Mapping Software and GIS Glossary
A Great Circle is any circle that circumnavigates the Earth and passes through the center of the Earth. A great circle always divides the Earth in half, thus the Equator is a great circle (but no other latitudes) and all lines of longitude are great circles. The shortest distance between any two points on the Earth lies along a great circle.
Great circles intersect the center of the Earth and divide the Earth in half. The shortest distance between any two locations on the Earth, such as New York City and New Delhi, lies along a great circle.
