3D Mapping

Under Government policies and initiatives, the Smart City Blueprint for Hong Kong released in December 2017 set 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.

The 3D Digital Map, which is one of the building blocks of CSDI, is to facilitate opening up and sharing of Government geospatial data. To meet the increasing needs of 3D Digital Map applications and enhance better understanding of multi-level spaces of a modern city like Hong Kong, the Government aims to develop the high-quality 3D Digital Map by phases and strives to cover the whole territory by end 2023.

Lands Department is responsible to explore the 3D mapping technology and to implement the territory-wide 3D digital mapping project.


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.

3D Visualisation Map

The 3D Visualisation Map is a high-quality 3D textured surface model dataset showing topographical and exterior features of terrains, buildings and infrastructures that support visualisation and other geospatial applications.

The dataset in machine-readable formats are now available for previewing and downloading on the Hong Kong GeoData Store and the Public Sector Information Portal.

3D Pedestrian Network

In line with the Smart City initiative of promoting walkability and connectivity, the 3D Pedestrian Network (the Network) was designed to support navigation services and meet the special needs for people with disabilities.

The dataset in machine-readable formats are now available for previewing and downloading on the Hong Kong GeoData Store and the Public Sector Information Portal.

Vehicle-based Mobile Mapping System

In 2017, Lands Department introduced the Vehicle-based Mobile Mapping System, which comprises 3D laser scanner, spherical cameras, GNSS receiver, inertial navigation system and distance measurement indicator mounted on a vehicle. 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.
