Early in my career, I led a small team to create a product to monitor operations of a physical system. This system was geographically situated in a such a way that different locations were located on a map. The top-level view of the system might refer to different geographic locations (e.g. "First St node" and "Highway 3 node").
This was during the time that Google Earth was New! Exciting! AJAX?! For a prototype, we lifted *the customer's own marketing map graphic* and overlaid a colored disk at each location representing current status.
Two side effects of the prototype demo: first, the sheer wonderment of "how did you get that?! Is it a satellite?! IS IT GOOGLE EARTH?!" Second: "How does it know the status?" "Holy crap! Maple Ave node IS RED ZOMG CALL SOMEONE WHAT DOES IT MEAN?!"
The best part: explaining it was (1) a simple
Seeing is, indeed, believing.
