These "tiles" can be downloaded using the World Wind Map Tile System. A temporary PHP script was set up at mcfly.com to convert latitude and longitude to appropriate tile requests. See for example http://www.mcfly.org/coord/27.975472/-82.53325, which lists tiles for the Tampa International Airport at (27.975472, -87.53325).

To download this information you need to use WMS.

Mirrors have been set up to divert some of the load from the NASA servers. See http://www.worldwindcentral.com/wiki/Mirrors for the current list of mirrors.

Some mirrors are designated "Type A Servers". These servers must be able to host at minium:

In order to be considered a Type A Server, there are also the following requirements:

Also preferred are the following:

+[[Mirror]]s have been set up to divert some of the load from the NASA servers.  See http://www.worldwindcentral.com/wiki/Mirrors for the current list of mirrors.
+==Type A Servers==
+Some mirrors are designated "Type A Servers".  These servers must be able to host at minium:
+*[[NLT Landsat 7]] imagery: 100 GB
+*[[SRTM30 US DEM]]: 12 GB
+*[[SRTM90 World DEM]]: 13 GB
+*[[Graphical Elevation Data]]: 4.2 GB
+In order to be considered a Type A Server, there are also the following requirements:
+*minimum 20 megabits bandwidth
+*A RAID array
+*Enough space to hold at least the four datasets specified above
+*Shell access (user)
+*A File system that can handle Millions of files (We use [[ReiserFS]] and [[UFS]])
+Also preferred are the following:
+*A server dedicated to World Wind's use
+*24x7 on site staff
+*Extra space is preferred for extra data
