Description: As navigation in the Arctic region becomes a reality due to the progressive melting of the Polar Ice Cap,
there is a need for cartographers and ECDIS manufacturers to develop and incorporate in their systems
software for suitable polar projections. Because of the large distortions in areas and angles that the
Mercator and other projections cause, the selection of a suitable projection for navigation in the Arctic
must be revisited. More specifically for the projections used in ECDIS and in order to ensure
commonality of display and simplify the task of both the user and the Type Approval authorities, there is
a need for standardization of the display through the use of suitable projections for the Arctic and the
sub Arctic areas. The study area for this project extends from 50° to 90° [lat] although the Arctic Region
itself is considered to be north of the 68th parallel (fig.1). This is due to the fact that it was considered
necessary to address the issue of the selection of suitable projections for the sub-Arctic Region.
