    • A.

      Geographic Coordinate System (GCS)

    • B.

      Universal Transverse Mercator (UTM)

    • C.

      North American Datum 1983 (NAD83)

    • D.

      World Geodetic System 1984 (WGS84)

    Correct Answer
    B. Universal Transverse Mercator (UTM)
    Explanation
    The correct answer is Universal Transverse Mercator (UTM). UTM is a projection system that is commonly used to represent the ellipsoid in two dimensions. It divides the Earth into multiple zones and uses a transverse cylindrical projection to map each zone individually. This projection is especially useful for large-scale mapping and navigation purposes, as it provides accurate measurements and preserves distances and angles relatively well within each zone.

    When correcting magnetic north to grid north, what do we do with an easterly declination?

    • A.

      Divide by longitude

    • B.

      Add to magnetic north

    • C.

      Multiply by grid north

    • D.

      Subtract from magnetic north

    Correct Answer
    B. Add to magnetic north
    Explanation
    When correcting magnetic north to grid north, if there is an easterly declination, we need to add it to the magnetic north. This adjustment is necessary because magnetic north and grid north are not aligned and may have a difference known as declination. By adding the easterly declination to the magnetic north, we can obtain the correct grid north direction.

    Correct Answer
    B. Latitude and departure
    Explanation
    To calculate the misclosure in a traverse, we need to total the values in the columns for latitude and departure. Latitude represents the north-south direction, while departure represents the east-west direction. By summing up the differences between the observed and calculated values in these columns, we can determine the misclosure, which indicates the error or discrepancy in the traverse measurements. The other options (angle and distance, latitude and longitude, northings and eastings) are not relevant for calculating the misclosure in a traverse.

    Explanation
    The proportion of horizontal distance is used to determine the misclosure in the latitude or departure. This means that the difference between the measured and calculated distances in the horizontal direction is taken into account when calculating the misclosure. By comparing the actual horizontal distance with the calculated distance, any errors or discrepancies can be identified and quantified. This allows for a more accurate determination of the misclosure in the latitude or departure.

    How many seconds do we set our post-processed kinematic (PPK) observation times to in order to ensure sub-centimeter accuracy?

    • A.

      15

    • B.

      30

    • C.

      45

    • D.

      60

    Correct Answer
    B. 30
    Explanation
    To ensure sub-centimeter accuracy in post-processed kinematic (PPK) observation times, we set the observation times to 30 seconds. This duration allows for a sufficient amount of data to be collected and processed, resulting in more precise measurements. A longer observation time may not significantly improve accuracy, while a shorter duration may not provide enough data for accurate calculations. Therefore, setting the PPK observation times to 30 seconds strikes a balance between accuracy and efficiency.
