WebCylindrical Projection. A cylindrical projection is a type of projection for mapping a portion of the surface of a sphere to a flat image. It can be envisioned by imagining wrapping a flat piece of paper around the circumference of a sphere, such that it is tangent to the sphere at its equator. Shining a light from the center of the sphere then ... http://www.paulbourke.net/dome/fish2pannini/ deriding his creation https://connectedcompliancecorp.com
