Abstract
We provide a precise mathematical definition of map distortion, and we introduce several map projections that have minimal distortion for certain specific regions of the Earth (namely, regions whose boundary consists of one or two parallels of latitude). The minimizing projections for these regions will all have normal aspect. We show that oblique aspect projections have the same distortion properties as their normal aspect counterparts on earth regions bounded by one lesser circle or by two lesser circles lying in parallel planes. We summarize the good consequences of having small distortion, and we outline a strategy for finding the best oblique map projection of least distortion for any region on the Earth. We then implement that strategy to find projections of least distortion for some unusually shaped countries, states and other regions.
