The Open Geospatial Consortium (OGC) seeks, in support of the OGC Federated Marine Spatial Data Infrastructure Pilot (Phase 3), to gather and identify the requirements and use cases for a regional/international MSDI via a short online survey. Responses are due by November 15, 2022. The survey will help shape the ongoing OGC FMSDI Pilot and potential future FMSDI activities to better serve the user community's needs. Feedback captured in the survey will be included in the OGC FMSDI (Phase 3) Engineering Report.
