EC in its 2014 final report on the first phase of implementation of the Marine Strategy Framework Directive (2008/56/EC), has defined adequacy as an assessment of the reported information to meet the objectives of the Marine Strategy Framework Directive (MSFD) and its technical requirements. The Checkpoint adequacy is close to this definition but focused on several Challenges.

 Data adequacy can be defined as the fitness for use of the data for a particular user or for a variety of users. Since different applications require different properties associated with the data itself, ‘adequacy’ should be defined objectively using standardized nomenclature and methods.

The concept behind the quality of a dataset from a producer and a user point of view

Whereas the fitness for purpose describes the rationale for creating a dataset, the fitness for use describes the intended use, the rationale for selecting a dataset. The fitness for purpose is evaluated by the producer according to the specifications of the quality expected for his purpose. The fitness for use of a dataset is evaluated by the user according to the specifications of the quality expected for his use. The purpose of the Checkpoint is to provide an evaluation of the fitness for use of the datasets used by the Challenges.


Data product specification (ISO 19131)

The ISO quality standard principles provides the model to assess the effectiveness of a monitoring system or data collection strategy, quality of data and quality of services that fits the user’s defined requirements, under specified operational conditions (represented by the Challenges). The ISO 19157 standards for data quality and additional criteria are used to define the metadata specification for the Checkpoint data inventory and ISO 19113 specifies standard elements, sub-elements , measure and weight. whereas ISO 19131 provides the framework for data product specification, ISO 19115 and ISO 19119 the framework to describe input data and the associated service, There are all parts of the ISO/TC211 suite of standards for geographic information. Selected elements are discussed in the Literature Survey.

The assessment criteria per Territory. Raw assessment descriptors (checkpoint metadata – ISO 19114).


Input dataset are uniquely identified at level P03-P02 minimum, as a combination of (variable, dataset, intended use) or of (geographical feature, dataset, intended use) depending on their nature. They can be shared between challenges.

A method aggregating and scoring raw indicators has then be defined to offer a visual representation allowing a non expert to easily assess the fitness for use without spending a lot of time looking at metadata and reports.

The aggregation and scoring method has been conceived following the SMART principles (Significant, Measurable, for Actionable information, Reproducible, Time bound /managed for enhancement); the metadata catalogue is then harvested by software tools yielding dynamics statistics for these two fields of data quality.
