Map-based portals are increasingly being recognised for their use in marine science communication, with enhancement, connectivity and interoperability of data between map-based portals a key challenge. This report outlines the results of consultations with data experts on a pathway for map-based portals to adopt Open Geospatial Consortium (OGC) and ISO compliant standards to enable the discovery of raw data, summarised and curated data products. A case study using the GlobalArchive.org platform is presented using the ‘FishNClips’ and ‘Visualiser’ tools. This report provides a pathway for the future enhancement, connectivity and interoperability of map-based portals to meet standards to enable the discovery of data and communication products such as interactive imagery and data visualisations.
