Last week MapQuest announced the addition of aerial imagery to the the tile sets they provide through their open tiles service. Today, we're excited to announce a new Community Edition of the Suite that provides access to these beautiful imagery and OSM layers in GeoExplorer.
GeoExplorer is configured by default to allow the addition of these MapQuest layers. You can access them (along with other layer sources) through the "Add Layers" dialog.
The OpenStreetMap layer is particularly useful in layering your own thematic data over MapQuest's rendering of OSM data.
MapQuest make things easy for developers by not requiring an API key to use these newly available layers in their applications. Thanks to MapQuest for providing access to this data.
