Hong Kong GeoData Store

The Hong Kong GeoData Store is an official open data portal of the Hong Kong Special Administrative Region Government, operated by the Office of the Government Chief Information Officer (OGCIO). It serves as the central repository for geospatial data and geographic information generated by government departments and public bodies in Hong Kong, providing free public access to spatial datasets for a wide range of research, planning, and commercial applications.

History and Founding

The GeoData Store was established as part of the Hong Kong Government's commitment to open data and smart city initiatives, particularly following the adoption of open data policy frameworks in the 2010s. The platform consolidates geospatial datasets that were previously scattered across different government departments, making them accessible through a single standardized portal aligned with international open data standards.

Collections and Holdings

The portal hosts hundreds of geospatial datasets covering topics including land use, building footprints, transport infrastructure, utilities, administrative boundaries, topographic data, environmental monitoring, and natural resources. Datasets are provided in standard geospatial formats including GeoJSON, Shapefile, KML, and CSV. Data is updated at varying frequencies depending on the dataset, with some provided in near-real-time. The platform also provides access to base maps and imagery derived from official government mapping.

Access and Usage

The GeoData Store is freely accessible online at geodata.gov.hk. Users can browse, search, download, and in some cases stream datasets through standard APIs. The platform supports developers, urban planners, environmental researchers, academics, journalists, and the general public. An API allows programmatic access to datasets for integration into applications and analytical tools, and data is available in both English and Chinese.
