triangulation

A surveying technique in which a region is divided into a series of triangular elements based on a line of known length so that accurate measurements of distances and directions may be made by the application of trigonometry.

The network of triangles so laid out.

The location of an unknown point, as in navigation, by the formation of a triangle having the unknown point and two known points as the vertices.

The establishment of a political position that differs from two existing or opposing positions, especially in being moderate.

A making triangular; formation into triangles.

The operation and immediate result of measuring (ordinarily with a theodolite) the angles of a network of triangles laid out on the earth’s surface by marking their vertices.

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.

A technique in surveying in which distances and directions are estimated from an accurately measured baseline and the principles of trigonometry

The network of triangles, so obtained, that are the basis of a map or chart
