Hello,
Is there a simple means of generating a random spatial offset (Vector?)
for obfuscating the position of a point?
I imagine this offset could be stored in one spatial column and then
added to a real point in another column to move its position by the offset.
Points for which no 'obfuscation' is needed would have a zero offset value.
Another means might be to reduce the horizontal accuracy of the point,
this might be the simplest means if all points could be treated the same
way, but this is not possible.
