VTT TECHNICAL RESEARCH CENTRE OF FINLAND
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)

VTT TECHNICAL RESEARCH CENTRE OF FINLAND
IceMap on Linux - licensing options

• 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

• 2003 gtLinux version
• 2003 gt 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

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.
