Cylindrical projection is a map projection on which meridians of normal aspect are mapped by straight parallel lines at the distance proportional to the differences between the corresponding longitudes of the meridians, and parallels by straight parallel lines ortogonal to meridians, at the distances depending on mapping conditions.
There are many different cylindrical projections. One of them is the Mercator projection.
