Earth in near real time: new Earth monitoring approaches

Since the start of Google Earth in 2001 (it was re-released in 2005 after Google acquired it from Keyhole, Inc ) remote sensing images made their way into every day life. But if you are looking at the images they show on Google Earth or Google Maps: You will see historic data and it strongly depends on companies like Digital Globe, BlackBridge (a.k.a. RapidEye) or Astrium and the contracts with Google whether you will see new or old data.
