FUNDAMENTAL SURVEYING Traversing and Coordinate Geometry 3

Question 1

What is the Double Meridian Distance (DMD) of the first course in a traverse?

Accepted Answer

Equal to its departure

Answer

Equal to zero

Answer

Equal to its latitude

Answer

Equal to the DMD of the previous course

Question 2

If the total area by DMD computation yields a negative value, what does this indicate?

Accepted Answer

The traverse courses were listed in a clockwise direction

Answer

An error in angle measurement

Answer

The traverse has a misclosure

Answer

The latitudes were computed incorrectly

Question 3

What is 'resection' in plane surveying?

Accepted Answer

Determining the position of an unknown point by observing angles to three or more known control points

Answer

Laying out a curve between two tangents

Answer

Setting out a building boundary from coordinates

Answer

Measuring angles from two known points to a new point

Question 4

What is 'intersection' in plane surveying?

Accepted Answer

Determining the position of an unknown point by observing from two or more known stations

Answer

The crossing of two survey lines

Answer

Measuring the interior angle of a traverse

Answer

Computing the bearing of a traverse leg
