The Fishhook Projection is a type of map projection developed by Arthur H. Robinson in 1963. It is a modified version of the Robinson projection, which was designed to reduce the distortion of land masses near the poles. The Fishhook Projection is an equal-area projection, meaning that it preserves the area of any given region on the map. The term 'Fishhook' comes from the shape of the projection, which resembles a fishhook. The BARB portion of the crossword solution refers to the 'BARB' lines, which are used to indicate direction and wind speed on the map.
