ISO 19156:2017 is an international standard that provides a framework for the observation and measurements in the field of geospatial information. It specifies concepts, models, and practices related to observations, as well as the way they can be collected, stored, and shared.
The Importance of ISO 19156:2017
ISO 19156:2017 plays a vital role in ensuring consistency and interoperability of geospatial data across different systems and organizations. With the increasing reliance on geospatial information for decision-making and analysis, having standardized processes and formats becomes crucial. The standard also promotes transparency and trust in observational data, as it establishes guidelines for accuracy assessment and quality control of observations.
Main Elements of ISO 19156:2017
ISO 19156:2017 consists of several key components. Firstly, it defines the conceptual framework for observations, including the basic terminology and relationships between different entities involved in the observation process. It also describes the procedures for encoding observations into machine-readable formats, ensuring that the data is easily shareable and interoperable.
Another important element of ISO 19156:2017 is the specification of metadata for observations. This includes information about the data collection method, instrumentation used, temporal and spatial coverage, and any specific constraints or limitations associated with the observations. Metadata enables users to understand the context and reliability of the observations, enhancing the usability and credibility of the data.
Additionally, the standard outlines best practices for validating and assessing the quality of observations. It provides guidance on how to evaluate the accuracy, precision, and completeness of collected data, ensuring that it meets the intended purposes and satisfies the required quality criteria.
Lastly, ISO 19156:2017 incorporates the concept of observation services, allowing for the discovery, access, and integration of observations from various sources. Observation services facilitate the seamless exchange of observational data between different systems, making it easier for organizations to collaborate and share information.
Conclusion
ISO 19156:2017 is a crucial standard in the field of geospatial information, providing a comprehensive framework for observations and measurements. Its adoption ensures consistency, interoperability, and quality control of observational data across various systems and organizations. By following the guidelines outlined in the standard, stakeholders can enhance the trustworthiness, reliability, and usability of geospatial information, contributing to better decision-making and analysis.
