[Geodata] LANDSAT-8 sample data of osgeo tutorials and workshops - further supplimentary data

 I think adding the LANDSAT-8 data is a good idea and I take Hamish's point
about the need for coastal data.  I also started thinking about data for
mountainous areas.

Hamish's post also got me thinking about making more updated datasets
available for the same footprint as the NC  dataset.  There is 4 band
digital aerial imagery ( NAIP , USDA  summer 2012 , 1m resolution)  and 3
band  6 inch winter imagery ( State of NC 2010 ortho , possibly 4 band for
 Wake County), etc for the  Raleigh/ Wake County area.  There may also be
higher resolution Lidar data available in the future.

Of course, the more data you add, the bigger the download, or more space
needed on the live-demo iso image.

Would it be a good idea to have a "core" downloadable dataset  at
http://www.grassbook.org/data_menu3rd.php and have a supplimentary download
link for other,  updated higher  resolution data sets for the same
footprint or other specific distinct geophysical environments?
