I had never believed that maps could calculate for me a practical drive-able route from point A to point B in the real world. Earlier this year, just for the fun of it, I asked Google Maps the route from where I was in town to home. I was surprised! It knew where the U-turns were, where I could turn left, and where the ramp into and out of the highway was. It gave the exact route that I was using for years.
The details of the information required for such as feat is complex. I have been left behind on the progress and standards made in the cartographic world.
In the last forty-eight hours, everyone has heard how Apple has bungled up on their maps. I would like to relate an experience with Google maps here to demonstrate some of what it takes to build usable maps.
In April, I had to make a trip to a remote outback of south Malaysia. This was from Google Maps the day before I traveled in April.

The next day, I took a look at Google Maps again, and lo and behold, this is what I got:
|Google Maps AFTER I drove at above 50kph|
How Google crowd sources everyone's inputs to improve their maps is IMPRESSIVE!
Unless, it's a coincidence that Google was updating the maps of south Malaysia that day.
