| Dataset Checklist |  |
The 'Dataset Checklist' offers a summary of the valid datasets. |
| Dataset Specification |  |
The Product Specification includes an overview of specification scope, data product identification, data content and structure, reference system, data quality, data capture, data maintenance, data portrayal, data product delivery, additional information, and metadata. This framework facilitates and supports the use and exchange of the digital dataset, enabling air navigation users to evaluate the product and determine if it meets their specific requirements for intended applications. |
