Bearing of Course AB
Bearing of Course AB
The direction of course AB, measured clockwise from north, represented in degrees, minutes, and seconds (DD MM SS).
Azimuth of Course AC
Azimuth of Course AC
Bearing of AC, measured clockwise from North. Crucial for surveying and mapmaking.
Coordinates (X,Y)
Coordinates (X,Y)
A point's location in a rectangular coordinate system - X represents east/west, and Y represents north/south; measured in units such as feet.

Study Notes
Test Problems - Surveying
-
Problem 1 (Bearing): Given coordinates of points A and B (1535 S, 1505 W and 435 S, 900 W respectively), calculate the bearing of course AB in DD MM SS format. The bearing is N28°48'34"E.
-
Problem 2 (Traverse): Data from an open traverse is provided (courses, bearings, and distances).
-
Part A (Azimuth): Calculate the north azimuth of course AC in DD MM SS format. The answer is S2°54'38"E.
-
Part B (Coordinates): Given coordinates of point A (X = W200, Y = N150), calculate the coordinates of point C. The results: X = W194.15, Y = S889.45.
Additional Problems
-
Problem 3 (Clockwise Angle): Determine the clockwise angle BAC in DD MM SS format, given departure and latitude data (AB and AC). The angle is 70°46'49".
-
Problem 4 (Traverse Closure): Latitude and departure errors in a closed traverse are provided. The sums of horizontal distances is 6125.85 ft, and precision is 1:10,000. Calculate the Linear Misclosure (LM) and determine if the traverse should be accepted. LM = 0.6364 ft. Precision is 1:9625. The survey should not be accepted.
-
Problem 5 (Distance): Given azimuth and distance data for lines connecting points (e.g., from point 6 to 3), find the distance between point 6 and 3. The distance is 193.28 ft.
-
Problem 6 (Polygon): A five-sided polygon has latitude and departure errors. The perimeter is 1478.94 ft. Calculate the latitude correction for course BC, given a measured length of 350.48 ft. Latitude Correction is +0.047 ft.
