Embodiment

[0041] This solution is applied to deal with the relationship between point, line, and area elements and the problems of point duplication, line duplication, line partial inclusion, and line mutual inclusion in the iterative storage process of local data and database data. The process is as follows: figure 1 shown.

[0042] The specific description is as follows:

[0043] (1) Load the surface graphic data that needs to be stored.

[0044] (2) Calculate the envelope range of the loaded surface data, the calculation formula is as follows:

[0045] x min =Min(Min({X|X=X mn ,m∈N *,n∈N *}))-ε Equation 1

[0046] x max =Max(Max({X|X=X mn ,m∈N * ,n∈N *}))+ε Formula 2

[0047] Y min =Min(Min({Y|Y=Y mn ,m∈N * ,n∈N *}))-ε Equation 3

[0048] Y max =Max(Max({Y|Y=Y mn ,m∈N * ,n∈N *}))+ε Formula 4

[0049] Where: X min 、X max are the minimum and maximum values ​​of the enveloping rectangle in the X direction, and Y min , Y max is the minimum and maximum value in th...

Abstract

The invention belongs to the field of geographic information, and relates to an edge matching warehousing method, in particular to an edge matching warehousing method for basic geographic data. The method includes the steps that the enveloping range of surface graphic data to be warehoused is calculated; warehoused data meeting the condition that the warehoused data and the enveloping range have an intersection set is screened out of a database; the topological relations between the screened-out warehoused data and the surface graphic data to be warehoused are checked, and the surface graphic data to be warehoused and the warehoused data with the topological relations having problems are modified and saved. Thus, the method has the advantages that various spatial topological relations between authentic right spatial data to be warehoused and authentic right spatial data in the database can be visually and transparently reflected, the topological problems of edge sharing, overlapping, intersection and inclusion in the authentic right spatial data can be rapidly handled, conflict between the authentic right spatial data to be warehoused and the authentic right spatial data in the database is avoided, and the correctness of the authentic right spatial data is guaranteed.

Description

technical field [0001] The invention relates to a border storage method, belonging to the field of geographic information, in particular to a border storage method for basic geographic data. Background technique [0002] At present, in the confirmation and registration business of rural land contractual management rights, the storage of spatial data for confirmation of rights mainly includes the storage of contracted plots, boundary points, and boundary lines. Since what needs to be established is a county-level unified title confirmation database, the number of contracted land in a county can reach more than 1 million, the number of boundary lines can reach more than 10 million, and the number of boundary points can reach more than 10 million. What's more, adopting a one-time storage of the right-confirmed spatial data firstly does not conform to the actual operation mode, and secondly, the efficiency will be very low, so the method of batch storage is generally adopted. ...
