3D Digital Map
The Smart City Blueprint for Hong Kong released by the Government in December 2017 sets out the overall framework and strategy for developing Hong Kong into a spatially enabled smart city including the adoption of Building Information Modelling (BIM) and the development of Common Spatial Data Infrastructure (CSDI) and 3D Digital Map.
In March 2025, the Lands Department fully launched the 3D Digital Map covering the whole territory of Hong Kong. The 3D Digital Map greatly facilitates the opening up and sharing of Government geospatial data, and serves as the core digital infrastructure for the development of Hong Kong as a smart city.
3D Visualisation Map
The 3D Visualisation Map (Individualised models) are a set of digital data of 3D models featuring geometry models and texture maps to represent the geometrical shape, appearance and position of different types of ground objects, including building, infrastructure, vegetation, site, waterbody, terrain and generic (others). The dataset covers the entire territory of Hong Kong. You can access the 3D Visualisation Map on the online application platform "Open3Dhk", or download the dataset through the Common Spatial Data Infrastructure Portal.
The 3D Visualisation Map (Non-textured models) are a set of digital data of 3D models featuring geometry models to represent the geometrical shape and position of different types of ground objects, including building, infrastructure and terrain. The dataset covers the whole territory of Hong Kong. You can access the 3D Visualisation Map on the online application platform "Open3Dhk", or download the dataset through the Common Spatial Data Infrastructure Portal.
The 3D Visualisation Map (Tile-based models) are based on the mesh model made from oblique aerial images. The dataset covers the entire territory of Hong Kong. You can access the 3D Visualisation Map on the online application platform "Open3Dhk", or download the dataset through the Common Spatial Data Infrastructure Portal.

3D Indoor Map
Lands Department conducts pilot project to generate 3D Indoor Map covering 1,250 buildings of Hong Kong, Kowloon, New Territories and Islands.
The 3D Indoor Map empowers the 3-dimensional interior layout of a building with GIS-enabled capabilities for 3-dimensional visualization, asset management, tourism and smart applications.
To integrate with Lands Department's 3D Visualization Map and 3D Pedestrian Network, the 3D Indoor Map features precise dimension, floor locations, units, point-of-interests. It also includes entry and exit points, providing an immersive experience of indoor simulations. Additionally, it captures look and feel of the outdoor environment for a comprehensive view.
The 3D Indoor Map transforms traditional floor plans into a digital format, enabling the organization to plan and utilize indoor space effectively. Its dynamic and interactive representation not only simplifies wayfinding, but also enables the demonstration of the indoor environment through technology like augmented reality, virtual reality or extended reality.
3D Pedestrian Network
In line with the Smart City initiative of promoting walkability and connectivity, the 3D Pedestrian Network has been designed to support navigation services and accommodate the needs for people with disabilities.
The dataset in machine-readable formats are now available for preview and download on the CSDI Portal and the Open Data Portal.

3D Spatial Data (Series: 3D-BIT00)
3D Spatial Data is a set of territory-wide digital 3D model data created to represent the shape, appearance and position of various types of ground features including building, infrastructure and terrain. In this dataset, the 3D models are categorized into seven secondary classes under three primary classes according to their types and level of details as illustrated in the diagram below. The 3D Spatial Data is very useful for many 3D modeling applications such as view analysis for land assessment, 3D animation for presentation of engineering proposals, air ventilation analysis, etc.
For more about the 3D-BIT00 data, you can refer to the Information Sheet on 3D Spatial Data.

Illustrating Different Classes of 3D Spatial Data

Vehicle-based Mobile Mapping System
In 2017, Lands Department first introduced the Vehicle-based Mobile Mapping System (VMMS), which comprises 3D laser scanner, spherical cameras, GNSS receiver, inertial navigation system and distance measurement indicator mounted on a vehicle. Currently, Lands Department processes two VMMS to support 3D mapping. This system can efficiently acquire point cloud data and street-view imagery data for various survey and mapping applications, such as recording topographical information, updating the basic map, producing street view map, 3D digital map, and 3D models with very high level of details. This system provides useful spatial data for the development of the Smart City of Hong Kong. You can view the 360-degree street-level panoramic images covering Hong Kong Island, Kowloon, Lantau and the New Territories with the "Streetscape 360" function on the online application platform "Open3Dhk".
Mobile Mapping System Data
The Mobile Mapping System (MMS) dataset is a set of street-level point cloud and imagery data collected by Mobile Mapping System which supports the creation, maintenance, and enhancement of 3D digital maps. Such data is now available for public access subject to a fee to be charged (which aims to recover the cost of providing the service) and the prevailing terms and conditions of use.
The MMS data consists of high-density point cloud and street-view images using laser scanners and high-resolution cameras. High quality positioning sensors provides accurate positioning to the data.
A sample point cloud and imagery dataset, about 1 GB in size, is available for download and testing at the following link. Before downloading, please read the copyright notice.
Copyright Notice
All point cloud and imagery dataset which are produced by the Lands Department, are the intellectual property and asset of the Government of Hong Kong Special Administrative Region. It is a Government policy to protect all the copyright of these intellectual property and asset. Therefore the point cloud and imagery dataset that are distributed to members of the public should not be disseminated, in part or in whole or in whatever forms or media, to a third party.
