    EPSG Method for This is the spherical form of the projection. See coordinate operation method Lambert Cylindrical Equal Area (code ) for ellipsoidal form. Differences of several tens of metres result from comparison of the two methods. The first projected map is a Mercator, which is a conformal map (we will look at the Mercator in greater detail later). Notice that the BASIC shape of the head is held true, but the area is severely distorted. In the second instance of projection, an equal area map is shown.

    So-called equal-area projections maintain correct proportions in the sizes of areas on the globe and corresponding areas on the projected grid (allowing for differences in scale, of course). Notice that the shapes of the ellipses in the Cylindrical Equal Area projection above are distorted, but the areas each one occupies are equivalent. The map's purpose narrows your choices, but doesn't determine a projection. After all, there are many conformal projections, many equal-area projections, and many compromise projections. The next step in choosing a projection is to decide on the class of projection: cylindrical, conic, or azimuthal.

In cartography, the cylindrical equal-area projection is a family of cylindrical, equal-area map projections. The term "normal cylindrical projection" is used to refer to any projection in which meridians are mapped to equally spaced vertical lines and circles of. In cartography, a map projection is a way to flatten a globe's surface into a plane in order to make a map.

This requires a systematic transformation of the latitudes and longitudes of locations from the surface of the globe into locations on a plane. All projections of a sphere on a plane necessarily distort the surface in some way and to some extent. Lambert first described this equal area projection in It has been used infrequently.

Projection method. A normal perspective projection onto a cylinder tangent at the equator. Points of intersection. The equator. Linear graticules. In the normal, or equatorial aspect, all meridians and parallels are perpendicular straight lines. Conical Projection Two Standard Parallel | दो मानक अक्षांश शंकु प्रक्षेप की रचना #ConicalProjection - Duration: Rainbow7 31, The Equal Area Cylindrical projection, or Lambert Cylindrical projection, or Lambert cylindrical equal-area projection, is a map projection based on a cylinder that is most suitable for world maps where area distortion must be kept to a minimum.

Devised by Johann Heinrich Lambert init is the fourth of seven projections invented by him. A series of modifications were proposed by Gall in. In cartography, the Lambert cylindrical equal-area projection, or Lambert cylindrical projection, is a cylindrical equal-area projection is undistorted along the equator, which is its standard parallel, but distortion increases rapidly towards the any cylindrical projection, it stretches parallels increasingly away from the equator.

equal-area map projection: 1 n a map projection in which quadrilaterals formed by meridians and parallels have an area on the map proportional to their area on the globe Synonyms: equal-area projection Types: homolosine projection an equal-area projection map of the globe; oceans are distorted in order to minimize the distortion of the.

The most popular map projection in the world has been around for years now. It was created by Flemish cartographer Gerardus Mercator in – a time when Antarctica hadn’t even been discovered.

Mercator was designed as a navigational tool for sailors as it was most convenient to hand-plot courses with parallel rules and triangles on this map. A cylindrical projection can be imagined in its simplest form as a cylinder that has been wrapped around a globe at the equator.

If the graticule of latitude and longitude are projected onto the cylinder and the cylinder unwrapped, then a grid-like pattern of straight lines of latitude and longitude would result.

The Equal Earth map projection is a new equal-area pseudocylindrical projection for world maps. It looks similar to the widely used Robinson projection, but unlike the Robinson projection, retains. An equal-area projection purposely centered on Africa in an at A projection that maintains overall shapes and relative positi a map projection in which a region of the earth is projected o.

The form of this projection tangent at the Equator is often called the Lambert Equal-Area Cylindrical projection.

That and other special forms of this projection are included separately in this guide, including the Gall Orthographic, the Behrmann Cylindrical, the Balthasart Cylindrical, and the Trystan Edwards Cylindrical projections. A projection developed to accommodate scanning of satellite devices.

Essentially it is a conformal projection, but is different from the Transverse Mercator in that the central line of the projection is the satellite groundtrack, along which distortion is minimized.

A type of cylindrical projection called a Mercator projection shows direction well. It was long used to make charts that sailors could use to find their way around the globe.

Like all cylindrical projections, a Mercator projection greatly distorts the size of land near the poles. In a Mercator projection, Greenland and Africa are about the same.

What is an Equal Area Projection? An equal area projection is a map projection that shows regions that are the same size on the Earth the same size on the map but may distort the shape, angle, and/or scale.

The Cylindrical Equal Area projection uses a normal perspective projection onto a cylinder tangent at the equator. Cylindrical Equal Area. Description. Lambert first described this equal area projection in List of supported map projections.Every map projection compromises some element (e.g., distance), in favor of other elements.
