Ice Charting System in the Baltic-an example

Robin Berglund, VTT Technical Research Centre of

Finland

IICWG 5th meeting, Hamburg/Rostock April 19-22, 2004

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


4

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


7

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)


8

• 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


12

IBNet geographically

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


13

IBNet main modules

IBNet

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.
