The Lands Department today launched the 3D Visualisation Map dataset of Kowloon Central and an online application platform Open3Dhk for the public to use free of charge.

To tie in with the development of a smart city, the department started the production of a citywide 3D Visualisation Map in 2021 for release in phases. The first 3D Visualisation Map covering Kowloon East was launched in December 2022.

The Kowloon Central 3D map released today comprises around 9,500 buildings and about 210 individual models of infrastructures, including flyovers, footbridges and subways. It can be downloaded through the Common Spatial Data Infrastructure portal.

Open3Dhk, an online platform transforming a variety of spatial data into user-friendly applications which can support diverse uses by the public, the academia and professionals was also launched today.

Through the interactive functions on the platform, users can view photorealistic 3D city models of Kowloon East and Kowloon Central, building information and the approximate lot boundaries. Users can also plan hiking and cycling routes with the help of the intuitive profiles graphs and gradient measurement tool.

Additionally, the platform provides a first-person view function to enable users to get a detailed understanding of the surrounding environment of a location.

The department said it will continue to promote spatial data to complete the full set of 3D visualisation maps covering the whole of Hong Kong in the third quarter of 2024, adding that more 3D map applications will be provided to the public on Open3Dhk progressively.
