Azimuth Calculation and Verification

This video tutorial explains how to compute the azimuth of a closed traverse loop in both clockwise and counterclockwise directions. It covers the use of a worksheet to organize calculations, the importance of interior angles, and how to perform checks to ensure accuracy. The tutorial provides a step-by-step guide to calculating azimuths, emphasizing the differences between clockwise and counterclockwise methods.

What is the primary focus of the video tutorial?

• Studying the history of cartography

• Understanding the concept of latitude and longitude

• Learning about different types of maps

• Calculating azimuths in a closed traverse loop

In which direction is the azimuth first calculated in the video?

• North to South

• Clockwise

• Counterclockwise

• East to West

What is the purpose of the worksheet mentioned in the video?

• To record weather data

• To organize repetitive calculations

• To draw the traverse loop

• To measure angles directly

How do you determine if the traversal is clockwise or counterclockwise?

• By checking the compass direction

• By looking at the drawing and azimuth

• By using a GPS device

• By measuring the distance between points

What is the azimuth of the line CD in the clockwise calculation?

• 90 00:00

• 180 00:00

• 360 00:00

• 205 27:53

What adjustment is made if subtracting an interior angle results in a negative number?

• Subtract 90 degrees

• Add 90 degrees

• Add 360 degrees

• Subtract 360 degrees

Why is it important to verify the azimuth calculations?

• To determine the elevation

• To calculate the area of the loop

• To find the shortest path

• To ensure the loop is closed correctly

What is the first step in reversing the azimuth calculation process?

• Add 90 degrees

• Subtract 90 degrees

• Measure the distance

• Find the back azimuth

In the counterclockwise calculation, what is done with the interior angles?

• They are subtracted

• They are added

• They are ignored

• They are doubled

What is the final step in verifying the counterclockwise azimuth calculation?

• Checking the starting azimuth

• Measuring the loop's perimeter

• Drawing the loop on a map

• Calculating the loop's area
