Physical Environment
a place to discuss and follow the work

Knowledgeable WG members: briana sullivan (UNH), Wilfred den Toom (NL), Tom Loeper (USA), Yves Le Franc (SHOM)

OLD ORIGINAL - Sample Test Data File:Physical Environment Test Data Sample.docx (NOTE: we are now using real samples from US Coast Pilot and US Sailing Directions)

NEW listing of terms with data source (Annex A)

File:Coast Chart Term Frequency NIPWG Version.xlsx - a new list of terms compiled from all possible sources related to the Physical Environment that contains statistics on the frequency of word use within the 9 volumes of the US Coast Pilot. It will be used as a guide to focus on terms to research and build use case scenarios so we know what is of value to model and what doesn't need representation.
