For an efficient and advanced spatio-temporal analysis, reported information of vessels locations and behaviours must be cross checked with others and cartographical data. Amongst cartographical information, the International Hydrographic Organisation (IHO) defined a vector interchange format used for maritime charts. From this format (S-57 or its revision S-100) ensues the ENC (Electronic Nautical Chart) product specification use in electronic chart display and traffic control visualisation. It provides a data structure and format that are used to implement a data model and characterises spatial entities and geometrical primitives. The dataset labelled 10.5281/zenodo.1167595 contains ships' information collected though the Automatic Identification System (AIS), prepared together with a set of related data having spatial and temporal dimensions aligned. This technical note provides additional information for the integration of S57 nautical charts in this dataset.
