What are the advantages and disadvantages of the conic projection?

Answer 1

You can't see the southern part of the equator looking from the North Pole or you cant see the northern part of the globe.

Answer 3

I suspect that the three main map projections you have in mind would be:

Mercator, Tangential, and Conic.

The problem is that the surface of the earth is spherical, and a map is flat, so how to represent a curved surface on a flat surface?

The Mercator projection assumes you wrap a cylinder of paper round the sphere, only touching it at the equator, and project the map as if there was a light bulb at the center of the sphere.

Advantage: It is accurate at the equator.

Disadvantage: It becomes more and more distorted as you go farther away from the equator.

The Tangential projection assumes a flat piece of paper was placed so as to touch the sphere at some point of interest.

Advantage: Most accurate at the point of contact.

Disadvantage: Becomes more and more distorted as you move away from the point of contact.

The conic projection assumes a cone of paper was placed to touch the sphere around a circular locus, and the map is projected onto it. The circular locus can be a line of lattitude, or any other convenient circular line.

Advantage: Most accurate along the line of contact, which could be an intended line of travel.

Disadvantage: Becomes more and more distorted as you move away from the line of contact.

There are many other projections, most of which are hybrids or variations on the above.
