Common Spatial Data Infrastructure portal and first 3D digital map open for use
     The Development Bureau and the Lands Department (LandsD) today (December 29) launched the Common Spatial Data Infrastructure (CSDI) portal (portal.csdi.gov.hk) and the first 3D Visualisation Map dataset for the public to use free of charge.

     The CSDI is a key initiative under the Smart City Blueprint for Hong Kong. It provides a map-based digital infrastructure as a one-stop platform to open and share the Government's spatial data. By allowing members of the public to search, view and download various kinds of spatial data from the portal, a wide range of possibilities for application development will be opened, the digital economy boosted and quality of life improved.

     Over 500 spatial datasets from various government departments will be made available through the portal, covering different aspects such as planning, lands, buildings, works, population, transport, etc. Framework Spatial Data Themes, such as "Building", "Land Parcel" and "Address", are also available on the portal to provide location references for other datasets. 

     Also released to the public via the portal from today is the first 3D Visualisation Map dataset developed by the LandsD. The dataset covering the Kowloon East region comprises individualised models of about 6 500 buildings and about 420 infrastructures including flyovers, footbridges and subways. The release of the 3D digital map signifies that map production in Hong Kong has risen from 2D digital maps to a new level. 

     The 3D digital map can support a wide range of functions including urban planning, land management, project development, environmental studies, traffic studies, landscape design, as well as other technical assessments. It also promotes the development of various applications and enables users' better grasp of the spatial information of a specific location. The LandsD will continue to press ahead with the development of 3D digital maps for other regions and release them for public use upon completion. 

     The Government will keep the measures under review and strive to share more spatial data to suit the needs of the community. For latest information of the CSDI, please visit the thematic website (www.csdi.gov.hk).
