Problems solved by technology

[0004] The existing processing and analysis of population data still lacks a visualization system specifically for the spatial visualization of demographic information and query analysis results. It is still unable to explain the internal relationship of the differences in population spatial distribution, and cannot reveal the similarities between populations in different regions. sex

Embodiment Construction

[0061]The present invention will be described in more detail below in conjunction with the accompanying drawings, so as to further understand the purpose, scheme and effect of the present invention.

[0062] The spatial visualization system of demographic information of the present invention emphasizes the management and analysis of both map spatial data and demographic data, and associates demographic data with spatial data, based on quantitative and structural features on map graphics. To draw the statistical symbols of population themes and realize the spatial visualization of population distribution.

[0063] figure 1 Describing the structural framework of the spatial visualization system for demographic information of the present invention, reference figure 1 , the spatial visualization system of demographic information includes: a database 10 for storing population attribute data and basic population spatial data for each functional module to obtain required data; a dem...

Abstract

The invention discloses a spatial visualization system of statistical population information and a method thereof. The spatial visualization system comprises: a database which is used for storing population attribute data and basic spatial population data for various functional modules to obtain the required population attribute data and basic spatial population data; a statistical population datamanagement module which is used for obtaining basic conditions of the population attribute data and managing the population attribute data; a spatial population data management module which is used for obtaining the basic spatial population data and providing an electronic map data platform based on the basic spatial population data so as to manage the basic spatial population data; and a statistical population and spatial data combination module which is used for correlating the population attribute data with the spatial population data, and converting the statistical population data into avisualized map image based on preset thematic symbols. The system and the method have the advantages of spatialization statistics and expression of population information, thus vividly expressing regional difference and distribution characteristics of population.

Description

technical field [0001] The invention belongs to the fields of population statistics, geographic information science and maps, and in particular relates to an electronic map visualization system for representing the spatial statistical distribution of population information. Background technique [0002] Since the founding of the People's Republic of China, my country has carried out five censuses successively, especially the fifth national census in 2000, which reached an unprecedented level in terms of content, scale, quality and technical level, and obtained a very rich population. National information. How to summarize and express the results of my country's fifth census, the in-depth development and application of these information is particularly important. [0003] Spatial visualization can provide a graphical interface to help users understand complex data sets. Spatial visualization usually refers to showing the distribution of data in geographical space, and can int...
