On April 2, 2013, an informal working group of twenty-five (including four Esri staffers) participated in a 1.5-hour webinar to discuss the development of a new, improved version of the\u00a0Arc Marine Data Model<\/a><\/b>\u00a0(also known as the \u201cMarine Data Model\u201d). This is an action item following on from the\u00a0Esri Oceans Summit<\/a><\/b>\u00a0in November 2012, where great interest was shown in updating and thus improving the model.<\/p>\n

The Arc Marine data model was first widely released and published in a\u00a0research monograph by Esri Press<\/a><\/b>\u00a0in 2007. Despite the age of the model, its utility is still recognized and adoption of it appears to be ongoing, with several organizations seeking to standardize on it, particularly in Europe. Given the apparent demand for the model in the ocean community, Esri is going to fully support the model as a community-based information model\/template. To this end, I have assigned my ocean GIS product engineer, Shaun Walbridge, to learn the structure of the old 2007 model and to bring the\u00a0Unified Modeling Language (UML)<\/a>code up to compliance as appropriate, so that it works with our latest Esri technologies (chief among them ArcGIS for Desktop 10.1, and implementation in a file geodatabase rather than just a personal geodatabase). We are initially looking at updating the UML, realizing at the same time that there are now a variety of standards efforts for communities, data formats, metadata, etc. We want to consider how to leverage existing or emerging standards efforts. One issue is going to be that the physical data structure need not be constrained by any one category. For example, it is now common for people to use netCDF as a container not only for gridded model data, but also for time series points and trajectories. And our software can do it either way.<\/p>\n

The following topics were discussed during the webinar:<\/p>\n
