|
|
conical projections.
|
|
|
geometric meridians.
|
|
|
great circle routes.
|
|
|
longitudinal circle lines.

Explanation:
Detailed explanation-1: -In general, the shortest distance between two points is a geodesic curve. It turns out that the plane is the only surface that has nothing but lines as geodesics-that is, lines only minimize distance in flat space. On a sphere, for example, geodesics are great circles .
Detailed explanation-2: -great circle route, the shortest course between two points on the surface of a sphere. It lies in a plane that intersects the sphere’s centre and was known by mathematicians before the time of Columbus.
Detailed explanation-3: -d = r × t1+ t2 This is the great circle distance.
