The etymology of the term comes from the Greek choros , which means: ” country” and graphia , which means: “description”. It refers to the representations of the city made in the same way that an artist paints from life. Chorography, unlike cartography that is more abstract, eases the understanding of the represented cities. Initially, chorography had a purely literary character as it was referred to those textual descriptions of the territory included in the Laudes Civitatum of the first century A.D. During the Renaissance the term acquired a wider meaning to be understood also as a graphical urban representation.

Abstract
The great advances in the field of computer graphic design, have led to the development of more powerful applications, which have become an essential tool for the designer and have revolutionized the teaching of Descriptive Geometry. However, design software is not perfect, as there are some limitations that have to be overcome. This chapter focuses on solving the problem of obtaining oblique perspectives from a 3D model, as it is a common trouble in most of CAD software, since they only provide orthogonal projections and perspectives from a 3D model. This obstacle has led to the fact that the use of oblique projections, such as military and cavalier perspectives, has been drastically reduced.
