Map A map is the conventional representation of the earth or a part of it ,as seen from above. Map projection: It is the system of transformation of the spherical surface onto a plane surface. It is carried out by an orderly and systematic representation of the parallels of latitude and the meridians of longitude of the spherical earth or part of it on a plane surface on a conveniently chosen scale

Properties of projections: Preservation of area Preservation of shape Preservation of scale Preservation of bearing Ease of drawing

Types of projection Equal area or homolographic projections Equidistant projections Orthomorphic projections True bearing or azimuthal projections
