they get those signs on footy fields to look square on the tele? You know, when you look at the footy field and there is a logo for OBT or whatever painted on the grass? :dry:
I’m a surveyor for those who don’t know – we measure stuff for those who don’t know what a surveyor is! We have just been asked to do a survey for the City Country NRL game in Orange so that they know the angles from the camera to the ground at various points. 
Apparently the info gets sent to South Africa (not kidding, this is fair dinkum) then the sign layouts are worked out there and sent back to Aus so that they can be painted on the fields!
I was fascinated that it was quite that technical! Interesting eh!
