and longitude. Through these projected intersections the 

 meridians and parallels of latitude are drawn. 



In this projection, places near the point of tangency 

 have their outlines correctly reproduced, but the farther 

 away a place is from this point, the greater the distortion. 

 This distortion, however, is never as great as that at the 

 north and south in the cylindrical or Mercator projections. 

 In the stereographic projection, however, the directions 

 north and south and east and west must be traced on a 

 curved line, thus making it much more difficult to tell at 

 a glance the direction of one place from another. It is 

 not possible on this projection to show more than one 

 half the earth's surface on a single map.
