Triangulation   Listen
Triangulation  n.  (Surv.) The series or network of triangles into which the face of a country, or any portion of it, is divided in a trigonometrical survey; the operation of measuring the elements necessary to determine the triangles into which the country to be surveyed is supposed to be divided, and thus to fix the positions and distances of the several points connected by them.

... to visit it last year, but the loss of Mr. Cunningham, the consequent delay of the party, and the adverse nature of my instructions in regard to my own views, together prevented me. I then saw that the hills along the line I was now about to follow were favourable for triangulation; but the greater certainty of finding water in a large river like the Lachlan was my chief inducement for now moving towards its banks, as the season was of such unusual drought. On this day's journey I took ...

The northern crater, which is not the largest, was found by the triangulation to measure, externally, no less than three miles and one-eighth of a mile in diameter. Over the lips of these great, broad caldrons, and from little orifices near their summits, deluges of black lava have flowed down ...
