Question

Which of the following height indicators is described as being 'generally more accurate than spot heights'?

• A. Contour Lines
• B. Triangulated Height
• C. Bench Mark
• D. Form Lines

Answer 1

Answer:

B. Triangulated Height

• Because they are based on trigonometric surveys, they offer higher precision than standard spot heights. • A Triangulated Height is an altitude determined through triangulation, a mathematical process of finding a distance or height by forming a triangle to it from two known points. • Unlike a spot height, which might be a one-off measurement of a specific feature, a triangulated height is part of a rigid mathematical grid that spans an entire region.
