I'm building a web application - my requirements are:
- Must have global satellite imagery.
- Must have easy to use API's that are capable of geoJSON data imports, mouse and keyboard gestures, etc.
To my knowledge Bing, Google and Yahoo are the only companies that supply both of these. Some support the former to an extent; perhaps not global (NASA, third party mapping solutions), and some support the latter (OSM for example)...but few support both.
Are my only options Bing, Google, and Yahoo?
If so, is anyone aware of any ongoing projects (satellites) that are under construction that will eventually be launched and provide global satellite coverage under open source?
