Description

Centering device is used in cadastral survey and drawing

Technical Field

The utility model relates to a cadastral survey and drawing technical field specifically is a centering device is used in cadastral survey and drawing.

Background

The cadastral surveying and mapping mainly comprises cadastral control measurement, boundary point measurement and cadastral map surveying and mapping. The technique and method are substantially the same as in control surveying and topographical mapping in engineering metrology. The cadastral control measurement follows the principle of distribution from high level to low level from whole to local, and can be divided into basic control measurement and encryption control measurement. The cadastral control network is established in the same way as the engineering control network, and may be established by conventional ground measuring method, satellite positioning method and comprehensive satellite and ground measuring method. The land area calculation in cadastral survey is a multi-level horizontal area measurement. For example: total area of an administrative jurisdiction, map area, neighborhood area, parcel area, various utilization classification areas, and a summary of land areas, etc. The land area calculation method has two methods, namely an analytic method and a graphical method. The analytic method is a method for calculating the area according to the actually measured value, and is mainly a coordinate method, namely, the area of the land parcel is calculated according to the coordinate of the inflection point of the boundary of the land parcel. The coordinates can be directly measured in the field or graphically obtained from an existing map, and the accuracy of the area depends on the accuracy of the coordinates. When the land is irregular, even some sections are curves, inflection points can be added to measure the coordinates. The more encrypted points on the curve, the closer to the curve, and the closer the calculated area is to the actual area.

At present, the cadastral centering device for survey and drawing that uses, when carrying out the centering setting, hardly make level for the mount pad with the centering rod, the centering rod counter weight thing is most as an organic whole with cadastral survey and drawing tripod moreover, is not convenient for assemble and dismantle the counter weight thing, leads to carrying inconveniently.
