ISO-TR 19120:2016, also known as Technical Report (TR) 19120, is a comprehensive document that provides guidelines for the development and implementation of metadata in geographic information. Metadata, commonly referred to as "data about data," plays a crucial role in organizing and describing geographic information to ensure its accuracy, accessibility, and interoperability.
Importance of ISO-TR 19120:2016
The adoption of ISO-TR 19120:2016 is essential for organizations and individuals working with geographic information systems (GIS) and related technologies. This technical report establishes a standard framework for documenting and managing metadata, facilitating the discovery, integration, and use of geospatial data across various platforms and applications.
By following the guidelines outlined in ISO-TR 19120:2016, users can enhance data sharing and collaboration, optimize data searchability, and minimize errors and inconsistencies in geospatial datasets. Furthermore, conforming to this international standard ensures compatibility between different GIS software and promotes interoperability within the global geospatial community.
Key Components of ISO-TR 19120:2016
ISO-TR 19120:2016 provides a comprehensive set of guidelines for creating robust metadata descriptions. The key components include:
1. Metadata Content: This section outlines the necessary elements and attributes required for describing geographic information accurately. It covers different categories such as identification, spatial representation, data quality, and distribution information.
2. Metadata Structure: ISO-TR 19120:2016 defines the structure and organization of metadata through standardized XML schema. This XML-based format ensures consistency and compatibility across diverse systems and applications.
3. Metadata Implementation: This part offers practical guidance on implementing metadata within GIS environments. It covers the process of creating, documenting, storing, and disseminating metadata to ensure its effective utilization.
Conclusion
ISO-TR 19120:2016 plays a pivotal role in establishing a standardized approach to geospatial metadata. By adhering to this technical report, organizations and individuals can benefit from enhanced data sharing, improved interoperability, and streamlined geospatial workflows. As technology continues to advance and the demand for accurate and accessible geographic information increases, ISO-TR 19120:2016 remains an indispensable tool for the geospatial community.
