Can someone tell me if this qualifies as a trig point?

Cheers, Adriaan

Does it have a Triangulation Station marker at the bottom?

No, nothing except what is in photo, it is cemented into a rock.

It looks more like a marine navigation marker except that it seems to be out in the bush. Is it on the highest point in the area? I don't think it is a trig as I've not seen anything like that before. There would usually be some other markings on the stone as well. Interesting though.

OK, so does it qualify for a Trig Point Listing?

I'm certainly no expert but, IMHO...
It's in a (semi) remote location.
It took a bit of work to get to it.
It looks vaguely like a traditional trig point.
It's listed as a marker.

Therefore, in the spirit of Geocaching Australia's "you make the rules", it's a trig point.

So another variant, I am NZ at the moment and came across some "Volcano Monitoring Equipment" on the slopes of Mt. Taranaki. What I first noticed was the obvious GPS looking antenna on the top. I can only assume it is used to measure any movement that might be going on warning of a possible eruption.

It has a Geodetic Code of PGNE and has been placed by Geonet - information on the network can be found here...

GPS/GNSS receivers determine very precisely positions on the surface of the earth. We compute a daily position for each of our stations so we can track the deformation caused by the interaction of the Australian and Pacific tectonic plates. This is our collection of GPS/GNSS-related data resources and tools.


So while a CORS is designed to track errors in the satellite signal caused by the atmosphere rather than being a trig in it's own right, this system is designed to measure movement. Any thoughts as to if I should add it? It looks similar to the one in the page given though without the solar panels, and is a lot easier to get to than the trig I just published 1200 metres (and 300 metres vertical) up the hill.

It isn't listed as a trig, but it looks similar to other Tasmanian trigs I have seen. So, is it a trig, or just a survey mark. S41 04.447 E145 59.155

The photo says survey mark not trigonometrical station. Looks like a SM to me.

Since then I have found another of those red painted spots, which is listed as a trig and as well as the word survey, it has Primary GPS Station, so I probably should note this next time. 'Red spots' are new to me :).
