“Description of station” is the integration of data in topography using tables to record geological point positions. The users can easily get hand on relevant information and status of the point positions via the recorded contents of the description of station system. The system can assist the user to accurately and quickly arrive at the scene of the point to execute related topographical operations.
The description of station can mainly be applied to the triangulation points, wire points, leveling points and other measurement stakes. It can also be applied to other topographical projects such as significant boundary piles or right-of-way stakes. The contents of the description of station include the description, coordinates, grade, location, point position map, buried pile profile and other information.
The total length of TIAA MRT is 51.03 km. The right-of-way management problems seldom occur within the scope of the route sections. However, the stations are usually located in the urban development zone with high land use intensity. The relationship between the neighbors is very close, so the importance and sensitivity of right-of-way stakes is more significant.
A21 station is located in Zhongli district of Taoyuan City, beside Zhongfeng Road and close to private houses and private land. The definition of the scope and management of the station right-of-way needs to rely on the right-of-way stakes as important basis. If there is still controversy, boundary verification can be used to clarify the measurement by the Land Office. Therefore, the description of station production of right-of-way stakes acts as the first line of defense for right-of-way management.
The purpose of the production of description of station is to allow the management unit to correctly and quickly reach the site and find the boundary to carry out right-of-way management. Therefore, the contents of the record must be accurate and detailed, including the stake number, posts, coordinates, real photos, survey station sheet and stake location overview. The real photo must be able to show the topography and location of the stake; the survey station sheet must have at least two important clear topographies. The distance between each topography and the stake is measured so that the position of the right-of-way stake can be quickly located via the resection method when the stake is lost.
The description of station survey station sheet of A21 station was generated using the completion drawing as the base map. Due to the detailed facilities, equipment location and related terrain in the completion drawing, it can show the most of the station status as the base map for mapping. The results of mapping can accurately reflect the status of the right-of-way stake position; stake location recovery via the resection method when the stake is lost is also very accurate.
