I thought it would be neat to use SAS to create a map interface,
so I can easily look at the traffic cams on the roads I frequently
drive.  

I found the following dot website interface to all the cams,
but it was a bit klunky/slow to use, and it kept "timing out"
after I'd been on the page for a while, and then I'd have
to select "Wake County" again, etc.  Also, I couldn't tell
from the map which direction the camera was pointing (some of
the camera images have text at the bottom telling what direction
the camera's pointed in, but when a camera is at an intersection
it's difficult to know which road it's pointing down, and also
whether the direction is the "road direction" or the "compass
direction").

So on my map, I scrutinized the camera footage long & hard, 
and determined which direction it was pointing, and then 
created an arrow on my SAS map pointing in that actual physical
direction.  Unfortunately, the next morning I noticed that 
sometimes the DOT changes the view on certain cameras :\

Oh well, consider it a proof-of-concept! :)
If the DOT were to use this SAS software to create their maps,
then when they change the view/direction of a camera, then 
they'd know to change it in the map as well.
