Spatial data exchange within the HKSAR government : from a perspective of a data agent
So Man Cheong & Ng Wai Tak
Under the Digital 21 Information Technology (IT) Strategy, the HKSAR Government has been making substantial progress towards making Hong Kong a leading e-business community and digital city in the globally connected world. The Lands Department (LandsD), as the primary digital map data supply agency in Hong Kong, is in the position to help the establishment of the Hong Kong Spatial Data Infrastructure (HKSDI). As a first step, a project namely The Implementation of Data Alignment Measures (DAM)) has commenced in early 2004 aiming at improving the efficiency and effectiveness in exchange of spatial data among government departments and at addressing deficiencies arising from data definition, compatibility of data format, data quality, data cost and turn around time (HPLB, 2004a). Under the DAM project, LandsD has been assigned to be the Data Agent of three Common Spatial Units (CSUs) (namely, Building, Lot and Road Centreline) and is responsible for the related spatial data collection, creation, conversion, integration and dissemination. LandsD has been carrying out continuous enhancements and revamping work including both technical measures and administrative controls relating to the spatial data.
