The azimuthal projection provides navigators with an opportunity to find the minimum distance from one point to another. Hold a sheet of flat paper touching the map at one Gravity. All meridians are equally spaced and the scale is consistent along each parallel. Jean Cossin of Dieppe was one of the first to use the Sinusoidal, in a 1570's map. [2] In 1998 NGS abandoned the Robinson projection for that use in favor of the Winkel tripel projection, as the latter "reduces the distortion of land masses as they near the poles". Cylindrical map projections are rectangles, but are called cylindrical because they can be rolled up and their edges mapped in a tube, or cylinder. Poor directional map The poles are greatly distorted due to the odd shape of the map. paper touching the Earth at the equator, and represents the This blog highlights some light research on mapping projections conducted ahead of the Imperial Science Festival.

The only realy accurate representation of the spherical Earth is mid-latitude areas as well. Maps of smaller areas use what's known as a "conic" projection Robinson projection, while experienced cartographers ranked the Robinson and the Voxland Hyperelliptic map projections as their favorite. Pros--Accurate size and shape of Eastern and Western borders Cons--Poles are distorted by shape and size. How many times do a clock's hands overlap in a day? Although land-based calculations are available with close-range maps, it is particularly useful for long-distance travel from the sea or the air. Doctors' alarming details as Trump tries to project strength The projection is defined by the table:[7][8][9], The table is indexed by latitude at 5-degree intervals; intermediate values are calculated using interpolation. It was specifically created in an attempt to find a good compromise to the problem of readily showing the whole globe as a flat image.
