Urban safety risk spatial data fusion processing and visualization method

Abstract

The present disclosure relates to the technical field of data analysis and application, in particular to an urban safety risk spatial data fusion processing and visualization method. According to the urban security risk spatial data fusion processing, an SVG spatial data coding scheme is designed, an SVG spatial data management mode is provided, and an engine is developed and assembled to provide an SVG-based data source access mode for a user. According to the spatial data visualization method, data in an MDF format is written into a corresponding SVG document through a mode matching method, and map visualization of the SVG and GIS visualization of the SVG are achieved. According to the method, SVG is used as an organization form of spatial data, and formation of spatial information islands is avoided based on the characteristics of XML and application of Web.
