Description

Cadastral surveying and mapping tripod

Technical Field

The utility model relates to a cadastral survey and drawing tripod.

Background

The cadastral surveying and mapping is a surveying and mapping work which accurately measures the coordinates of boundary points of the territory ownership boundary lines, accurately draws the positions, areas, ownership relations, utilization conditions and other elements of the territory and attachments thereof on a drawing and records the elements in a special book. The result of the cadastral survey includes a data set (control point and boundary point coordinates, etc.), a cadastral map and a cadastral book.

The cadastral survey is a professional survey serving the cadastral management, and is a survey and area calculation work performed to satisfy the needs of the cadastral elements such as the rights, position, shape, number, and the like of the land parcel in the cadastral management. One of the important results of cadastral survey is cadastral mapping, so that cadastral mapping plays a crucial role in cadastral survey and even cadastral management. The main contents of cadastral survey include cadastral survey, cadastral plane control survey, land boundary point determination, cadastral map drawing, land area calculation and the like.

Cadastral survey and drawing is mainly with the help of the instrument, and the instrument needs to support through the tripod, but we can discover when actually measuring, because the unevenness on ground leads to the unable effectual support plane that forms in top of tripod, consequently during survey and drawing, needs frequent regulation tripod put the stationarity to obtain accurate measured data, the operation is comparatively troublesome.
