Alternating type online statistical map generation and releasing device and method thereof

Abstract

The invention discloses an alternating type online statistical map generation and releasing device and a method thereof; the device comprises a statistical composite element resource generation module, a statistical graphic processing module and a statistical map release processing module, wherein the statistical composite element resource generation module is used for generating a statistical element resource library according to input statistical attribute data and statistical unit base spatial data; the statistical graphic processing module carries out hierarchical layer description and statistical layer description respectively according to data input by the statistical element resource library, a set thematic statistical symbol script library and a color scheme library and is combined with a base map layer resource library and uses a layer resource ID as an identifier to carry out combined processing so as to generate the statistical map resource library; and the statistical map release processing module is used for providing a user requirement customization input interface and generating and outputting statistical map data customized by a user according to data input by the user requirement customization input interface.

Description

technical field [0001] The invention belongs to the technical field of geographic information statistics, and in particular relates to an Internet-based interactive statistical map generation and distribution device and method. Background technique [0002] With the further popularization and application of computer network technology and the continuous penetration of computer Internet into people's production and life, the traditional data publishing, sharing and application modes have undergone great changes. [0003] For the statistical industry, the statistical agency regularly publishes the national industry statistics by province, prefecture, county, and even township by administrative division and industry statistics by regional geographic characteristics through printing and publishing, CD-ROMs, and network downloads. . Based on the analysis of current web services, distributed computing and other related technologies and software architecture models, it is found th...

AI Technical Summary

Problems solved by technology

Based on the analysis of current web services, distributed computing and other related technologies and software architecture models, it is found that current users have the following problems in the acquisition and application of statistical data: First, the published data is generally carried out through two-dimensional tables or single statistical charts However, the chart method cannot reveal the spatial characteristics of the statistical units very well. Therefore, the spatialized statistics and expression of industry statistical data, and the visual expression of the regional differences and distribution characteristics of the data are important to improve the spatial cognition level of the industry. It is extremely important; the second is that the way of data release is relatively backward. With the development of web technology and the rise of network services such as wms / wfs and kml, the release of statistical data should be able to integrate with these services and trigger more statistical data application growth The third is that when statistical data is applied, it is generally necessary to combine gis software and statistical software for in-depth processing, and the software cost is relatively high. Therefore, it provides an online statistical information spatial visualization system and builds user-interactive spatial cognition visualization. environment is very important

However, the relevant patents listed above only involve a separate map release system, and none of them can realize user-interactive map generation and release technology.
