Jun 29, 2011 at 23:13 comment added whuber (+1) There is, however, a convention for orienting coordinate systems. According to this convention, for example, (x,y) is positive while (y,x) is negative. On the sphere, (lat,lon) is negative while (lon,lat) is positive (taking western longitudes and southern latitudes to be negative numbers, which seems to be universal). Therefore, if you want to use a consistent orientation for coordinate systems, you will use (easting, northing) on your maps and (lon, lat) on the sphere.
