MapQuest Open API - Comments

MapQuest Open
MapQuest Open API is an OpenStreetMap-based version of embeddable online maps. Using JavaScript or Flex (Flash and Mobile Flash APIs), you can create maps, add controls, plot points and draw lines on the map. The underlying map data, which is displayed as a tiled "slippy" map, is Creative Commons licensed and crowd-sourced by the OpenStreetMap community.
