GeoJSON for Virtual Earth

For my new project I decided to make use of GeoJSON, a standard for representing geo data in JSON format, rather than returning KML, georss to the client, or some custom format.

From a quick look online there wasn't much in the way of using Virtual Earth with GeoJSON, I found one blog post that was the inspiration behind doing VEGeoJSON.

The VEGeoJSON library provides two functions (not much of a library)

• addGeoJSON(data, onLayerCreated, onShapeCreated)
• getGeoJSON(onGeometryCreated)

As a quick example of its usage

var v = new VEGeoJson(map);
var geoJson = v.getGeoJSON();

VEGeoJSON supports all the GeoJSON shapes; Point, MultiPoint, LineString, MultiLineString, Polygon, MultiPolygon and GeometryCollection.

Thanks to Colin Brown for giving it a quick test and talking me into putting it on CodePlex.
