Great circles.
figure
It depends on the shape, whether or not it is regular, etc.
to calculate square feet you need a 2d shape
It is to calculate the extent of the shape in 2-dimensional space.
You can calculate the longitude of a place when time is given using the Greenwich solar time.
Great circles.
We use longitude and latitude when looking at a map to calculate time.
The great wall of china has no approximate or specific longitude you would have to break the wall into segments an calculate their individual longitude.
GPS receivers do not 'use' elevation for anything. They use the signals from several satellites simultaneously to calculate the latitude, longitude, and elevation of the receiver's location. It takes a minimum of three satellites to calculate the latitude and longitude, a minimum of four satellites to calculate the latitude, longitude, and elevation, if more satellites can be found the latitude, longitude, and elevation calculations can be refined more accurately.
