The Lands Department announced today the extension of the 3D Indoor Map and 3D Indoor Network to all Mass Transit Railway (MTR) stations, providing comprehensive spatial data for the benefit of MTR users.

The 3D Indoor Map, developed by the department and the MTR Corporation, previously covered around 30 MTR stations, giving information on points of interest and supporting point-to-point pedestrian route planning within those stations.

The map has now been extended to cover all 98 MTR stations across 10 railway lines, namely the Airport Express, the Disneyland Resort Line, the East Rail Line, the Island Line, the Kwun Tong Line, the South Island Line, the Tseung Kwan O Line, the Tsuen Wan Line, the Tuen Ma Line and the Tung Chung Line. It provides information on the interior layout of publicly accessible areas within stations, including levels, units, shops, points of interest and indoor routes.

To support point-to-point route planning, the 3D Indoor Network captures connections between different parts of stations, linking facilities, shops, entrances and exits, as well as interfacing with the outdoor 3D Pedestrian Network. Based on information contained in the indoor map and the indoor network, the system displays facilities and areas along routes and offers barrier-free route options.

The 3D Indoor Map dataset has been uploaded to the Common Spatial Data Infrastructure (CSDI) Portal for free download. To support application development, the portal also provides multiple Application Programming Interfaces (APIs), including the APIs of the 3D Indoor Map of MTR stations and the 3D Pedestrian Route Search, together with sample codes demonstrating related functions. Users can also browse the 3D Indoor Map and use the point-to-point route planning tool on the online application platform “Open3Dhk”.

Additionally, the department launched the 3D Visualisation Map (non-textured models) in late September. The new dataset covers the whole of Hong Kong and consists of over 220,000 geometric models representing different types of ground features, including buildings and infrastructure. It has been uploaded to the CSDI Portal for free download.
