Traverse survey - Traverse survey

Also known as polygonal surveying. A method of surveying in which a series of broken lines connects points with known locations and unknown points, and starting from the known points, the distance and direction angle are measured for each broken line, determining the positions of the unknown points one after the other. Although the accuracy is inferior to triangulation, it can be done with visibility in one direction, so it is used in forested areas, urban areas, railways, etc. → Related topics Navigation tables | Plane surveying Source : Heibonsha Encyclopedia About MyPedia Information |

多角測量とも。位置のわかっている点と未知の点を一続きの折線で連ね，既知の点から出発して，一つの折線ごとに距離と方向角を測定し，次々と位置を決定して未知の点を測定する測量法。精度は三角測量に劣るが，１方向の視通があれば測量できるので，森林地帯，市街地，鉄道などで用いられる。 →関連項目航海表｜平板測量 出典 株式会社平凡社百科事典マイペディアについて 情報 |
