Embodiment Construction
[0052] The following is further described in detail through specific implementation methods:
[0053] The embodiment is basically as attached figure 1 And attached figure 2 Shown: the method for automatically calculating other precise coordinate points based on known coordinate points is characterized in that it includes the following steps:
[0054] Coordinate system pre-storage steps: Pre-storage multiple coordinate systems, the coordinate systems include the Earth 2000 coordinate system, Xi’an 80 coordinate system, Beijing 54 coordinate system, WGS-84 coordinate system and the corresponding regional independent coordinate systems of each region. The regional independent coordinate systems are as follows: Chongqing independent coordinate system, Henan independent coordinate system, etc.
[0055] Coordinate point acquisition step: obtain known coordinate points, which are points obtained after being collected by surveying and mapping instruments. In this embodiment, the su...

The present invention relates to the technical field of surveying and mapping of natural resources and real estate, in particular to a method for automatically calculating other precise coordinate points based on known coordinate points, comprising the following steps: the step of obtaining coordinate points: obtaining known coordinate points; the step of obtaining spatial relations: obtaining already The spatial relationship between the known coordinate point and the target point to be calculated; the step of calculating the coordinates of the target point: according to the spatial relationship between the known coordinate point and the target point to be calculated, calculate the coordinates of the target point to be calculated, in this way to solve the problem caused by environmental reasons For the problem of inconvenient measurement when measuring the coordinate points of the target to be measured, the present invention is mainly used to investigate the scene and form a plane graphic result.
Description
technical field [0001] The invention relates to the technical field of natural resources and real estate surveying and mapping, in particular to a method for automatically calculating other precise coordinate points based on known coordinate points. Background technique [0002] Natural resources and immovable property refer to properties that are immovable according to their natural nature or legal provisions, such as forests, rivers, lakes, grasslands, land, houses, prospecting rights, mining rights and other land fixtures, land formations that have not been separated from the land, Other things that are attached to the land due to nature or manpower and cannot be separated. [0003] The characteristics of natural resources and real estate as natural objects include: immovability, also known as position fixity, that is, fixed geographical location; individuality, also known as uniqueness and uniqueness, including differences in location, degree of utilization, and differen...
