With its wealth of Geographic Information System (GIS) expertise, Lands Department develops and provides handy web-map service portals to users across Government Bureaux/Departments (B/Ds) as well as the general public as follows.
The CSDI Portal was launched in December 2022 as the government initiative to support the development of smart city in Hong Kong. Its goal is to serve as an one-stop spatial data portal for different stakeholders to discover, interpret, share, and reuse the diverse spatial data for developing smart applications.
The Common Spatial Data Infrastructure (CSDI) Use Cases transform geospatial data from the CSDI Portal into practical and insightful information, thereby demonstrating the utility and potential of open spatial data. The Use Cases comprise the three geospatial applications, including Walkin’HK, Storytelling Application and District-based Spatial Information Dashboard:
Walkin’HK utilises 3D spatial data to analyse walkable zone and nearby community facilities, the application provides a diverse range of walking routes. It highlights the versatility of geospatial data analysis while deepening public understanding of the “Walkable City” concept.
Storytelling Application themes around the “Blue and Green Recreation, Tourism and Conservation Circle” in the Northern Metropolis, this application employs an interactive storytelling approach to familiarise the public with the practical applications of geospatial data.
District-based Spatial Information Dashboard features a user-friendly, interactive data visualisation tool, this dashboard displays district-related spatial data analysis results, enabling the public to gain a more intuitive and comprehensive understanding of geospatial information.

GeoAddress Finder helps users to search and locate GeoAddress, a standardized common location identifier developed under Address Data Infrastructure (ADI), for a corresponding building or address. The standardized location identifier facilitates the interoperability of address information across Government and the community.
The following major functions are provided:
GeoAddress Finder is developed with Address Lookup Service (ALS). ALS is a web service providing lookup function on Hong Kong address records in both Chinese and English aggregated from various Government Bureaux/Departments. For the coverage of ALS, please visit Open Data Portal.
The Geo-tagging Tool is a web application that helps users to convert textual and non-spatial data (e.g. demographic data) into a form of spatial data for displaying on a digital map and further development of geospatial applications. The Tool supports users to:

To demonstrate the potential application of 3D Visualisation Map and spatial data CSDI portal in December 2022, “Open3Dhk” transformed a large variety of spatial data into user-friendly applications which can support diverse users by the general public, the academia and professionals. Through the interactive functions on the platform, users can view and measure 3D Visualisation Map, 3D Indoor Map and panoramic street-level imagery (Streetscape 360), building information, approximate lot boundaries and other real-time spatial data.
The GeoInfo Map is a public web map service which was launched in May 2010. It provides free and convenient public access to accurate maps of Hong Kong, as well as providing the location and related information about various public facilities and services. It enables government departments to release to the public their latest geospatial data with satisfactory system performance and user experience. The public can conveniently access digital maps using various platforms, including tablet computers and smartphones, as well as integrate various geospatial data for different applications.
LandsD launched the HKSAR Geospatial Information Hub (GIH) in 2004, to support the internal operation and information sharing within the Government. Through the GIH, geospatial data and related information collected from various departments can be effectively distributed and shared across the whole government.
LandsD has been collaborating with different government B/Ds in making GIH an ideal platform for disseminating geospatial information with the aim of delivering better public services. Advanced functions in the GIH, including spatial analysis and trend display functions, have been developed to facilitate efficient visualisation and retrieval of spatial data by officers in government departments. This facilitates their daily work and decision-making processes, thus enhancing their services to the public.
Hong Kong Map Service 2.0 (HKMS 2.0) is a one-stop platform providing round-the-clock service for ordering and downloading digital map products, paper map products and cadastral survey records to the public.
For enquiries related to map products, please contact Map Publications Centre at (852) 2231-3187 or send an email to hkms_pub@landsd.gov.hk.
"MyMapHK" is an "All-in-One" mobile map app, which provides public with a convenient and on-the-go access to the official maps published by the Lands Department and integrated geospatial information about public facilities in Hong Kong.
Download the app for FREE from the App Store, Google Play or Huawei AppGallery!

Lands Department provides several HTTP-based APIs for application developer to query and retrieve spatial data. These APIs enable developer to integrate LandsD's digital map with their map application.
The general public can obtain more information of APIs from Common Spatial Data Infrastructure (CSDI) Portal.
For users of Government Department, please visit Map API portal for Government Departments.
