The global warming is a worldwide topic. Severe weather like drought, tornadoes, and hurricanes is happening more often. Governments and corporations are investing heavily in climate related researches and data collections. As we know, geographic data is being collected and stored at an ever-increasing rate by government agencies, large corporations, small to medium companies, and individuals. It is a challenge to make those valuable data resources available to a wide range of data consumers. To make data easily discoverable, metadata standards have been established. With metadata, data can be easily indexed and cataloged into clearinghouses and online catalog systems. Data collecting and data producing organizations still face challenges to submitting their data for indexing due to missing metadata, invalid metadata, and incompatible metadata. This book proposed a solution to address geospatial metadata interoperability and compatibility issues.
