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



IceMap on Linux - licensing options

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

FIMR’s latest operational product to users at sea (in experimental use in

2003)


Resolution ~500 x 500 m


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.
