Note that this technique is included in the book SAS/Graph: Beyond the Basics,
and all the 'tricks' used to create it are described in great detail!

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 image of a geographical map or floorplan, 
I find the number of pixels in the x & y directions (by viewing the 'properties' in IE, etc) 
and use that as the "coordinate system" for a SAS map.

I then create a sas/graph map dataset containing 1 single map area,
with corners at the same x/y coordinates as the map/image
so that my map area/coordinates have the same proportions as the
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).

I set up drilldown/hotspots (using the annotate "html" variable, with 
html title= charttip/flyover-text and href= drilldown).

Here are several examples that use this technique:

  PNC Center Stadium
  Senate Floor Voting
  Theater Seating Map
  Mexico Geographical Map
  Canoeing Locations onto Google Map Snapshot
  Housing Project #2 onto Google Map Snapshot

Or, taking things up-a-notch on the geographical maps...
here are some examples where I actually devise ways to line 
up images of maps onto a sas map, or annotate lat/longs onto
a map image:

  Lat/Long markers & map borders onto Geological Features image
  Lat/Long markers & map borders onto Topographical Features image
  Lat/Long markers & map borders onto Topographical Features image (dams)
  Housing Project onto Google Map Snapshot
  Peru w/ Geological Map Images
  Peru w/ Satellite Images
