The map shows a relief map of an area. The relief maps are characterized by having contour lines that are a representation system composed of different shapes or lines that represent cutting planes of the surface depending on their height, these are characterized by keeping distance between them, and depending on this it can know if the terrain has a more or less steep incline. Also, contour lines allow us to recognize where the peak of a mountain is since this being the highest part is represented by a circle or undefined shape that represents the last contour of the plane.
