Intelligent output method for land parcel maps

Abstract

The invention discloses an intelligent output method for land parcel maps based on GIS technology. The method can realize intelligent output printing of the land parcel maps adaptive to the national conditions of China by automatically extracting required information from a standard cadastre database. The method appoints a map scale or appoints the size of paper according to the user requirement to carry out map printing output; a user only needs to input an identification code of a land parcel such as a land parcel number or a cadastre number; and the method automatically acquires the land parcel maps, and determines the size and scale of the proper paper by calculating related map attributes. According to the land parcel maps, a map output mask is calculated so as to determine the visual range of the land parcel maps. The method also uses a label optimizing configuration algorithm so as to solve the gland problem of boundary point number labeling text elements. The method simulates the reasoning mode and thinking process during drawing, realizes intellectualization of land parcel map output, effectively reduces the workload during drawing the land parcel maps, and has large application prospect in the cadastral management field and other related drawing fields.

Description

technical field [0001] The invention relates to the field of cadastre management mapping, in particular to an intelligent output method of parcel maps based on GIS (Geographic Information System) technology. It also has a certain reference value for other related land industry mapping fields, and this method has practical significance for the office automation of the land department. Background technique [0002] The land parcel map is the attached map of the land certificate. After the approval of the land registration process with legal procedures, it is a legally effective map certificate held by the land owner or user, and it is a legally effective map when dealing with land ownership issues. pieces. [0003] The main contents of the parcel map include: map frame number, cadastral number; the parcel number, land category number, area and unit name; the boundary point and boundary point number of the parcel (including the boundary point shared with neighboring parcels) ...

AI Technical Summary

Problems solved by technology

[0005] The deficiencies in the current parcel map mapping output process are as follows: (1) During the parcel map mapping output process, the paper size needs to be manually judged by the operator

(2) The content of the map lacks screening; it can be seen from the content of the map that in order to reduce the load on the map, it is not necessary to display its entire graphic or all boundary lines on the map of the neighboring block It is only necessary to display the boundary line adjacent to this case, and it is difficult to achieve the desired effect through the manual operation of the operator, and the computer must be used to automatically and accurately screen the content

(3) Operators need to manually add and edit a large number of annotations

Manually modifying the size, position and color of annotation fonts in the parcel map will inevitably bring a lot of work to the operators
