This shapefile was prepared by INSROP Project I.4.2 as part of INSROP Phase 2.
It includes the center point of analysis squares in a 50x50 km grid, which
cover the whole of the ship navigation area along the routes selected within the
WP 1 framework. The X-axis of the calculation grid is parallel to the 130°E
meridian and the Y-axis is parallel to the 140°W meridian. The southward axis
directions were assumed to be positive directions. In the adopted coordinate system
the North Pole has the following coordinates Xp=650 km, Yp=2150 km.
