No matter how a map is made it is going to have geographic grids, which help us find and describe locations. These grids are affected in different ways by each of the projection methods.

Cylindrical projections are the projections of the globe onto a cylinder. The easiest way to understand cylindrical projection is to imagine a paper cylinder wrapped around an illuminated globe. The lines from the globe are then projected onto the cylinder in shadows and can be traced. When that is finished the cylinder is slit and unrolled. The problem with cylindrical projection is that there are very few lines that are free of distortion. The lines that are closest to the part of the cylinder that touched the globe are going to be more accurate, while the ones farther out are less accurate. This makes countries like Greenland loo
