Method for drawing administrative map of HTML5 rich client side

Abstract

The invention provides a method for drawing an administrative map of an HTML5 rich client side. The method is as follows: on the basis of a hierarchical simplified storage strategy, the compression transmission problem of an administrative division coordinate data internet is solved; the client-side coordinate drawing number is greatly reduced; on the basis of service-oriented thoughts, real-time fusion of multiple sources, multiple scales, multiple service data and spatial data is solved; and the dynamic colour matching problem at the client side in the more than 3000 nationwide administrative divisions (comprising province, municipality and county levels) is solved by utilizing a four-colour image colouring template. On the basis of a customized education geographical information system successfully researched and developed by the invention, integration is achieved in multiple service systems in a gold teaching engineering; dynamic, templated and customized statistical drawing of multiple administrative-level service data of different sources can be realized; and the system is popularized and applied in 32 nationwide provinces in 2015.
