Abstract

The invention discloses a map visualization system and method for knowledge mining based on spatial big data. The method comprises the following steps: drawing a visualization area space-time basic map: drawing the determined visualization area space-time basic map according to a GIS geographic information system; realizing a spatio-temporal data acquisition step: according to the geographic position information of the determined area range, acquiring spatio-temporal data with geographic attributes and time attributes in the area range based on a GIS geographic information system; realziing adata analyzing and processing step: analyzing and processing the obtained space-time data; and realzing a visualization model display step: inputting the output result of the data analysis processingstep and the space-time basic map into a visualization model to realize visualization display of the determined area map. The space-time basic map for determining the urban area and the collected space-time data are imported into the visual model to be processed, and finally visual display of the map is achieved through the space-time visual display terminal, so that map representation is more visual.

Description

technical field [0001] The invention relates to the field of geographic information visualization, in particular to a map visualization system and method for knowledge mining based on spatial big data. Background technique [0002] Geospatial information is an important national information resource. With the development and progress of science and technology, it is urgent to realize the comprehensive utilization and online services of national multi-scale and multi-type geospatial information resources; in the era of big data, the construction of smart cities requires spatio-temporal big data for In the process of building a smart city, the knowledge mining and the visualization of its map are a major manifestation of a smart city; however, there is currently no way to visualize a smart city map. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a map visualization system and method for kn...
