I haven't found any reliable sources for the information that you mention. The data that I use right now has to meet a couple of requirements.....these may change in the future, but as of now this is what I need.

1.) Data/Images/Etc that are reliably available. That is, they are always located at the same URL or FTP directory.

2.) They must have some logic in regards to temporal description. Ie., the files must have some sort of naming comvention that indicates their age (2005080400Z.dat), or a file with a set name must be updated in place....ie, daily.dat must be replaced with fresh data regularly.

3.) If dealing with graphics, they must be geolocatable (in addition to the above). The view cannot change from one point in time to the next (NOAA Floater satellite views), unless they are geoencoded images. I've got to be able to tell GoogleEarth where to put these images, and if their view changes, then they won't be aligned properly in GE.

4.) Images must also be projected in a way that it is possible to align them in GE.

By all means, if anyone finds any other relevant data that fits the above, I'll be glad to add it. I search for new stuff regularly, but I'm only 1 person with limited time, so I may miss some good stuff.

Thanks for the kind words hwwtdw.
