# OpenLayers Measure Example

Demonstrates the measure control to measure distances and areas.

- navigate
- measure distance
- measure area

* Note that the geometries drawn are planar geometries and the metrics returned by the measure control are planar measures. The "great circle" distance does not necessarily represent the length of the segments drawn on the map. Instead, it is a geodesic metric that represents the cumulative shortest path between all vertices in the geometry were they projected onto a sphere.
