what format distanceTo function returns in OpenLayers?

Question

i am using distanceTo function in OpenLayers Geometry.

http://dev.openlayers.org/docs/files/OpenLayers/Geometry/Point-js.html#OpenLayers.Geometry.Point.distanceTo

here am confused in which format it will return the value. It is in Kilometers or meters?

Answer 1

Meters if your map units are in meters (default).

Correction:

Sorry, default is degrees. map units documentation

Defaults to ‘degrees’. Possible values are ‘degrees’ (or ‘dd’), ‘m’, ‘ft’, ‘km’, ‘mi’, ‘inches’.

But you can change that in your map constructor:

var map = new OpenLayers.Map({
    div: "map",
    units: 'm'
});

You can get the units like this:

map.getUnits();
