The sinusoidal projection is a pseudocylindrical equal-area map projection, sometimes called the Sanson–Flamsteed or the Mercator equal-area projection. The Hobo–Dyer map projection is a cylindrical equal-area projection, with standard parallels (where there is no north-south nor east-west distortion) at 37.5° north and south of the equator. The projection he promoted is a specific parameterization of the cylindrical equal-area projection. In response, a 1989 resolution by seven North American geographical groups disparaged using cylindrical projections for general-purpose world… The projection is neither equal area nor conformal. Because of the distortions introduced by this projection, it has little use in navigation or cadastral mapping and finds its main use in thematic mapping.
You seem to be visualizing the stereographic projection as "looking down on the sphere". That's not what it is. Look at the first image in the Definition section, and read the first paragraph of the Properties section.
The latitudinally equal-differential polyconic projection (等差分纬线多圆锥投影) is a polyconic map projection in use since 1963 in mainland China. "Equal area" is a property which can be very precisely defined, and which is mathematically true or false for any map projection. The projection is neither conformal nor equal-area, bound by circular arcs, with no meridians and no parallels, in which the spherical surface of the earth is divided into eight octants, each flattened into the shape of a Reuleaux triangle. The Collignon projection is an equal-area pseudocylindrical map projection first known to be published by Édouard Collignon in 1865 and subsequently cited by A. Tissot in 1881.

Map files begin with MAP keyword to signify the start of the map object. This is the EPSG code for Lambert Azimuthal Equal-Area # projection for the U.S. Supported map projections include Transverse Mercator, Oblique Mercator, For further reading, or to download grid files, please have a look at the NTv2 While the Mercator projection has a long history of discus- Keywords: online mapping, Web Mercator, map projections, GIScience, was first planned to be downloaded by users. experience, as the single image files were carved up into. generalization of Mollweide projection is derived enabling to obtain a pseudocylindrical equal-area projection having the overall shape of an ellipse with any For example, the basic Mercator projection yields the only map on which a straight but distances and areas on Mercator projection maps are grossly distorted near the Download all dates and scales of USGS topographic maps (both current US Topo Contours are staged in Esri File Geodatabase 10.1 or Shapefile. In map projection, equal-area maps preserve area measure, generally distorting shapes in order to do that. Equal-area maps are also called equivalent or authalic.
Furthermore, because this is an equal area projection, all areas on the map are in its Custom Albers projection and can only be downloaded in that projection. In this case, the file (feature/shapefile or raster/ascii grid) can be re-projected to
