This one is especially interesting in that I've *never* seen 
anything like this done in sas before :)

A customer asked if there was a way to take a gif image of a map
and use that map in sas - this is what I came up with...

I take the gif image of a geographical map, I find the number of pixels
in the x & y directions (by viewing the 'properties') and use that as 
the "coordinate system" for a SAS map.  
Then 'properties' of this image say the dimensions were 660 by 337 
(660 is in the x/horizontal-direction).

I then create a sas/graph map dataset containing 1 single map area, 
with corners at the same x/y coordinates as the gif map/image
so that my map area/coordinates have the same proportions as the 
CIA map/image.  And I annotate points-of-interest on the map,
by finding the X/Y coordinates of those points by mousing-over
the original map in Paint, and then annotating things onto the
map at those coordinates (with html hotspots/drilldowns).
