Traffic Management Test Data Set—Preliminary Mapping and Assignment of Geometries (S-127) Michael Kushla (NGA) 6 December 2016 UNCLASSIFIED 1 Version 8; 28 Feb 2011; 4:15 PM

Work Timeline Pre-SNPWG 16—Survey to experienced mariners and ECDIS training facilities. SNPWG 16--Develop the Traffic Management Test Data Set and present at SNPWG 17 (Silver Spring). SNPWG 17—Presented first draft of test data set. Prepare and present second draft at SNPWG 18 (Rostock). SNPWG 18—Presented second draft of test data set. Prepare and present third draft at NIPWG 1 (Cadiz). NIPWG 1—Presented third draft of test data set. Determined to be stable and ready for preliminary mapping (Monaco). NIPWG 2—Prepare preliminary mapping and assign geometries (Monaco). NIPWG 3—Presentation of preliminary mapping of the test data set and the assigned geometries (Busan).

Analysis Text divided into smaller discrete blocks of text for easier analysis. Total of 236 Features and Attributes from IHO NIPWG Wiki Feature Catalog: Information Features—10 items. Geographic Features—32 items. Simple Attributes—166 items. Complex Attributes—29 items.

Sample Mapped Extract from Annex A of NIPWG 3-24.1 2.2.2 Areas to be Avoided An IMO-adopted Area to be Avoided is bounded by lines joining the following positions: a. 30°50.0´S, 060°55.9´E. b. 30°50.0´S, 061°02.0´E. c. 30°55.0´S, 061°05.0´E. d. 30°58.0´S, 061°03.0´E. e. 30°58.0´S, 060°57.4´E. This area is located within the boundaries of the Jussland Right Whale Ship Reporting System. This area protects the nursing grounds of the Jussland Right Whale. In order to protect these animals from being interfered with during their nursing activities, vessels are prohibited from entering in or transiting through this area. For further information, see the Jussland Right Whale Reporting System.

Assigning Geometries to the Test Data Set The Traffic Management Test Data Set consists of the following: Ship Reporting Systems—Two voluntary systems, two mandatory systems, and two seasonal systems. Traffic Control Services—Interactive traffic control (two items), passive traffic control (four items), and traffic control signals (two items). Regulatory Reporting Requirements—Six items. Each system and item above was assigned a particular geometry after a visual inspection of each system or item: Worldwide coverage with no defined geometry. Point. Line. Arc. Circle. Polygon.

Sample Assigned Geometries from Annex B of NIPWG 3-24.1 Interactive Traffic Control Micklefirth Vessel Traffic Service Polygon. Coast and lines joining indicated positions. Arc by center point and radius (ISO 19136). Point. Micklefirth Pilotage Lines. Passive Traffic Control Firing and Exercise Areas Polygon. Lines joining indicated positions. Sector by center point and radius (ISO 19107). Areas to be Avoided Mined Areas Circle by center point and radius (ISO 19136). Tracks and Routes Line.

Conclusions NIPWG test data sets are very text oriented as opposed to the symbol-oriented ENCs. Difficult to select proper Features and corresponding Attributes, if any. In many cases, existing Attributes did not accurately convey the test data set information.

Recommendations Need to develop, at a minimum, new features and Attributes in the Wiki Feature Catalog for better modeling. Feature Attributes Overhead Obstructions Bascule bridge Swing bridge Fixed bridge Vertical lift bridge (closed) Pipeline Vertical lift bridge (open) Pontoon bridge Vertical clearance Power line Horizontal clearance Dredged Channels Length Dredged depth Depth Maintained depth Project depth   Vessel Type Barge General cargo Break bulk Hydrofoil Bulk liquid Livestock carrier Bulk solid LNG Chain ferry LPG Chemical Project cargo Container Ro-ro Cruise ship Tug Ferry

Recommendations (continued) Have the group review the mapping and determine what has been mapped correctly, what has been mapped incorrectly, and how the mapping can be improved. Share this with the S-100 WG and the Nautical Cartography WG.
