> This idea of having software check things is dead in the water,

I accept that people have to make the judgement calls and sign-off, but if the maps are in fact accurate why couldn't the computer at least issue a warning / red flag or similar when there are obvious problems (requested depth within some threshold of the actual depth).

I came across a scenario editor for a land training simulator that didn't provide any way of testing intervisibility between two points. The course authors wasted vast amounts of time when assigning vehicle positions clicking around maps to see if potential targets were in fact visible to the trainees. An auto check would have allowed the course authors to use their expertise to do things that couldn't be automated, building better scenarios faster.
