FE CIVIL EXAM questions and answers2024
Plane Surveys - Type of survey that disregards the curvature of the earth.
Appropriate if the area is small.
Geodetic Surveys - Type of survey that considers the curvature of the earth.
Zoned Surveys - Type of survey that allows computations to be performed as if on
a plane will accommodating larger areas.
State Plane Coordinate System - Rectangular systems that use a partial
latitude/longitude system for baseline references
Stadia Survey - Requires the use of a transit, theodolite, or engineer's level, as well
as a rod for reading elevation differences and a tape for measuring horizontal
distances
Plane Table Survey - Used in conjunction with a telescopic instrument. Used in
field compilation of maps and doesn't disturb the azimuth
Total Station Surveys - Integrates theodolites, electronic distancing measurement
(EDM), and data recorders

Triangulation - The positions of the survey points are determined by measuring
the angles of triangles defined by the points. Used primarily for geodetic surveys
Trilateration - Survey lines form triangles, but the lengths of the triangles sides are
measured
Photogrammetric Surveys - Conducted using aerial photographs
Airborne LIDAR (Light Detection and Ranging) - Aircraft mounted laser systems
designed to measure the 3D coordinates of a passive target
NAVSTAR GPS - Navigation Satellite Timing and Ranging Global Positioning System;
one-way satellite to receiver ranging systems. GPA determines position without
referencing any other point
Inertial Survey Systems - Determine a position on the earth by analyzing the
movement of a transport vehicle. Measures acceleration of the vehicle and
converts that to distance

Geographic Information System (GIS) - A computer system that stores, organizes,
analyzes, and displays geographic data. Contains spatial information, literal
information, and characteristics
Sexagesimal System - Degrees, minutes, seconds
60 minutes make up a degree, 60 seconds make up a minute
Positions - (a) latitude and logitude
(b) by rectangular (Cartesian) coordinates measured from a reference point
Benchmark - The common name given to permanent monuments of known
vertical positions
Control Stations (or Triangular Stations) - Monuments with known horizontal
positions.
Datum - Usually mean sea level, the point from where vertical elevations are
measured from

Gunter's Chain - standard unit of distance measurement, which equals 66 feet.
Cut Chains - 100' long tapes
Add Chains - 101' long tapes
Tachyometric Distance Measurement - Involved sighting through a small angle at a
distant scale
- Stadia method - angle fixed, length measured
- European method - length fixed, angle measured
Stadia Interval/Reading - Interval between two rod readings on a distant stadia
rod
Electronic Distance Measurement (EDM) - Very accurate for short (~2 mile)
distances and relatively accurate for longer distances
Stations - In route surveying, lengths are divided into 100' sections called stations
