---------------------------------------------------------------

This example is just a proof-of-concept, based off the following
map I saw on the web (which also might not be a real/accurate 
DirecTV map :)

   DirecTV Map (which is gone now)

The annotated circles represent the satellite coverage, and
areas covered by more than one satellite appear darker (via 
the SAS 9.3 alpha-transparent colors used).


In this example, I use the city zipcode as the center of the 
circles (and look up the longitude/latitude for that zipcode
in the sashelp.zipcode table).

I specify the radius of the circle to try to correspond
to the ones in the map (above), but I don't have the real
data about the size/area of the coverage.

Like I say - this is just a proof-of-concept, and should
not be taken as more than that 8)

Someone with the real data & insight into the coverage 
areas could easily modify this example, to produce a 
"real" and fairly accurate map.
