If you don't mind measuring in the frequency domain, a tunable LC "wire"
can be used to act as an effective short enabling extension of a
specific ground point some distance away (at the resonant frequency
only!). I can't remember who manufacturers this. Has anyone used this

One consequence of noise across ground plane is it can effectively drive
common-mode current on attached cables (Imagine two cables on
opposite sides of the board--hey those look like rabbit ears!) or drive
the cable against the ground plane of the board.
