Accuracy The degree of correctness of perfection obtained in the measurement
Precision Refers to the extent to which an instrument can measure
Accidental Errors Occur randomly and produce error in the measurement
Systematic Error Repetitive error that are caused by imperfections or malfunctions of the
surveying equipment
Meridian A horizontal reference line for measuring direction
True Meridian Is a imaginary line that passes through a point and the geospheric north and
south poles
Azimuth Clockwise Horizontal angle between the line and a given reference direction
or meridian
Bearing Bearing of a line is the horizontal acute angle between the meridian and the
line (or course)

Back bearing Same angle but reverse direction
Nadir Angle Downward vertical direction
Zenith Direction Upward Vertical Direction
Latitude Projection of a course of a traverse on the north-south axis of a rectangular
coordinate system
Departure Projection of a course of a traverse on the east-west axis of a rectangular
coordinate system
Latitude and Departure Can be used to determine the precision of a traverse by noting the plus/minus
closing of the _____________ & _______________
Sources of Errors Blunders, Systematic Error, and Accidental Error
Blunders A significant mistake caused by human error, caused by lack of attention or
carelessness, also called gross error

Coordinate System The results of a horizontal control survey are generally expressed by
rectangular coordinates
Back Azimuth Determined by adding (or subtracting) 180 degrees to the forward azimuth
Zenith Is the point on the celestial sphere vertically above a given point
Freeboard is elevating a building's lowest floor above predicted flood elevations by a
small additional height (generally 1-3 feet above National Flood Insurance
Program [NFIP] minimum height requirements)
What are benefits of Freeboard? 1) Increased protection from floods and storms
2) Better preparation for ongoing sea level rise
3) Greatly reduced flood insurance premiums
What occupations benefit from having Freeboard? 1) Homeowners
2) Builders/Contractors
3) Municipalities
4) Businesses
