I have basic WMS layer and vector layer in OpenLayers. Using EditingToolbar I can draw some features as shown below

enter image description here

Then I want to get some information (like distance and extent) of drawn features in any format. At the movement I stuck on above point. Can you give me some tips or sample code or some links?


you can get vector layer extent:


for getting features:


for getting first feature geometry:


for getting centroid of your first feature:


for getting first feature coordinate as string:


for getting distance one point to another (it cant give geodetic result):

var p1 =   new OpenLayers.Geometry.Point(10,20);
var p2 =   new OpenLayers.Geometry.Point(30,40);

var distance = p1.distanceTo(p2)

  • What's the equivalent of vector.features[0].geometry.x in OpenLayers 3? – user1919 Nov 26 '15 at 12:03

Use a SelectFeature control, and listen to featureselected events on the layer. The listener can use event.feature.geometry.getArea() to get the selected polygon's area, for example.
