method of surveying and mapping that uses a set of standard survey points as reference points for all subsequent surveys.

Control Surveying

method of surveying and mapping that uses a set of ___________ as reference points for all subsequent surveys.

standard survey points

method of surveying and mapping that uses a set of standard survey points as _________ or all subsequent surveys.

reference points

typically placed in locations that are easily identifiable

Control Points

determination of the precise position of a number of stations which are distributed over a large area.

Control Surveying

used to establish the horizontal position of points in a survey network and also used to measure distances and angles between points and to establish the relative positions of points in a plane.

Horizontal Control Survey

Three Types of Horizontal Control Survey

Control by Traversing, Control by Trilateration, Control by Triangulation

consist of closed polygons with most of the sides and angles measured directly in the field

Control by Traversing

series of horizontal distances and directions are observed to connect points whose positions are to be determined

Control by Traversing

_____ are measured more accurately than ______ .

distances, angles

consist of networks of geometric figures with almost all of the angles measured directly in the field and with relatively few of sides, measured.

Control by Triangulation

lengths of the sides of a series of triangles are measured and the angles from the lengths

Control by Trilateration

Mountainous and hilly: Flat, Open Terrain:

Triangulation, Traverse

used to measure the elevation of the points in the survey area.

Vertical Control Survey

3 Types of Veetical Control Survey

Barometric, Differential, Trigonometric

best run over level or gently sloping terrain.

Differential Leveling

used when transferring elevations from precise leveling circuits to selected triangulation stations.

Trigonometric Leveling

well suited for reconnaissance surveys where approximate elevations are required

Barometric Leveling

the surveys conducted covering extensive areas

Geodetic Control Survey

surveys conducted to establish the positions of points of reference for projects with a limited geographic coverage

Project Control Survey

Parts of Markings of Monuments

Provincial Code, Control Point Number, Year Established, Order of Accuracy, Office or entity that established the reference monument
