摘要
数据交换是海域资源信息数据库建设的重要内容,不同系统之间的数据互访,成为近年来GIS应用系统开发中需要解决的问题。文章分析了当前GIS数据格式转换的基本方式,比较了各转换方式的优缺点,在此基础上结合组件技术的重用性、灵活性、扩展性等特点,阐述了利用嵌入式组件开发技术进行GIS数据转换的思路与方法,并结合确权海域数据实例给出了实现的具体步骤。结果表明该转换方法速度快、可靠性强、数据准确度高,达到了GIS数据格式转换的完整性和精度要求。
Data exchange is the main content in information database construction of maritime space,and problem of data sharing between software systems is becoming the important question that needs to be resolved in developing of application systems of recent years.It analyzed the present basic modes of GIS data conversion,compared the merits and drawbacks with each other and from which combining with reusability,flexibility and extendibility of com technology,discussed the thought and method of GIS data conversion based on embedded com technology,and displayed the procedure with data sample.The result showed that this method was high speed,strong reliability,high accuracy and reached the integrality and precision demand of GIS data conversion.
