  1. 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

  2. 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

  3. 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

  6. 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. 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

  9. 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

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

  11. 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.

  15. IBPlott • Satellite images • NOAA and RADARSAT, now also ENVISAT • Traffic situation • Both icebreakers and ships • DirWays • Icechart • Weather forecast and observations

  16. ViewIce (= IBPlott for merchant ships) • Functionality as in IBPlott, but no traffic situation information • Ice charts • Satellite images • Weather prognosis • Wave forecasts

  26. 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.
