Topographic map
of Cape Town
Western Cape, South Africa — 50 m contours over bare-earth elevation data.
Cape Town wraps around the base of Table Mountain, whose flat 1,085 m summit and sheer sandstone faces dominate the city bowl. The peninsula's mountains meet the Atlantic on both sides, giving the contour map an unmistakable silhouette.
Table Mountain's near-vertical cliffs crowd the contours into an almost solid band, flanked by Devil's Peak and Lion's Head. South of the city the chain continues down the Cape Peninsula toward the Cape of Good Hope, hemmed by ocean on the west and False Bay on the east. The map reads as a spine of dense relief between two coastlines.
How this map was made
Every contour line traces a constant elevation drawn from the public GEDTM30 30 m bare-earth terrain model, 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.
