The QuadKey plugin is useful for reading web map tile repositories that follow the Bing maps tile system. It is assumed that the dataset is in spherical-mercator with 2x2 tiles at the root just like Bing.

Example usage:

<image name="imagery" driver="quadkey">

Creating the URL template:

The square brackets [] indicate that osgEarth should “cycle through” the characters within, resulting in round-robin server requests. Some services require this.

You will need to provide {key} template within the URL where osgEarth will insert the quadkey for the tile it’s requesting.


url:Location of the tile repository (URL template – see above)
profile:Spatial profile of the repository
format:If the format is not part of the URL itself, you can specify it here.
