What's a map?

1. The concept of map derives from the Latin term map. It is a graphical representation and metric of a portion of territory over a two-dimensional surface, usually flat, although it can also be spherical as is the case of terrestrial globes. thanks to your metric properties, the map allows you to take measurements of distances, surfaces and angles, with virtually exact results. That is why, maps are an important source of information and allow to develop various human activities based on the data that they deliver.

   • About cartographic projections
     • Cartographic projections are representations of the spherical surface of the Earth in a plane, enabling the construction of a map. A map is the approximate representation of the earth's surface in a plane using geographic coordinates. This construction takes place through a flat system of parallels and meridians (represented by lines), that is, cartographic projections.
