a method of surveying in which a whole area is divided into triangles, the sides of which are measured, usually by electromagnetic distance measuring for geodetic control or by chain survey for a detailed survey
trilateration in American English
(traiˈlætəˈreiʃən)
noun
Surveying
a method of determining the relative positions of three or more points by treating these points as vertices of a triangle or triangles of which the angles and sides can be measured
Word origin
[trilater(al) + -ation]-ation is used to form nouns from stems ending in -ate (separation) and, on this model, to form nouns from stems of other origin (starvation). Other words that use the affix -ation include: capitalization, concentration, pagination, polymerization, transportation
