‘Data supply chain certification’ - quality monitoring and indication for e-Navigation solution reliability

Abstract

In the ever more complex environment navigators need support by integrated systems to ensure Situational Awareness. The concepts of “Ship Domain” and “Ship Arena” are appropriate approaches to evaluate the situational centric risk. Generally, the qualification of SD approach for reliable decision finding requires more research to better define the different factors influencing the ship domain (static/dynamic); and the provision of means to determine and monitor error budgets within integrated systems. In particular, human factors may need an improved quantification of errors & risks; standardized data quality indicators are needed (e.g. see IHO DQWG); DSCC (static/dynamic) needs to be established to ensure the reliable data supply error budget and to indicate the level in during delivery.
