基于XML Web服务的地图增量更新模型研究

Research on cartographic incremental updating model based on XML Web service

从地图表达数据可持续利用的角度,提出基于XML Web服务的地图增量更新模型。分析基于Web服务的地图增量更新的原理、关键技术以及实现过程,并结合GML、XSLT表达规则、SVG地图符号及JavaScript设计,实现基于XML的地图表达数据增量更新的原型系统。

The paper puts forward a cartographic incremental updating model based on XML web service from the perspective of sustainable utilization of cartographic representation data,and analyses the principle,gordian technique and implementation process of cartographic incremental updating model based on Web Service,and develops an incremental updating prototype system of cartographic representation data based on XML by using GML,XSLT representation rules,SVG map symbol and JavaScript.
