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 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.

the Sea (MoS) of

the NSR

2. the “London Tube Map Mode”


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”


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




- 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!
