Presentation purpose and contents
• Purpose: to give an overview of the
present status of IceMap and to present
how ice information is transferred and
used by one important end user group: the
icebreakers.
• Contents:
– IceMap
– IBNet, IBPlott systems

VTT TECHNICAL RESEARCH CENTRE OF FINLAND
VTT Information Technology
• A government owned research institute
• We help companies derive maximum benefit
from the rapid progress in microelectronics,
information technology and media technology.
• About 400 employees, annual turnover 40 M€
• Remote sensing is one of the research areas
• IceMap is one example of a Customer specific
systems development

IceMap
• An interactive editing tool for creating maps using satellite images as
templates
• Based on polygon networks: attibutes can be assigned to areas
defined as polygons. These attributes are related to the visual
appearance (hatching), but also to properties like ice thickness etc.
• Output formats: Postscript, Grid (attribute values at regular sampled
intervals), area sizes and types per area. Other formats can be
generated from the Postscript output (PDF, raster)
• Possibility to read temperature measurements directly from file and
plot them on the map
• Isotherm generation
• Tailored to the needs of the Ice services around the Baltic Sea.
• Runs on a Unix workstation (HP-Unix, Digital Unix, SUN Solaris,
Linux)
• Implemented using C++, X-Windows, Motif

IceMap status today
• Development mainly in Linux, latest version
3.2. This version used as a tool in research
projects (IRIS: Ice Ridging Information for Decision
Making in Shipping Operations )
• Versions in operational use :
– FIMR: HP, ver 3.1.2.3
– BSH: Sun Solaris 7, ver 3.0.3
– SMHI. Digital Unix, ver 2.8.4
• Windows version prototyped

VTT TECHNICAL RESEARCH CENTRE OF FINLAND
ICEMAP recent additions and
future enhancement ideas
• Possibility to run IceMap in batch-mode. Enables automated production
of charts for separate areas and in different formats (including gridfiles). Used at FIMR Ice Service.
• Automatic coloring of charts according to ice polygon attributes using
color standard guidelines. Experimental at this stage
• Additional attributes for the ice polygons related to ice ridging. Enables
dynamic addition of new attributes.
• Line simplification to reduce size of output file. Useful for possible
transfer of vector formats over slow links or for resolution reduction for
other purposes.
• Windows version (requires Cygwin license)
• Output according to SIGRID-3 (if required, implementation not there
yet)

VTT TECHNICAL RESEARCH CENTRE OF FINLAND
IceMap on Linux - licensing options
• Linux-version is prototyped in a research project (IRIS).
Prototype will be made available to participants in the IRIS
project (FIMR, SMHI)
• Licensing option including source code access may be offered
to anybody interested. Enables development of enhancements
and in-house support without dependency on VTT. Terms and
conditions available on request.
– copy of corrections/improvements also sent back to VTT
– for use within own organization only

IBNet – the End User System on
the icebreakers
• Traffic information system for icebreakers
• Contract assignment by the Finnish and
Swedish Maritime Authorities (jointly)
• Now in operational use in 2 centers + 20 nodes,
about 50 client installations, 24/7 utilization in
wintertime.
• During a season over 200 Mbytes of data is
generated in one replicated database (excluding
satellite image data)
• Utilization of satellite images essential

• Input on one IBNet node, on an icebreaker for
example, is automaticaly replicated, i.e transferred to
the other IBNet nodes.
• Certain operations can only be input by the IBNet
Operator, such as ice restrictions for ports, ship register
information etc.

VTT focus in the future
• Distribution and delivery aspects
– the Facade
– delivery tailored to customer capabilities and needs
• Architecture of distributed systems
– interoperability
– open systems
• (Archive)
– internally
– externally
• And: VTT sees no reason why IceMap could not have a
central role in the Ice Services still for many years to
come.
