Which standard adds elements to describe imagery and gridded data as well as instrument-collected data?

The standard that adds elements to describe imagery and gridded data, as well as instrument-collected data, is ISO 19115-2. This part of the ISO 19115 series expands on the original metadata standard by providing specific guidance and an expanded framework for different types of geospatial data, including those related to remote sensing and sensor outputs. It ensures that metadata captures detailed information about how data was collected, the instruments used, and the nature of the data itself.

This is particularly important for users who need to understand the context and quality of imagery and gridded data for applications such as environmental monitoring, land use planning, and scientific research. By incorporating these specific elements, ISO 19115-2 enhances the ability to effectively utilize and share geospatial data across various platforms and disciplines.

Other standards listed, like ISO 19115, CSDGM, and ISO 19115-3:2016, either focus on broader metadata aspects or deal with different facets of geospatial data not specifically dedicated to imagery and gridded data. Thus, while they are relevant, they do not serve the same specialized purpose that ISO 19115-2 does.
