摘要
本文基于目前迅速发展的WebGIS技术,结合地理信息行业应用的特点,分析了目前最为流行的轻量WebGIS模式,提出了基于动态数据交换的专题制图自动化方法。该方法能够自动实现轻量WebGIS环境下各种复杂专题制图应用。利用该技术方法在环境监测网上实现了空气质量日报以及水质监测周报的动态专题地图发布;通过与其他基本应用模式的比较,得出了基于动态数据交换的自动制图功能扩展更灵活,更能满足行业用户特殊需求的结论,解决了轻量WebGIS环境下专题制图自动化实际应用问题。
This paper analyzed the lightweight WebGIS technology based on the rapid development of WebGIS and the character- istics of geography infornlation industry, and gave out the automatic method of theme cartography based on dynamic data exchange. With this method, the paper made the application of complex theme cartography in the lightweight WebGIS circumstance and realized air quality daily report and water quality monitor weekly report automatically. By comparing with other application patterns, the automatic cartography based on dynamic data exchange was concluded more flexible and could satisfy the special needs of clients. And this method resolved the problem of automatization of theme cartography in lightweight circumstance.
