Color your terrain with elevation gradients

By The TopoLines Team

A single-color contour map is clean, but it hides one thing your data already knows: height. With elevation gradients, every line is colored by its real altitude — so valleys, ridges, and summits read instantly.

From flat to legible

Pick the gradient stroke mode, choose your stops, and TopoLines colors each contour by its baked elevation value. Lowlands fade into highlands across a smooth ramp you control.

Make it your palette

Gradient strokes are a Pro feature — one credit pack unlocks them, and your credits never expire.
