GREarth GOES Details

GREarth displays several sectors of GOES imagery. Three types of imagery are available in each sector: 1km visible, 4km Infrared, and 4km Water Vapor. Each image is downloaded from the GREarth server as multiresolution tiles in order to reduce bandwidth usage. For example, a single CONUS VIS image can be as large as 18MB and can update every 5 minutes; a prohibitive use of internet connection data transfer capabilities. Multiresolution tiling allows GREarth to download only those parts of the image that you are viewing.
