The MAP-Guided Ice Classification (MAGIC) system is designed specifically to read and interpret synthetic aperture radar (SAR) sea ice images using associated ice maps as provided by the Canadian Ice Service (CIS). An ice chart is manually created at the CIS based on the corresponding SAR image and other ancillary data to provide ice concentrations, types, and floe sizes within enclosed ‘‘polygon’’ regions. MAGIC uses such information as input and then generates a sensor resolution (pixel-based) ice map for each polygon, a product not feasibly produced manually. The primary feature of the current MAGIC version 3.1 is its segmentation module, which is evaluated successfully on a number of images. MAGIC is designed to be used not only as a specific tool for sea ice interpretation but also as a general platform for interpreting generic digital imagery using implemented fundamental and advanced algorithms.
