# Map legend

This example shows how to use the Legend plugin to add a color legend to the map. Additionally, the example code shows how to read elevation values at specific locations of the map using the `elevationAt` property.

When presenting elevation values to the users, please note that the final elevation at a specific coordinate on the map is a distance-weighted sum of elevations of nearby points. Therefore, even the areas with no points may have non-zero elevations.

If you set the elevation property of each point on the elevations layer to `1.0`, the final map elevation values will roughly correspond to the number of points in the nearest area.
