Topographic Map of Hong Kong
Pearl River Delta, China · 22.2800° N · 114.1600° E
Hong Kong packs one of the world's densest skylines onto a thin coastal shelf beneath steep green peaks that rise straight from the harbour. Victoria Peak climbs to 552 m directly above the towers of Hong Kong Island, and the terrain leaves almost no flat ground for the city.
The terrain around Hong Kong
Victoria Peak dominates the island's spine, dropping sheer to Central and the harbour, while across the water the Kowloon hills and Lion Rock wall in the peninsula. Reclaimed flats hug the shoreline; everything else is slope. On the map the harbour reads as a clean open channel bracketed by tight, near-concentric contours packing up the peaks on both sides.
How this map was made
Every contour line traces a constant elevation drawn from public SRTM 30 m radar data, extracted with a marching-squares algorithm at a 50 m interval and coloured by height — cool blues in the valley climbing to warm reds on the summits. The satellite base layer and the contours share the same Web Mercator projection, so the lines fall exactly on the ground they describe.
