About jengmap & our map data
jengmap is built and maintained by Leo Cheung, a CUHK student, to help people make everyday campus journeys. Here is what the map adds, how corrections are handled, and what still needs checking on the ground.
More than a list of buildings
The interactive map joins campus place names, pedestrian connections, terrain and shuttle schedules. Its route comparison helps you consider walking time, climbing, stairs and waiting together. The companion guide connects each place with nearby stops and published facilities so you can plan before opening the map.
The 3D buildings help orient you on a hilly campus; they are simplified shapes, not indoor floor plans. Place pages are built from the same published data as the app. Their estimated walks and nearby distances are planning aids, not promises about an entrance or a building being open.
Where the information comes from
OpenStreetMap supplies map features. Hong Kong Lands Department terrain and the 3D Pedestrian Network help model slopes and walking connections. CUHK sources provide building names, campus facilities and shuttle timetables. Place pages link the published source pages they draw on; the credits page explains licences and image attribution.
These sources answer different questions. A footprint shows a structure exists; it does not establish a public entrance. A timetable lists scheduled service; it does not locate a vehicle. We keep those distinctions when displaying routes and updating information.
How corrections are checked
Reports are compared with retained source geometry and the route that produced the problem. Corrections are made through repeatable data-building scripts rather than drawing an attractive shortcut by hand. Software checks cover graph connections and route geometry; public access and lift operation still require separate on-site evidence.
On 7 October 2026, two reported detours led to restoring source pedestrian links, followed by a wider crossing audit. Four source crossings still had unresolved height conflicts and were not added as usable shortcuts. A shorter computed route is not, by itself, proof that a crossing is safe or open.
Known route-comparison and on-campus verification gaps remain. Follow signs and restrictions, and allow extra time for an unfamiliar journey. jengmap is independent and is not affiliated with or endorsed by CUHK.
Help improve a journey
Use the map’s correction report or email the contact below. Include the place name, start and destination, route option, and what you saw—for example, a closed gate, missing stairs or a relocated stop. A route share link or a photo of a public sign can help. Avoid sending private group links or other people’s personal details.
You do not need an account to use the map. Location is optional. Saved places stay in your browser; Meet groups and Android beta requests have different storage rules described in the privacy policy. Contact us if you need a correction or data deletion.
