Orthographic projection in cartography has been used since antiquity. Like the stereographic projection and gnomonic projection, orthographic projection is a perspective projection in which the sphere is projected onto a tangent plane or secant plane. The point of perspective for the orthographic projection is at infinite distance.
Based on Ptolemy's 1st Projection Distances along meridians are conserved, as is distance along one or two standard parallels.

Albers: Two standard parallels with low distortion between them. c ...
This page provides conventions for the creation of orthographic maps. Orthographic maps display a country (or set of countries) on a globe representation of the world. Like location maps, orthographic maps are very basic, and should have very few, if any, labels. Maps should be centred on the subject of interest.
Orthographic projection (also orthogonal projection and analemma) [a] is a means of representing three-dimensional objects in two dimensions.Orthographic projection is a form of parallel projection in which all the projection lines are orthogonal to the projection plane, [2] resulting in every plane of the scene appearing in affine transformation on the viewing surface.
In cartography, a map projection is any of a broad set of transformations employed to represent the curved two-dimensional surface of a globe on a plane. [1] [2] [3] In a map projection, coordinates, often expressed as latitude and longitude, of locations from the surface of the globe are transformed to coordinates on a plane.
Popko notes the projection can be gnomonic too. [2] The two methods yield very similar results. Like Buckminster Fuller 's 1943 Dymaxion Projection , an octahedral butterfly map can show all the continents uninterrupted if its octants are divided at a suitable meridian (in this case 20°W) and are joined, for example, at the North Atlantic, as ...
Classification of Multiview orthographic projection and some 3D projections. First-angle projection: In this type of projection, the object is imagined to be in the first quadrant. Because the observer normally looks from the right side of the quadrant to obtain the front view, the objects will come in between the observer and the plane of ...
The Gall–Peters projection is a rectangular, equal-area map projection. Like all equal-area projections, it distorts most shapes. It is a cylindrical equal-area projection with latitudes 45° north and south as the regions on the map that have no distortion. The projection is named after James Gall and Arno Peters.
