A map projection is a systematic transformation of the latitudes and longitudes of locations from the surface of a sphere or an ellipsoid into locations on a plane. The Three Main Families of Map Projections. Unwrapping the Sphere to a Plane. Cylindrical Projections. Conic Projections. Azimuthal Projections. Unwrapping the Sphere. Some cylindrical projections are defined by a geometric process based on perspective. It can roughly be imagined as a semitransparent spherical shell wrapped by a. The mercator map projection is one of the most well known cylindrical map projections.
Selected Map Projections Cylindrical Projections. Cylindrical Equal Area; Cylindrical Equal-Area projections have straight meridians and parallels, the. Types of Map Projections January 5 Cylindrical map projections are great for comparing latitudes to each other and are useful for teaching and visualizing. A cylindrical projection can be imagined in its simplest form as a cylinder that has been wrapped around a globe at the equator. The points on the spherical grid are. A cylindrical projection is a type of map in which a cylinder is wrapped around a sphere (the globe), and the details of the globe are projected onto the cylindrical.
A map projection is used to portray all or part of. Cylindrical—Mathematically projected on. Aspect—Individual azimuthal map projections are divided.

Pseudocylindrical Map Projections. All cylindrical projections fill a rectangular plane. Pseudocylindrical projection outlines tend to be barrel-shaped rather than. In reality cylindrical map projections are not so simply constructed. The three aspects of the cylindrical projections: Tangent or secant to equator is termed regular. Projection Images Type Properties Creator Year Notes; Equirectangular = equidistant cylindrical = rectangular = la carte parallélogrammatique: Cylindrical. If the width of equatorial cylindrical maps is normalized by rescaling, then (since their spacing of meridians is identical) a projection's only defining feature is.
