The Government developed the Common Spatial Data Infrastructure (CSDI) Portal for the integration, exchange, and sharing of geographic spatial data in support of smart city development in Hong Kong. The CSDI Portal is launched in December 2022.

Datasets released on CSDI Portal are geo-tagged, accompanied with their metadata documents and data specifications and in open and machine-readable formats with Application Programming Interfaces to facilitate innovative use of the spatial data. 

Architectural Services Department published the annual spatial data plans to set out the datasets released and to be released in the respective three years on the CSDI Portal (URL).
