To use this model you will need a modest PC with a decent graphics car - 1GB memory on the graphics card would be useful!

This model may be opened in Google Earth using FILE -> OPEN-> and selecting the .kmz file. To load the legend 
open the .txt file in a text editor (i.e. Notepad) and correct the path pointing to the legend.jpg file. 
Then select all of the text, copy, select 'My Places' in Google Earth, and paste.
