Embodiment Construction

[0019] The mapping process of thematic maps is divided into four stages: data preparation and analysis, compilation of geographic base maps, production of thematic data, and graphic output. Each technical scheme is described respectively below.

[0020] 1. Distributed data extraction engine technology:

[0021] In the data preparation stage, the key point is how to extract key data from massive data. The processing of spatial data in this stage mainly includes data collection, data extraction, data synthesis, data transformation, etc., and finally forms a geographic thematic map with specific meaning. The distributed extraction technology is adopted for the massive data extraction scheme, and the system efficiency can be significantly improved by using simple factors for load balancing. For the situation where the servers have different computing capabilities but the communication parameters are the same, an asynchronous load balancing iterative algorithm is used. On this bas...

Abstract

The invention discloses an intelligent data extraction and thematic map generation engine based on the geographic information technology. The intelligent data extraction and thematic map generation engine based on the geographic information technology comprises a data access module, a data extraction module, a thematic data making module and a map presentation module, wherein the data access module extracts relevant data needed for making a thematic map from the data access module, the thematic data making module completes the making of the thematic map, and the map presentation module presents the made thematic map in a visualized manner. The intelligent data extraction and thematic map generation engine based on the geographic information technology has the advantages that since a distributed data extraction engine is adopted for data extraction and cache preprocessing of data sources, the system efficiency can be obviously improved aiming at mass data; since multidimensional analysis is conducted to the data by means of combining multiple analysis methods and overlay analysis and representation are conducted to the thematic map, the diversification of the presentation of the thematic map is realized.

Description

technical field [0001] The invention relates to the fields of big data analysis, extraction, and visual display, and the field of generating geographic information thematic maps based on massive data. It can also be applied to a wide range of public business data analysis and display fields related to the Internet and geographic information, to achieve rapid generation of thematic maps of geographic information. Background technique [0002] Geographic Information System (GIS) is an emerging technology developed with the development of geographic science, computer technology, remote sensing technology and information science. It is a computer information system capable of collecting, managing, analyzing and visualizing spatially related data. system. With the popularity of computer technology and the Internet, GIS applications have penetrated into various fields of social and economic production. At present, geographic information systems have been successfully used in reso...
