Angles
What is an azimuth?
A horizontal angle measured clockwise from the reference median.
What does COGO stand for?
What does QC stand for?
What is "quality control"?
Give an example of a closed traverse.
Property boundaries/lines
Area for quantities
Control Survey
What is a bearing?
The acute horizontal angle between a reference median and line.
What is the error between magnetic north and true north called?
What does QA stand for?
What is "quality assurance"?
Give an example of a survey technology
GPS
Total Station
Drone
Auto Level
Data Collector
Feet
You are in the NW quadrant, how do you go from an azimuth to a bearing?
Subtract the azimuth from 360
What is angular misclosure dependent on? What is the formula?
The number of sides in a polygon.
(n-2)*180
Why do we need quality control?
Safety
Performance
Cost
Longevity
Etc.
Give an example of a pattern seen on a topographic map.
A ridge or valley will have a specific looping pattern. ((((
What would the bearing be of 62d44'12"
N62 44' 12"E
How can you use azimuths to find interior angles if both lines are in quadrant I?
Use the forward azimuth of your first line to find the back azimuth of your first line. Then, subtract the first azimuth of your second line from the back azimuth of your first line.
Give an example of quality assurance during your background research?
Standards
Codes
Design Methods
Give an example of an angle (in DMS) that would be in the southeast quadrant.
Angle between 90-180 degrees
You have <GAB and <ABT. If AZGA is 65, what is AZAG?
AZAG = 180 + AZGA
AZAG = 180 + 65
AZAG = 245
What is your latitude and departure? What coordinates do latitude effect? What about departure?
Latitude and departure are the straight distances between two points. Latitudes effect the N/S/y coordinates and departures effect E/W/x coordinates.
What should your interior angles add up to on a polygon with 13 sides?
(n-2)*180
(13-2)*180
11*180
1980 degrees
