Surveying Final (12-9-21) Flashcards
Provides line, lean, control elevation, horizontal position, dimensions, and configurations for construction operations.
Construction Survey
Are made to plan, design, and construct highways, railroads, pipelines, or other linear projects.
Route Survey
Defines shorelines and depths of lakes, streams, oceans, reservoirs, or other bodies of water.
Hydrographic Survey
Has been as the science, art, and technology of determining relative positions of points above, on, or beneath the earth’s surface or establishing such points.
Surveying
The point about which a line rotates to form an angle.
Vertex
Established a network of horizontal and vertical monuments used as a reference framework for other surveys.
Control Survey
What are permanent reference points that are marked to be used in the future?
Monuments
The last foot of this tape is marked in tenths and inches and requires mental subtraction.
Cut Tape
The amount of two dimensional space encompassed within the boundary of a closed figure or shape.
Area
Consists of a magnetized steel needle mounted on a pivot at the center of a graduated circle.
Compass
Defined as a system of hardware, software, and data in organizational structure for collecting, storing, manipulating, and spatially analyzing geo-reference data.
GIS
Surveying the curved surface of the Earth. They are employed to determine the relative positions of widely spaced monuments. Based on sphere.
Geodetic Surveying
The reference base for field work and computations is assumed to be a flat, horizontal surface.
Plane Surveying
One end of the axis on which the Earth turns.
True North
The line of zero declination.
Agonic Line
Is used to mark the end of a tape or an intermediate point.
Chain Pin
How many minutes are in a degree?
60
Define Blunder
A significant mistake due to human error.
Define Natural Error
Caused by variation in wind, temperature, humidity, atmospheric pressure, refraction, gravity, and magnetic declination.
Define Instrumental Error
Result from imperfections in equipment.
Describe the difference between systematic errors and accidental error.
Accidental errors are usually small, random, and avoidable, while systematics errors are repetitive and constant(caused by errors in the surveying equipment).
