What is the significance of ISO 19115 for geospatial metadata in risk projects?

• A. It defines standardized geographic metadata, enabling interoperability, discoverability, data quality assessment, and lineage tracking
• B. It increases data size without benefit
• C. It removes metadata requirements
• D. It only applies to imagery, not vector data

Answer: (D)

Understanding geospatial metadata standards helps you describe data in a way that others can find, understand, and trust it. ISO 19115 provides a common framework for geographic metadata, outlining what the data are, who produced them, where and when they cover, how good their quality is, and how the data can be accessed and used. Because it’s a standard, software from different vendors can read and interpret the metadata consistently, enabling interoperability across systems, easier discovery, and reliable assessment of data quality and provenance. This applicability isn’t limited to imagery; ISO 19115 applies to all geographic data types, including vector data, raster data, and other spatial datasets, with possible extensions for imagery. In risk projects, having well-documented metadata supports transparency and reproducibility—you can trace data lineage, evaluate suitability, and communicate limitations to stakeholders. The notion that metadata standards apply only to imagery or that they simply increase data size or remove requirements doesn’t fit how metadata supports trust and reuse across geospatial work.
