Fsatest or shortest ? Neither! One with views.
Source of information?
Route planning software is based on vector information. This can be some commercial based information (Garmin, Tom Tom, Google etc) or free (Open Street Maps).
Whatever the information it is bound to include errors and omissions.
Manipulation of that information?
This would be the program/application.
This too may include errors and omissions.
Available options?
Some software has the ability to try and avoid or select things - like toll roads, motorways, smaller roads. It may also have the options of fastest route or shortest route.
--------------------
I'm yet to find the options I'd like;
least traffic
scenic
natural beauty spots ( UN listed + others).
Windy roads tend to follow the landscape - making for views. They tend to be slow and long - the opposite of what routing software looks for. So for me, the routing software gives the way most commuters would go, not a tourist route.
