Since the activities in the South Atlantic Overseas Territories started in September 2013, the IMS-GIS (Information Management System and Geographic Information System) Data Centre has demonstrated that continuity and engagement with local stakeholders is fundamental for the realisation and establishment of a central and standard system for data management, accessibility and sharing in the region. The Data Centre is contributing to the enhancement of data science and data services in the South Atlantic UKOTs and in other islands and territories that shows similar needs and interest in making their data a usable and accessible asset.
