A Hydrology Metadata Visualization Method Based on XML Schema

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.
