About Data.One

Data.One is a portal to facilitate the wider dissemination of Public Sector Information (PSI) for value-added re-use.  

We believe that PSI is not only a valuable source of reference, but may also generate valuable applications.  Facilitating value-added re-use of PSI will be conducive to the development of Hong Kong as a knowledge-based economy.

To this end, the Government launched on 31 March 2011 an 18-month pilot scheme (i.e. from 31 March 2011 to 30 September 2012) to make available via Data.One geo-referenced public facility data and real-time traffic data for free download and value-added re-use by the public.

The geo-referenced public facility data include names, addresses and co-ordinates, etc. of public facilities such as government offices, hospitals, schools, country parks as well as recreational, cultural and sports venues. Real-time traffic data of the main roads include the average traffic speeds of the main roads in Hong Kong, average cross-harbour journey time between Hong Kong Island and Kowloon, the latest special traffic news and snapshot images of real-time traffic situation.

All these data are freely downloadable and re-usable during pilot scheme and some are in the XML format for convenient data transfer and processing by computers.  Please refer to the guidance on download and the Terms and Conditions of Use for more details.

We cordially invite you to visit Data.One and explore the portal in greater depth!

Last but not least, we treasure your feedback and suggestions for us to improve our service continuously.  Your comments on Data.One will help us consider the overall policy for the dissemination of PSI for value-added re-use in Hong Kong.
