摘要
随着水利遥感技术的发展,水利行业的遥感影像数据越来越多。遥感影像具有文件容量大、人们无法直接读取其中信息等特点,因此在水利上需要为其构建相应的元数据增强可读性。元数据一般由XML文档存储,缺乏统一管理。为了使元数据管理者更好地掌握水利遥感影像信息,需要一种元数据可视化方法。使用一种基于XML Schema的元数据可视化方法,并利用XML Schema对界面数据直接验证。该方法可以较规范地描述元数据,达到可视化效果,并实现可视化与数据验证的集成。
With the rapid development of satellite remote sensing technology, there are more and more satellite remote sensing data on hydrology. Remote sensing data are usually massive and read only by machine. So we need metadata to get information from remote sensing data. Metadata are stored in XML file and it cannot be managed in the same method. By using a visualization method, we can learn the hydrology data easily. This paper proposes a metadata visualization method based on XML Schema and it can describe the metadata normally. Visualization and data validation can be integrated in this method.
