The Advent of Marine Spatial Planning /1 The North Sea Region today and in Source: ACCSEAS GIS

The Advent of Marine Spatial Planning /2 Example of MSP in the German EEZ MSP is a fact, let’s face it! Source: BSH Germany “shipping lanes” with legal status

The Advent of Marine Spatial Planning /3 Mark “shipping lanes” Add junctions Add important port “nodes” Lift off RTM

What is a Route Topology Model (RTM) /1 - A Route Topology Model represents voyage/traffic relations -RTM comprises/ addresses two different domains: - A RTM is build by concatenation of legs. - An RTM is constructed by identifying and describing a network of “legs”, i.e. defined stretches of fairway/waterway between two “nodes” with defined attributes.

- The node domain What is a Route Topology Model (RTM) /2

What is a Route Topology Model (RTM) /3 - There is a generic RTM, ideally defined globally in a harmonized manner as part of the IMO envisaged Common Maritime Data Structure (CMDS) based on IHO S-100 framework; - There are many instances of RTM, one for each sea area under consideration, e.g. the North Sea Region (NSR)-RTM: NSR-RTM - Various applications build on this (once defined).

How to derive a RTM (for the NSR)? /1 IEC 62288:2013, Annex A, Table A.3.1b EU „Motorways of the Seas“ „artist‘s impression“ EU INSPIRE, “Transport Networks” Generic RTM Definition MonaLisa 2.0: Rydlinger/e-Navigation Underway 2014 SN.1/Circ.289: AIS ASM Route information IMO Res. A.893(21) „Guidelines for Voyage Planning“

How to derive a RTM (for the NSR)? /2 Use AIS footage + Marine Spatial Planning data of North Sea Region Database representation of (NSR-)RTM Source: BSH Germany Source: ACCSEAS GIS

How can a RTM be portrayed? Different users need different portrayal modes  different applications provide different portrayal modes. * IMO NAV57, WP6, Fig. 1

Portrayal modes tailored to RTM applications /1 Three fundamentally different portrayal modes have been identified: a)“ENC/ECDIS Layer Mode” a)“London Tube Map Mode” b)“Head-up Display/Augmented Reality Mode”

1. the “ENC/ECDIS Layer Mode” Chart-oriented / based; True topographical context; To be used for navigation (if based on certified ENC); Serves both tactical and strategic needs of a vessel’s voyage. Portrayal modes tailored to RTM applications /2 Source: ACCSEAS GIS The Motorways of the Sea (MoS) of the NSR

2. the “London Tube Map Mode” Portrayal modes tailored to RTM applications /3 Deliberately disregards exact topographical locations in favour of the abstraction to strategic essentials, such as “shipping lanes” => “reduce to the max” Example: Motorways of the Sea (MoS) along the German coast

3. The “Head-up Display/Augmented Reality Mode” Portrayal modes tailored to RTM applications /4 Just shows features visible/ relevant to the individual vessel in a given tactical situation; Creates awareness for up- coming situations regarding routes, such as nodes of rele- vance (bends, junctions, ports); Allows for Scheduled Time of Arrival (STA) clock display (ahead-of-time/lag-behind indi- cator);

ENC/ECDIS Layer Mode London Tube Map Mode Head-Up/Augmented Reality Mode ENC/ECDIS Layer Mode London Tube Map Mode Portrayal modes tailored to RTM applications /5 -Co-existence of different modes of portrayal for different applications (onboard and ashore) -Scalability as required by IMO’s e-Navigation strategy

All modes of portrayal / all applications are ‘driven’ by the very same database: This is harmonization in the spirit of e-Navigation! * IMO NAV57, WP6, Fig. 1 Route Topology Model ENC/ECDIS Layer Mode London Tube Map Mode Head-Up/Augmented Reality Mode ENC/ECDIS Layer Mode London Tube Map Mode Common Maritime Data Structure (CMDS) Portrayal modes tailored to RTM applications /6
