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 l.jpg

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 l.jpg

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 l.jpg

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 l.jpg

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 l.jpg

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)


Slide8 l.jpg

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 l.jpg

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 l.jpg

IBNet geographically

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


Ibnet main modules l.jpg

IBNet main modules

  • 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 l.jpg

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.
