Traverse is a method in the field of surveying to establish control networks. [1] It is also used in geodesy . Traverse networks involve placing survey stations along a line or path of travel, and then using the previously surveyed points as a base for observing the next point.
Compass surveying is a type of surveying in which the directions of surveying lines are determined with a magnetic compass, and the length of the surveying lines are measured with a tape or chain or laser range finder. [2] The compass is generally used to run a traverse line. The compass calculates bearings of lines with respect to magnetic needle.
The initial survey operations are concentrated on locating monuments. Property corners may be marked by iron pins, metal survey markers, iron pipes, and other features possibly establishing a line of possession will be located. When the approximate positions for the boundaries of the property have been located, a traverse is run around the ...
A survey using traverse and offset measurements to record the location of the shoreline shown in blue. Black dashed lines are traverse measurements between reference points (black circles). The red lines are offsets measured at right angles to the traverse lines. Few survey positions are derived from the first principles.
Position resection and intersection are methods for determining an unknown geographic position (position finding) by measuring angles with respect to known positions.In resection, the one point with unknown coordinates is occupied and sightings are taken to the known points; in intersection, the two points with known coordinates are occupied and sightings are taken to the unknown point.
The Transcontinental Traverse (TCT) was a geodetic survey traverse conducted in the continental United States by the United States Coast and Geodetic Survey between 1961 and 1970 and the U.S. National Geodetic Survey between 1970 and 1976. It was the most accurate large-area survey ever done prior to Global Positioning System surveys.
Total stations are the primary survey instrument used in mining surveying. A total station is used to record the absolute location of the tunnel walls, ceilings (backs), and floors, as the drifts of an underground mine are driven. The recorded data are then downloaded into a CAD program and compared to the designed layout of the tunnel.
In surveying, free stationing (also known as resection) is a method of determining a location of one unknown point in relation to known points. [1] There is a zero point of reference called a total station. The instrument can be freely positioned so that all survey points are at a suitable sight from the instrument.
