Presenter: Keith Treschman, Map Group and RGSQ Member
SYNOPSIS
It is impossible to transfer a spherical globe to a 2-dimensional surface without some distortion. The choice of a projection depends on what the map maker wants in terms of accuracy of area, shape, distance, or direction. Some major projections are covered along with their advantages and disadvantages.
