The cone is unrolled, and the parallel that was touching the sphere is assigned unit scale. That parallel is called the standard parallel. By scaling the resulting map, two parallels can be assigned unit scale, with scale decreasing between the two parallels and increasing outside them. This gives the map two standard parallels.
The 49th parallel north is a circle of latitude that is 49° north of Earth's equator. It crosses Europe , Asia , the Pacific Ocean , North America , and the Atlantic Ocean .
