Integrity and trust of geographic information.

Abstract : This chapter presents the concepts of integrity and trust in the context of the assessment of spatial data quality. It describes approaches that can be used to assess the internal and external quality of geolocated information produced by mobile objects. The first step, a bottom‐up approach, suggests assessing the integrity of information based on the database structure. The second step, a top‐down approach, suggests assessing the trust that should be given to information based on the measures that can be applied to a dataset. Taking the example of geolocation data, in particular, in the context of maritime navigation, the chapter demonstrates how these concepts and methods may be used to define the integrity and trust of the data produced by a vessel monitoring system. Characterizing the integrity and trust of geographic information makes it possible to provide better information about the uncertainty of the data used in decision‐making processes in maritime safety.
