Read Local GeoJSON Object Example

The following code example takes a locally defined GeoJSON object and parses it into a Bing Maps shape using the GeoJSON module, then adds it to the map. When parsing the GeoJSON object, the options for polygons is set such that they will have a semi-transparent red fill color, a stroke thickness of 5 pixels, and a stroke color of white.

Here is what this GeoJSON object looks like on the map. It is a polygon that outlines a soccer field on the Microsoft campus.
