Traverse is a method in the field of surveying to establish control networks. 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. Traverse networks have many advantages, including: * Less reconnaissance and organization needed; * While in other systems, which may require the survey to be performed along a rigid polygon shape, the traverse can change to any shape and thus can accommodate a great deal of different terrains; * Only a few observations need to be taken at each station, whereas in other survey networks a great deal of angular and linear observations need to be made and considered; * Traverse networks are free of the strength of figure considerations that happen in triangular systems; * Scale error does not add up as the traverse is performed. Azimuth swing errors can also be reduced by increasing the distance between stations. The traverse is more accurate than triangulateration〔Chrzanowski and Konecny, (1965); Adler and Schmutter (1971).〕 (a combined function of the triangulation and trilateration practice).〔Schofield, Wilfred (2001). ''Engineering Surveying.''Butterworth-Heinemann. ISBN 978-0-7506-4987-2.〕 ==Types== Frequently in surveying engineering and geodetic science, control points (CP) are setting/observing distance and direction (bearings, angles, azimuths, and elevation). The CP throughout the control network may consist of monuments, benchmarks, vertical control, etc. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Traverse (surveying)」の詳細全文を読む スポンサード リンク
