Digital Mapping, Charting, and Geodesy Analysis Program (DMAP) Technical Review of Proposed Ice Objects for AML

摘要

The United Kingdom Hydrographic Office requested a review of proposals received for incorporating ice objects into the Additional Military Layers (AML) product. Two proposals were made by the Canadian Ice Service: (1) No amendments arc necessary to ice objects in Maritime Foundation and Facilities (MFF) product specification, and (2) High Resolution Environment (HRE) (or Environment, Seabed, and Beach (ESB)) is revised to bring it into line with the ECDIS Ice Objects Version 3.0, but without extending the scope of HRE. It is noted that MFF and HRE (or ESB) both contain Sea Ice-Ice Area and Land Ice-Ice Area. Separate consideration will be given to removing all ice from MFF to ensure that there is no duplication of data (or to confirming that there are different specifications for different purposes).
