In geography, latitude is a geographic coordinate that specifies the north–south position of a point on the Earth's surface. Latitude is an angle (defined below) which ranges from 0° at the Equator to 90° (North or South) at the poles. Lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude is used together with longitude to specify the.

The Equal Earth map projection is an equal-area pseudocylindrical projection for world maps, invented by Bojan Šavrič, Bernhard Jenny, and Tom Patterson in It is inspired by the widely used Robinson projection, but unlike the Robinson projection, retains the relative size of projection equations are simple to implement and fast to evaluate.

The Gall–Peters projection is a rectangular map projection that maps all areas such that they have the correct sizes relative to each other. Like any equal-area projection, it achieves this goal by distorting most projection is a particular example of the cylindrical equal-area projection with latitudes 45° north and south as the regions on the map that have no distortion.

The Peters Map of the World is an equal-area map. One square inch anywhere equals the same number of square miles. It presents the relative size of areas with complete accuracy. But what a different world this seems to be. This is a projection of the world that gives areas their true relative size/5(40).

The Peters Projection World Map is an equal area projection. That means that one square inch anywhere on the map is an equal number of square miles.

All the countries of the world are represented at true size and true proportion. This map is a edition and does not include updates like South Sudan/5(40). In Arno Peters, a German filmmaker, devised a map projection identical to Gall's orthographic projection and presented it in as a "new invention."He promoted it as a superior alternative to the Mercator projection, which was suited to navigation but also used commonly in world Mercator projection increasingly inflates the sizes of regions according to their distance from the.

newly constructed maps, of which “26 shew the mean monthly and annual temperature on hypsobathymetric maps, first on Gall’s projection, and second on north cir- cumpolar maps on equal surface projection; and 26 shew, for each month and for the year, mean pressure of atmosphere and the winds” also on Gall’s projection.

The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in It became the standard map projection for nautical purposes because of its ability to represent lines of constant course, known as rhumb lines or loxodromes, as straight segments that conserve the angles with the meridians.

The stereographic projection was known to Hipparchus, Ptolemy and probably earlier to the was originally known as the planisphere projection. [1] Planisphaerium by Ptolemy is the oldest surviving document that describes it.

One of its most important uses was the representation of celestial charts. [1] The term planisphere is still used to refer to such charts.

The Gall–Peters projection, named after James Gall and Arno Peters, is one specialization of a configurable equal-area map projection known as the equal-area cylindric or cylindrical equal-area achieved considerable notoriety in the late 20th century as the centerpiece of a controversy surrounding the political implications of map design.

The Mollweide projection is an equal-area, pseudocylindrical map projection generally used for global maps of the world or night sky. It is also known as the Babinet projection, homalographic projection, homolographic projection, and elliptical projection trades accuracy of angle and shape for accuracy of proportions in area, and as such is used where that property is needed.

The Peters Projection World Map is an equal area projection. That means that one square inch anywhere on the map is an equal number of square miles. All the countries of the world are represented at true size and true proportion. This is one of the few commercially available maps that is fair to all peoples/5(32).

This map-projection, invented by the French mathematician Postel in the sixteenth century, is frequently employed for star-maps, etc. — Equivalent map-projection, a map-projection which represents all equal surfaces on the spheroid by equal areas on the map.

Also called equal-surface map-projection. The Gall–Peters projection is a rectangular map projection that maps all areas such that they have the correct sizes relative to each other. Like any equal-area projection, it achieves this goal by distorting most shapes.

The projection is a particular example of the cylindrical equal-area projection with latitudes 45° north and south as the regions on the map that have no distortion.

About the book: This is the first volume (second Russian edition) of a course on general physics (the second, third and fourth volumes were published in (Molecular Physics), (Electricity and Magnetism) and (Optics) respectively; the fifth volume (Atomic Physics) is under preparation).

This book provides the theoretical background. With Fabry-Perot spectroscopy at Hα, we study the kinematics of ESO using velocity maps and position-velocity diagrams parallel to the major and to the minor axis of the galaxy.

We build the rotation curve of the disk and discuss the role of projection effects due to the fact of viewing this galaxy nearly edge-on. A map containing contours indicating lines of equal surface elevation (~), often referred to as topo maps.

The main function of the gallbladder is to store bile, also called gall, needed for the digestion of fats in ed by the liver, bile flows. The computed orthographic projection matrix is then multiplied by a scaling factor k, in order to guarantee that the real world extension corresponding to a pixel is the same, on average, for F i and O i.
