i found this on wowhead is it posoble to go to the dig site and then take 2 readings x distance from each other like below but use the mesh to find the location if the game outputs derection acuretly it may be easy to farm
1. Walk sideways from the direction the surveyor is pointing
2. Pan the camera and line the surveyor up with the upper edge of the screen, this gives your first vector.
3. Survey from your new position, holding the camera still so as not to lose the first vector.
4. X marks the spot! Just walk in the direction the surveyor is pointing until you cross your first vector (pointing out the intersection with your mouse before you start moving is a good idea).
