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.

7
What is a Route Topology Model (RTM) /2

• The node domain

8
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).

11
How can a RTM be portrayed?
Different users need different portrayal modes ?
different applications provide different
portrayal modes.
12
Portrayal modes tailored to RTM applications /1

• Three fundamentally different portrayal modes
  have been identified
• ENC/ECDIS Layer Mode
• London Tube Map Mode
• Head-up Display/Augmented Reality Mode

13
Portrayal modes tailored to RTM applications /2

• 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 vessels voyage.
The Motorways of the Sea (MoS) of the NSR

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

Portrayal modes tailored to RTM applications /4
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)
16
Portrayal modes tailored to RTM applications /5

• Co-existence of different modes of portrayal for
  different applications (onboard and ashore)
• Scalability as required by IMOs e-Navigation
  strategy

17
Portrayal modes tailored to RTM applications /6
All modes of portrayal / all applications are
driven by the very same database This is
harmonization in the spirit of e-Navigation!
