topoMap

tools for measuring the Earth

Use these tools to measure the size and shape of geomorphic landforms.

Instructions: Use the map to find interesting landforms. Click on the map to add markers. The graph will show the topographic profile of the line that you trace. The 'Path Information' window will tell you the length of the black and orange lines, the area of the region that they enclose, and the slope of the two lines. By tracing along meandering streams, you can measure the sinuosity of the stream.
