As reported on the Google Earth Blog, Digital Globe is launching a new satellite today, named WorldView I. A similar satellite, WorldView II, will be launching late next year.
Digital Globe is a leading provider of imagery for Google Earth/Maps, so this is a great thing for those products.
It will be a while before we see any new imagery from this satellite (testing, etc), but once it’s live DG says it will be able to acquire data at about seven times the normal rate. This will hopefully mean much more frequent updates in the future.
