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

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)
• 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

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???
Preliminary results of the grid-pointextraction 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.
