MACHC Marine Spatial Data Infrastructure Working Group (MMSDIWG)

Chair: Jim Rogers (US/NGA)
Vice-Chair: Amy Northern (UK/UKHO)

MMSDI Working Group Documents

The MACHC seeks to promote the development of MSDI within the region in support of numerous non-navigation users of marine (hydrographic / charting) data. The MACHC MSDI effort will be based on the four pillars of MSDI which create the framework necessary. These pillars include Policy & Governance (People), Technical Standards (Standards), Information Systems (ICT), and Geographic Content (Data). Making marine (hydrographic / charting) information available in the MACHC region will improve decision making in several areas to include marine planning, coastal zone management, and emergency response. One of the main activities of the MMSDIWG has been the development of an inventory survey.
