跨平台自适应符号化技术研究

Research on cross-platform adaptive symbolizing technology

提出了一种跨越不同GIS平台的自适应符号化解决方案,将符号系统分为通用符号系统、符号接口和符号插件三部分。通用符号系统独立于具体GIS平台,负责处理平台无关的符号化功能;符号接口规定通用符号系统和具体GIS之间的交互接口;符号插件是符号驱动接口的具体实现,通过符号插件完成通用符号系统和具体GIS平台的集成。详细地研究了利用Javascript技术实现通用系统和符号插件的具体方法,并在国内外几个著名的GIS平台实现了符号插件,使符号能够在这些平台上共享与通用。

This paper proposed an adaptive cross-platform symbolize model for GIS, including the common symbol system, symbol driver interface and symbol plugin. It studied the implement method of the model by Javascript technique, and its feasibility has been validated by almost all of the well-known GIS software,internal and overseas. symbol ; Javascript; adaptive symbolizing technology
