Water conservancy general survey data result dynamic thematic map generating system and method

Abstract

The invention discloses a water conservancy general survey data result dynamic thematic map generating system and method. The system comprises a data persistent layer, an asynchronous refresh display controller, a GIS thematic map drawing module, a general survey data warehouse unit, an encapsulation map service object and a user interface. The method includes the steps that a user sends a request to the asynchronous refresh display controller, the asynchronous refresh display controller calls the data persistent layer to extract dimension information and classification information data from the general survey data warehouse unit, the data are connected and returned, and dimensions in a dimension selective area and classification information of the dimensions are refreshed; the asynchronous refresh display controller obtains a data manipulation command and obtains a thematic map visual effect command customized by a user according to a thematic map effect customization area and a thematic map type selective area; according to data returned by the general survey data warehouse unit, the data are connected to form a complete format to be transmitted into the GIS thematic map drawing module and a data ranking module; the GIS thematic map drawing module calls the encapsulation map service object to form a thematic map and refreshes a thematic display area and a data ranking area.

Description

[0001] technical field [0002] The invention relates to a method for generating a dynamic thematic map of data results, in particular to a system and method for displaying a data thematic map adapted to a data warehouse of a water conservancy census. Background technique [0003] The first national water conservancy census carried out from 2010 to 2012 is a major national condition and national strength survey and an important part of the national resources and environment survey. The first national water conservancy census included basic surveys of rivers and lakes, basic surveys of water conservancy projects, economic and social water use surveys, general surveys of river and lake development, management and protection, water and soil conservation, general surveys of water conservancy industry capacity building, and irrigation districts and groundwater intake Well two special censuses. Since the census of water conservancy has designed more than 300 statistical indicator...

AI Technical Summary

Problems solved by technology

[0004] In the current census data visualization methods, traditional tables and charts have been difficult to meet the needs of professionals for data analysis

At the same time, the census data has a common spatial data inline, and the existing water conservancy census data is not integrated with GIS (Geographic Information System)

Census data has great research value for professional analysis, but there is a lack of an intelligent platform system to complete the integration of data warehouse and GIS, and it is impossible to display and analyze data intuitively and orderly in the form of GIS thematic maps
