An example is attached where the Bing Imagery is out by 2 metres in one direction and one in the other. The Trig point is North of its actual location (between the end of its right leg and the low wall) and the roads whilst aligned to the trig point are not aligned to the imagery which is out of kilter.
The Bing imagery in general is not geolocated to much more than a few meters accuracy making the ability to realign important at high magnification.
Also the trig point symbol needs a mark for the centre like crosshairs.
