Topo: an interactive 3D topographic map maker

Topo is a free classroom tool for teaching topographic maps. Sculpt hills, valleys and volcanoes in 3D and watch the contour map draw itself beside the model.

Raise, lower, smooth and flatten the land, or start from a hill, valley, ridge, saddle, volcano or basin
Explore real places such as Mount St. Helens, the Grand Canyon, Mount Fuji and Mount Everest
Draw a cross-section (profile) between two points, flood the land and watch rain run off into streams
Print maps and worksheets with answer keys

Topo needs JavaScript and WebGL to draw the 3D model and map. Privacy
