out in this thesis to analyze the contemporary needs of GIS users in Hong Kong on the following issues: (1) Business Objective of GIS Users; (2) GIS Software and Hardware; (3) GIS/CAD Software Usage; (4)GIS/CAD Data Application; and (5)User's Comments and Suggestions. From the writer's point of view, the rate of response to the User Requirement Survey from both the government departments and the private sectors has been very satisfactory, and there is noticeable trend that a wide bracket of local users have frequently applied the functions of GIS and CAD systems concurrently in their business activities. Inter alia, many useful comments have been solicited from the respondents reflecting their views on the current GIS data management policies in Hong Kong which were all critically considered by the writer in solving different data management problems throughout the study. In addition, the methodologies and experience of some leading countries in formulating the following spatial data management policies and strategies were critically examined: (i) Spatial Data Policy; (ii) Spatial Data Infrastructure; (iii) Data Transfer Standard; and (iv) Spatial Data Price and Marketing Strategies. The adaptation of overseas methodologies and technologies to formulate the local data standards and data policies require careful filtering and modifications in order to meet the needs of local situation, practice and cultures. This study also aims to investigate the problems and needs of local GIS users in this area. Having examined and compared the pros and cons of some leading countries, for example, Australia, USA and UK, in formulating their data standards and data policies, the writer has made every effort for developing relevant conceptual models for formulating data policy, spatial data infrastructure, data transfer standard, data pricing and marketing strategies etc. to meet the genuine needs of GIS users in Hong Kong. Last but not the least, a case study on a proposed Demographic GIS for the Census and Statistics Department was carried out in this thesis to assess the needs and problems on establishing the system. It is indeed a typical case having potential to consolidate the results of various GIS data management strategies in the design of its system configuration and data entities. Major issues on aspects of User Requirement, Data Policy, Data Exchange Strategies, Laws for Protection of Intellectual Property, Data Pricing and Marketing etc. have been discussed in detail with a view to evaluating the feasibility and significance of applying the data management strategies as recommended in this thesis.
