GRAPHICAL CONSTRUCTION OF THE GNOMONIC MAP PROJECTION

John P. Snyder

Peer Reviewed

Abstract:	The gnomonic map is plotted by projecting the latitudes and longitudes of the earth’s surface from the center of the globe onto a tangent plane. If we assume a spherical earth, this azimuthal projection will show all great-circle paths as straight lines, but less than one hemisphere can be shown on a single map, and the distortion in shape and area is considerable over much of the map.
