Embodiment Construction

[0047] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0048] At present, the existing gridded statistical methods cannot satisfy high precision and high computing efficiency at the same time. Based on this, a spatial data gridded statistical method and device provided by the embodiment of the present invention can be based on the traditional gridded statistical analysis On the premise of ensuring the statistical efficiency of gridding, ...

Abstract

The invention provides a spatial data gridding statistical method and a spatial data gridding statistical device, which relate to the technical field of geographic information and comprise the following steps of: selecting a to-be-counted target hierarchy in a candidate hierarchy set; Carrying out gridding calculation on a target statistical range by utilizing a preset grid coding system to obtaina grid code and a broken net mark proportion of each space vector element in the target statistical range in the target hierarchy; Determining the total standard grid number according to the grid codes of the plurality of space vector elements and the broken net mark proportion; And determining an area statistical result of the target statistical range according to the total standard grid numberand the standard grid area. The invention provides a spatial data gridding statistics method and device, on the basis of traditional gridding statistics analysis, the grid code and broken net mark proportion of each spatial vector element in a target statistics range in a target level is calculated, and the statistics precision is improved on the premise that the gridding statistics efficiency isensured.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a gridded statistical method and device for spatial data. Background technique [0002] With the advent of the era of geographic information big data and the development of new fields of geographic monitoring in China, geographic information application services have gradually evolved from standardized map services to diversified decision-making analysis, bringing unprecedented new opportunities for statistical analysis and information mining of massive geospatial data. need. As an emerging statistical analysis method, spatial data gridded statistical analysis method realizes spatial position correlation and correlation analysis through a unique spatial position code, effectively reducing the complexity of statistical analysis of massive spatial data [0003] Gridded statistical analysis defines the traditional earth space with a multi-level subdivision grid, and ...
