|return type||Object ( GeoJSON Polygon )|
|syntax||$.geo.buffer( Object point ( GeoJSON Point ), Number distance )|
var circle = $.geo.buffer( point, 20 )
The buffer method creates a new shape by applying a buffer around an existing shape.
The distance argument is in non-geodetic map units. If you are using geomap with its default map service, it is in meters because the default projection is web mercator meters. If, for example, you are working in a different projection such as NAD83 / New Jersey feet, this function will buffer the shape by feet.
Currently, jQuery Geo will only buffer Point objects into circle Polygons.
This function is similar to Geometry.buffer in JTS.
