Study Notes
Surveying Methods
- Lines are first run around the perimeter of the plot, then details are fixed in relation to the established lines, a process called triangulation.
- Triangles are preferred in surveying as they can completely cover an irregularly shaped area with minimum space left.
Traverse Survey
- Traverse survey involves establishing the position of a point on the ground using the bearing and distance of a known point.
- From this point, the bearing and distances of other surrounding points can be established, creating a network of connected lines.
Types of Traverses
Closed Traverse
- A closed traverse involves a series of connected lines that form a closed circuit, where the finishing point coincides with the starting point of a survey.
- Suitable for surveying boundaries of ponds, forests, etc.
Open Traverse
- An open traverse involves a sequence of connected lines that extend in a general direction and do not return to the starting point.
- Suitable for surveying areas where a return to the starting point is not necessary.
Classification of Surveys
By Purpose
- Engineering survey
- Control survey: uses geodetic methods to establish widely spaced vertical and horizontal control points
- Geological survey: determines the structure and arrangement of rock strata
- Military or Defense Survey: maps places of military and strategic importance
- Archeological survey: discovers and maps ancient relics of antiquity
By Instrument Used
- Chain/Tape Survey: uses a chain or tape for linear measurements with no angular measurements
- Compass Survey: uses a magnetic compass for horizontal angular measurements with linear measurements
- Plane table survey: quick survey carried out in the field with simultaneous measurements and drawings
- Leveling: measures and maps relative heights of points on the earth's surface
- Theodolite Survey: takes vertical and horizontal angles to establish controls
