Mapping

1. Projective projections

   • They are classified based on the figure on the which the sphere is projected, those that use the plane or those that are developed through a geometric figure (cone or cylinder).

2. Cartographic Projection

   • It is a mathematical transformation of the curved surface of the earth (three-dimensional) on a flat surface (two-dimensional).
     • Classification of projections
       • The representation of the earth's surface on a flat surface, without deformations, is geometrically impossible.
         • According to the deformation of the sphere in the plane. (Metrics)
         • According to the method to project the sphere. (Projectives)
         • Modified

3. Classification of Cartography

   • Basic cartography
     • It is the most important and most important cartography necessary from which they can other maps derived from it can be obtained.
   • Thematic cartography
     • Set of cartographic activities aimed at showing the structural characteristics of a certain geographical distribution.

4. Coordinate systems

   • Parallels
     • They are imaginary lines drawn on the surface terrestrial, horizontally, are written in degrees (°), minutes (´) and seconds («)
   • Set of values that allow unequivocally identify the position of a point in space.
   • Geographical coordinates
     • The geographic coordinate system is a system of spherical coordinates by which a point is locate with two angular values:. latitude and longitude.
   • Coordinate
     • It is a pair or set of numbers that are used to find a distance from a specific place.
   • Meridians
     • They are imaginary lines drawn on the earth surface vertically

5. Universal Transverse Projection Mercator (UTM).

   • The UTM projection is one of the best known and used.
   • This is a projection transverse cylindrical

6. Basic concepts

   • Mapping
     • It is the graphic representation of elements spatial, captured on a plane, using a projection system and a relationship provided between the terrain and a map.
   • Geodesics
     • Geodesy is the science that studies the shape and dimensions of the Earth. The data obtained from geodetic and topographic studies are used to create accurate maps and plans.
   • Map
     • Maps are descriptions, or information documents graphics, which distinguishes them from any other type of description, written, verbal or otherwise

7. Cartography was born due to the man's need to locate with respect to its environment
