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 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

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 grid-files). 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)

• 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

IBNet geographically
VSAT satellite connection to the ”big” icebreakers , up to 512 kbit/s

IBNet main modules

IBPlott-Map user interface
IBBridge-Form based
user interface
IBOperator- Operator’s tool
IBStatistics- Follow up
and statistics
• 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.
