Topographic Map of Bolzano

Bolzano sits at the junction of three valleys in South Tyrol, a low basin at 262 m surrounded by slopes that climb toward the Dolomites. The contrast between the vineyard-covered valley floor and the rock walls above is extreme.

The terrain around Bolzano

The Ritten plateau rises directly north of the city, the Rosengarten and the western Dolomites serrate the eastern skyline, and the Mendel ridge closes the west. The Adige and Isarco valleys meet here as broad flat corridors, so the map reads as a Y of open ground cut into steeply contoured terrain.

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 100 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.

You can regenerate this exact view — and change the interval, colours, resolution or export it as a print-ready SVG — directly in the TopoLines editor.
