Some IICWG 2000 Issues
3
Future Sensors Satellites

• Data from present satellites do not fully meet
  the requirements of DMI !
• DMI consequently intends to exploit data from new
  satellites - primarily ENVISAT and RADARSAT-2
• Better coverage in time and space
• Less vulnerable to technical failures
• Increased possibilities for handling difficult
  ice situations
• Competition leads (hopefully) to lower prices

4
Future Sensors Satellites

• Ice services do have common demands e.g.
• Data processing and quality
• Data continuity
• Sensor types
• Scheduling and planning
• Data transfer compression
• Data formats

ACTION IICWG should identify common requirements
and lobby the data providers
5
Sharing Satellite Data

• DMI is interested in sharing Radarsat and Envisat
  data to have access to a larger pool of data
• We have to address some important issues related
  to data sharing
• Contractual issues
• Issues related to use of data
• Time critical products
• Less time critical products
• Practical issues
• E.g. communication, compression and planning

ACTION IICWG should establish a working group to
identify possible ways of data sharing
6
From Data to Information

• Use and exchange of digital ice information will
  increase during the coming years
• IICWG is an ideal forum for the exchange of ideas
  on digital ice charts and products

7
From Data to Information

• Will influence internal and external use of ice
  information
• Ice attribute standards
• Spatial information, positions and topology
• Additional information, e.g. on accuracy and
  source identification

Spatial Elements and Attributes
8
From Data to Information

• Adaptation of WMO standards to the digital future
• Symbols, line types and colours

Symbolisation Schemes
9
From Data to Information

• Exchange of ideas on presentation of ice
  information to end users
• End user presentation systems
• Ice information on the Internet
• Combination of information layers
• ECDIS

End User Presentation

From Data to Information
ACTION It is suggested that an IICWG subgroup is
formed to identify and analyse areas of common
interest within the field of digital ice charts
11
Training and Tutorials

• The IICWG should promote training and fruitful
  exchange of knowledge and methods
• SAR interpretation
• Combination of information and data layers
• Available tools
• Quality control
• and exchange training material
• Is Ice Tutor sufficiently flexible and open ?

ACTION IICWG should organise an ice analyst
workshop
12
Research and Development

• DMI research priorities
• Development of tools which will improve the ice
  analyst ability to correctly interpret SAR
  imagery
• Detection of low concentration ice
• Detection of icebergs

13
Research and Development
ACTION Interpretation of SAR images is a
common problem - how can we address it ?

• IICWG should promote collaborative research and
  exchange of information
• Fruitful collaboration has already been
  established
• Iceberg data from CIS and IIP
• ARKTOS software from NIC
• Future research and development
• Combined use of ice drift models and ice analysis
  ?
• Exploitation of ENVISAT ASAR data....
• Exchange of validation data, e.g. US Healys
  mission to West Greenland

ACTION List research priorities of the ice
centres and identify possible areas of
collaboration
