It's only my personal opinion, but I think that hand-drawn plans and sections look far better than ones done purely digitally. In many ways, this is based on aesthetics (I just think that they look nicer), but as both are to some extent dependent on the interpretation of the surveyor, I'm not convinced that the digital versions are necessarily any more accurate - after all, if the edge of a feature or layer is determined to within a couple of centimetres, that's probably accurate enough for most purposes, so the sub-millimetre accuracy of the GPS unit used is probably not hugely significant. I'd suggest that GPS is probably more useful at a larger level, in ensuring that any site plans (whether hand-drawn or digital) can be accurately tied into the national grid.
