U.S.’s Goals for IICWG
• Jointly lobby funding agencies for operational applications component to major research efforts
• Digital exchange of ice charts in near-real time• Easy access to worldwide Ice Charts through a transparent
interface• Continued access to affordable sources of data• Collaborative training programs• Sharing of technology as allowed• Influence international standards for ice chart archiving and
metadata creation

New Initiatives at NIC
• Products are first vector files, then raster files– .E00 is primary file structure
– JPEG of “Egg Chart” and colored Total Thickness
• Upgrade of System
• Science and Applied Technology Department – Chief Scientist, 3 visiting scientists
– Scientific programmer, August 00
– Selection of two new post-docs, Sept. 00
• Computer Based Training
• Dedicated effort to convert remainder of legacy data
• EWG data released 12-13 Oct at Arctic Council Meeting

NIC System Upgrade Objectives
• Automatically detect & process incoming raster and vector data
• Provide analysts with a completely integrated remote sensing and GIS package
• Facilitate the transition of R&D products• Develop data model• Move to user defined products (dynamic vice
static)• Three phases, Ingest, Analysis, Distribution
