Trigonometric beacons

Unread postby arks » Sat Jan 24, 2009 9:06 pm

I saw this "beacon"-like structure along the H1-4 between the S90 ans Satara. It's on the righthand side as you head suth towards Satara. Does anyone have any idea what it is or what it is for?

Probably a radio mast of sorts.

Hi Arks,

It is a trigonometric beacon placed by the Surveyor General. There is a network of about 27 000 trig beacons around South Africa.

This specific one is No. 235923 47WITPENS.

It was placed on a tower to allow it to be seen from a greater distance in this relatively flat area.

They are used for accurate map plotting by surveyors, adventurers and the Military.

Thanks for this very interesting information, BigMan. 8) I'd seen similar beacons in KTP last year and wondered about them then as well. I'm glad that I finally asked about them! Also curious now about how you happen to know the specific ID of that particular beacon? :shock: :? Are you a surveyor perchance?

Not surveyor but ex-military.

The specific ID's of these beacons are available as an add-in database on my GPS software.

I know there is another one in the south of the park around the Hippo Pools/ S25 area.
Thanks for the info BIgMan. :thumbs_up:

I think some were also erected specifically as part of a fire monitoring program .
Am I correct ?
KNP is sacred. I am opposed to the modernisation of Kruger and from the depths of my soul long for the Kruger of yesteryear! 1000+km on foot in KNP incl 56 wild trails.200+ nights in the wildernessndloti-indigenous name for serval.

Agree with bigman.
They are normally placed on a highpoint but if there aren't any, one had to be be created.

Ndloti, you may be correct. :hmz: I have seen a number of similar (but a lot bigger) towers in the Eucalyptus and Pine plantations around Barberton, Sabie and Nelspruit.

These plantation towers are also erected at high points to allow the best view and are manned during the hight of the fire season as far as I know.

It is just possible that some of these towers also house a trigonometric beacon, although I am guessing here. :?:
