Time for Action – adding features
Let's add some features to a map manually.
- Make a copy of the first example—we'll just need a basic WMS base layer and a vector layer.
- Let's create some features first. To do so, we'll need to make use of the
OpenLayers.Geometry classes. Let's start off by creating a
OpenLayers.Geometry.Point object, passing in a longitude and latitude (type and execute the following in Firebug):
var point = new OpenLayers.Geometry.Point(-72, 42);
- Now that we have a geometry object, we can create a feature object from it. We'll use the
OpenLayers.Feature.Vector class to create a feature object using the
point object ...
