Trigonometric Stations and Survey Plates

Travelling around Australia the design of Trigonometric Stations or ‘Trig’ varies from state to state. Trigs are often in the form of a metal structure, wooden structure, concrete pillars, concrete pillars with vanes, bronze survey discs set in stone or a stone cairn. Stone cairns vary from a loose pile of rocks to substantial or complex structures 2 or 3 metres high. Trigs are well-known as collectables to geocache treasure hunters.

  1. Hi Andrew. As a Land Surveyor I have to say that I am pleased to have found this page about Survey and Trigonometric marks along with the radio related things. I have seen a lot of them (and used) during the field work but I never took a photo…….shame. Best regards, Al, CX8AT

    • If all VK3 activators would visit Little Joe in 2016, you may end up with a sizable cairn?!? Lets start a campaign for ‘Little Joe Cairn’. 🙂
