History of Carlos Silva - Sao Paulo, Brasil
Conic Projection: The map is constructed by imagining it drawn on a cone that surrounds the Earth's sphere, which is then rolled out.
Advantages: Respects the contours and areas of the polar regions;
Disadvantages: Distorts all other regions , especially the equatorial and polar ones. It only represents one hemisphere at a time.
Ptolemy was the first cartologist to use this projection in the creation of maps.
A sheet of paper is placed in a cone on the globe and the earth's surface covered is projected. The deformation is smaller in the areas where the sheet touches the globe.
Note: Uses a cone as a projection surface. In polar equatorial regions, greater deformation is observed in this type of projection, since these areas are further away from the contact line (line of tangency) between the cone and the Earth's surface.
