A mathematical formula used to represent the curved surface of the Earth on the flat surface of a map is
|
|
a cylindrical projection.
|
|
|
a planar projection.
|
|
|
a map projection.
|
|
|
a conic projection.
|
Explanation:
Detailed explanation-1: -Therefore, more generally, a map projection is any method of flattening a continuous curved surface onto a plane. The most well-known map projection is the Mercator projection .
Detailed explanation-2: -The globe is naturally parameterized in terms of two variables, latitude and longitude . Thus, we could think of a map projection as a function T : R2 → R2 or T(, )=(x(, ), y(, )). The earth, as we well know, is approximately spherical; it is best represented as a globe.
Detailed explanation-3: -A map projection is any of many methods used in cartography (mapmaking) to represent the two-dimensional curved surface of the earth or other body on a plane.
