VTT TECHNICAL RESEARCH CENTRE OF FINLAND VTT Technical Research Centre of Finland/ Robin Berglund ICEMAP main features today 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) Implemented using C++, X-Windows, Motif

Slide4: 

VTT TECHNICAL RESEARCH CENTRE OF FINLAND VTT Technical Research Centre of Finland/ Robin Berglund 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. Experimental at this stage (waits for the color standard to be finalized) Additional attributes for the ice polygons related to ice ridging. Enabling of dynamic addition of new attributes. Output according to SIGRID-3 (under investigation) Line simplification to reduce size of output file. Useful for possible transfer of vector formats over slow links. (Not implemented yet)

Slide5: 

Linux-version will be prototyped in a research project (IRIS). Prototype will be made available to participants in the IRIS project (FIMR, SMHI) Possibility to have access to the source code will be offered. Enables development of enhancements and in-house support without dependency on VTT. Conditions still to be agreed upon. copy of corrections/improvements also sent back to VTT for use within own organization only VTT TECHNICAL RESEARCH CENTRE OF FINLAND VTT Technical Research Centre of Finland/ Robin Berglund IceMap on Linux - licensing options

Slide7: 

Each ice area contains: Thickness (avg.): xxx cm Thickness (min.): xxx cm Thickness (max.): xxx cm Concentration: xxx % Degree of ridging: x unit 0= no deformation 1= rafted ice 2= weakly ridged ice 3= ridged ice 4= heavily ridged ice 5= brash ice barrier Ice forecast SAR algorithm based products

Slide9: 

Architecture used in the Baltic Sea

Slide10: 

Data to the icebreakers and ships: IBPlott system for icebreakers IceView for ships An example of the icebreaker IBPlott system

Slide11: 

Ice charts and satellite data to icebreakers and ships in digital format

Slide12: 

Ice thickness classification Combination of SAR image algorithms & ground truth measurements FIMR’s latest operational product to users at sea (in experimental use in 2003) Resolution ~500 x 500 m

Slide13: 

Future ice charting system: IceMap 2003 =>Linux version 2003 => Source code to users ArcGIS Other possibilities ???????????????? We have not desided the future system: IceMap could be used for several years Other possibilities will be studied Today: Workstations Future: PCs???

Slide14: 

Preliminary results of the grid-point extraction from the operative IceMap ice charts (chart is 2003-02-27). Information will be submitted to GDSIDB. Data base covers 1960-2003. Remaining 2 years of Baltic Sea ice digitalization project (1980/81 and 81/82) will be finalized in summer of 2003. Torbjorn Grafstrom SMHI IICWG-4, St. Petersburg, Russia, 7-10 April 2003 / A.
