A method of applying the geographic information system (GIS) to predict sea-ice distribution is proposed. The prediction
computations are performed using the distributed mass/discrete floe (DMDF) model. The GIS is used to prepare the initial data
for the DMDF model, and to display the simulation results together with a digital map and observational data for evaluation
and further use. Two areas in the Arctic Ocean were selected to test the computations in this study. The results of the case
studies show that this method can help with (1) free-area and free-scale prediction fitting for various purposes, (2) a high-resolution
output to provide more detailed data, and (3) a reasonable combination of different data sets to make the best use of the
information obtained. The results also suggest that the DMDF model is a good simulation of the ice motion not only for large-scale
but also for local-scale predictions.
