Preliminary Mapping and Assignment of Geometries for Traffic Management Test Data

This document outlines the work timeline and analysis of a traffic management test data set, including the division of text into smaller blocks for easier analysis. It also provides a sample extract of mapped areas to be avoided and the assignment of geometries to the test data set, covering ship reporting systems, traffic control services, and regulatory reporting requirements.

1. UNCLASSIFIED Traffic Management Test Data Set Preliminary Mapping and Assignment of Geometries (S-127) Michael Kushla (NGA) 6 December 2016 UNCLASSIFIED 1 1

2. UNCLASSIFIED 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). 2

3. UNCLASSIFIED 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. 3

4. UNCLASSIFIED 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.

5. UNCLASSIFIED 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. 5

6. UNCLASSIFIED Sample Assigned Geometries from Annex B of NIPWG 3-24.1 Interactive Traffic Control Polygon. Coast and lines joining indicated positions. Arc by center point and radius (ISO 19136). Point. Lines. Arc by center point and radius (ISO 19136). Passive Traffic Control Polygon. Lines joining indicated positions. Sector by center point and radius (ISO 19107). Polygon. Lines joining indicated positions. Circle by center point and radius (ISO 19136). Polygon. Coast and lines joining indicated positions. Line.

7. UNCLASSIFIED 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. 7

8. UNCLASSIFIED Recommendations Need to develop, at a minimum, new features and Attributes in the Wiki Feature Catalog for better modeling. Feature Attributes Bascule bridge Fixed bridge Pipeline Pontoon bridge Power line Length Depth Project depth Barge Break bulk Bulk liquid Bulk solid Chain ferry Chemical Container Cruise ship Ferry Swing bridge Vertical lift bridge (closed) Vertical lift bridge (open) Vertical clearance Horizontal clearance Dredged depth Maintained depth Overhead Obstructions Dredged Channels General cargo Hydrofoil Livestock carrier LNG LPG Project cargo Ro-ro Tug Vessel Type 8

9. UNCLASSIFIED 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. 9
