What guidelines does the ISO 191 Metadata Series provide?

The ISO 191 Metadata Series primarily focuses on establishing a framework for creating consistent, high-quality metadata for geographic and spatial data. This series outlines the principles and requirements for documenting data in order to improve accessibility and usability, ensuring that datasets can be understood and utilized effectively by users.

Consistent metadata allows for clear communication of data attributes, origin, lineage, and other critical information that supports data discovery and interoperability across different systems and organizations. The emphasis on consistency helps to standardize how geographic data is represented, making it easier for various stakeholders to find, evaluate, and apply the pertinent data to their needs.

While the other options encompass important aspects of geospatial data management and analysis, they do not align directly with the primary focus of the ISO 191 Metadata Series, which is specifically aimed at metadata creation and management rather than database building, data trends analysis, or structuring data formats.
