A Curve is a MultiPoint, whose points are assumed to be connected. To this end, we provide a “getLength()” function, which iterates through the points, summing the distances between them.

| Functions | |
| getLength | {Float} The length of the curve |
| getGeodesicLength | Calculate the approximate length of the geometry were it projected onto the earth. |
| point | {Array(OpenLayers.Geometry.Point)} |
getGeodesicLength: function( projection )
Calculate the approximate length of the geometry were it projected onto the earth.
| projection | {OpenLayers.Projection} The spatial reference system for the geometry coordinates. If not provided, Geographic/WGS84 is assumed. |
{Float} The appoximate geodesic length of the geometry in meters.
