Surveying

Public land survey system (PLSS) typically divides land into _

6 mile square townships

How close your answer is to the exact answer

Accuracy

PLSS also divides land into one-mile square sections. The area of a section is: One square mile 640 acres Four quarter sections All of the above

All of the above

When surveying, angles can be measured by distances using: Tape Trig trilateration all of the above

All of the above

_ direction angles are measured in the clockwise direction from north

Azimuth

In surveying leveling procedure a _ is a differential elevation of a point BEHIND the INSTRUMENT

Backsight

N 86° 59' 59'' E is an example of a _ direction angle

Bearing

A bearing is a direction measured clockwise from north

False

All engineer levels measures horizontal distances

False

Geodetic surveying assumes that the surveyed surface is projected onto a rectangular mathematical surface

False

True north is the point on the earth where the north pole of the earth's natural magnetic field is located

False

Which of the following are primary cardinal directions? North South East West Azimuth Bearing

North, South

The way to correct mistakes in surveying field note and level book entries is to _

Strike through

A plat is a plan, map, or chart of a piece of land with actual or proposed features included on it.

True

An error is any difference between true value and measured value. A mistake is one type of error cause by human blunders.

True

Azimuth directions do not include quadrant reference ie N 59 E

True

In the US surveying is a profession regulated in every state by a governing board

True

Precision is a measurement of repeatability. If the equipment has certain errors associated with a particular measurement, that measurement will not be accurate but easily may be repeatable.

True

Topographic surveys collect 3D info. They show the curvatures of the land i.e. valleys, riverbeds, mountains

True

In surveying, what is north: True Grid Magnetic A star isogonic declination

True, grid, magnetic

A _ is an intermediate point in a leveling procedure with a calculated elevation

Turning Point

Magnetic declination _ is the angle between true north and magnetic north varies with both longitude and latitude drifts all of the above

all of the above

The two basic categories of surveying are _ and _

boundary, engineering

In surveying, elevations are always referenced to some kind of _

datum

Boundary surveying locates _ or man-made changes such as buildings, fences, and roads

improvements

Surveying is a learned, licensed, self-policing profession dealing primarily with _ measurement and _ law

land

NCEES is a national nonprofit organization dedicated to advancing professional _ for engineers and surveyors

licensure

Meridians of _ converge at the poles and determine East-West position

longitude

What is the core of the science of surveying

mathematics

Electronic distance measurement uses _ of infrared light to measure distances

phase-shifting

Horizontal distances are always determined so that all measurements are on the same _

plane

Plane surveying assumes all horizontal measurements are taken on a single _ and all vertical measurements are relative to that _, thereby allowing for all calculations to be done using _ trigonometry

plane

Surveying is a _ regulated in every state by a _ board

profession, governing

Geodetic surveying assumes that the surveyed surface is projected onto a "_" mathematical surface

spheroidal

Any line passing through one and only one point on the circle is a _

tangent

7 types of surveying

topographic, hydrographic, route, property, final, aerial, and construction

Plane surveying assumes a fixed _ datum as part of _ coordinates in 3D space

vertical, cartesian
