Conventional Projections

Under this heading are classed projections designed to be relatively easy to draw with the aid of drafting tools, but which do not correspond to any of the regular types.

These projections are compromise projections, although different ones choose to strike different balances between the rival goals of being conformal and being equal-area. Thus, the Globular projection is about midway between these two options, while the Van der Grinten projection moves only slightly in the direction of reducing area distortion at the cost of shape distortion.
