CDC 3E551 Engineering Journeyman Volume 1

Flashcards based on the lecture notes for the CDC 3E551 Engineering Journeyman Volume 1, focusing on key vocabulary and definitions relevant to surveying and engineering concepts.

Survey Theory

The principles that relate to the way surveying is practiced, including mathematical concepts applied to gather information.

Datum

A common reference surface used to relate survey points and lines accurately.

Geographic Coordinate System

A system that uses latitude and longitude to define locations on the Earth's surface.

Universal Transverse Mercator (UTM)

A conformal projection system used to represent the Earth's surface as a two-dimensional map.

Azimuth

An angle measurement based on a north line, used in surveying to define direction.

Canopy Jettison Explosives

Explosives located in ejection seats of aircraft, considered hazardous during mishap investigations.

Collimation Check

A procedure to determine if a total station's sighting is correctly aligned.

Weighted Airman Promotion System (WAPS)

A system used by the Air Force to evaluate and rank airmen for promotion.

Feature Code Libraries

Collections of codes that help surveyors quickly identify and classify survey data.

Pace Count

An estimating method of distance measurement based on the number of steps taken over a known distance.

Stadia Distance

A method of measurement using stadia lines on telescopes to determine distances.

Field Notes

A complete record of all measurements and observations made during a survey, crucial for legal verification.

Error in Surveying

The difference between the measured value and the true value, important for validating survey precision.

Misclosure

The total deviation from a closed traverse that needs to be adjusted to correct surveys.

Ionospheric Effects

Variations in satellite signal transmission caused by the ionosphere that can affect positioning accuracy.

Slope Stake

Stakes set to indicate where the ground meets the proposed grade for construction projects.

Topographic Survey

A survey that provides detailed information about the terrain, including contours and features.
