==Datasets available==
Low resolution Blue Marble datasets are included with the initial [[download]]; as a user zooms into certain areas, additional high resolution data is downloaded from the NASA [[Server (computing)|server]]s. The size of all currently available data sets is about 4.6 [[terabytes]].
