Abstract

This paper discusses how to display the map of the major hazard information system using SVG technology.This system makes use ofthe SVG's advantages of describing the vector graphics.A descriptive model of map symbol based on SVG is presented.It describes the generalpoints, lines and regions, depending on which, most of the entity objects in map are displayed.The storing method of space data in digital map isimplemented by using the characteristics of SVG based on XML.This method sets up an efficient relationship between the space data and theattribute data.
