Test: Surveying- 4 - Question 6

Select the correct statement.

Detailed Solution for Test: Surveying- 4 - Question 6

Explanation:

A contour is not necessarily a closed curve: Contours can be both closed curves (such as circles or closed loops) or open curves (such as lines). Contours represent lines of constant value (elevation, temperature, etc.) on a map or a surface, and they can be open or closed depending on the terrain or feature being represented.

A contour represents a ridge line if the concave side of lower value contour lies towards the higher value contour: This statement is correct. In topographic maps, contour lines are used to represent different elevations. When a contour line curves inwards (concave) toward a higher elevation, it indicates a ridge line.

Two contours of different elevations do not cross each other except in the case of an overhanging cliff: This statement is also correct. Contour lines represent lines of constant elevation, and they never intersect or cross each other unless there is an overhanging cliff or an error in the map representation. Contour lines that cross would indicate conflicting elevations, which is not possible in a proper representation.

Test: Surveying- 4 - Question 13

The process of determining the locatins of the instrument station by drawing resectors from the locations of the known stations is called

Test: Surveying- 4 - Question 14

The methods used for locating the plane table stations are
1. radiation
2. traversing
3. intersection
4. resection

The correct answer is

Test: Surveying- 4 - Question 15

If in a closed traverse, the sum of the north latitudes and also the sum of west departures ismore than the sum of the east departures, the bearing of the closing line is in the

Detailed Solution for Test: Surveying- 4 - Question 15

In a closed traverse, the sum of the north latitudes represents the total displacement in the north direction, and the sum of the west departures represents the total displacement in the west direction. Similarly, the sum of the east departures represents the total displacement in the east direction.

If the sum of the north latitudes and west departures is greater than the sum of the east departures, it means that the net displacement in the north and west directions is greater than the net displacement in the east direction. This indicates that the closing line of the traverse is pointing towards the northwest (NW) quadrant.

Test: Surveying- 4 - Question 16

Consider the following assumptions of Bowditch Method:
1. Error in linear measurements are proportional to √l
2.
Correction to latitude or departure of anyside = Total error in L (or) D x Length of that side / Perimeter of traverse
3. Angular Measurements are more precise than linear Measurements
4. Linear Measurements are more precise than angular measurements

Detailed Solution for Test: Surveying- 4 - Question 16

Bowditchs rule is used to balance a traverse when the linear and angular measurements are equally precise.It is assumed that angular and linear meaurements errors are proportional to 1/√L and √L respectively.
