Whereas in ../democd26/indigo2.htm
I screen-captured a Google satellite image,
and then determined the x/y positions to overlay the houses
and construction image on that screen-capture....

In this example, I download the map tiles directly from the web,
and use true lat/long coordinates for the houses and construction
image based on actual lat/long values (not some arbitrary image
coordinates).  This way, for example, I can plot the data onto
different maps, very easily.

Also, when I re-run the SAS job, it downloads the latest/greatest
satellite (or other) image map on-the-fly.  And the OpenStreetmaps 
images are freely usable any way/anywhere you want to use them 
(whereas Google maps are not).
