What Is The Most Accurate Map Projection
Each projection preserves compromises or approximates basic metric properties. Because the curved earth s surface is not isometric to a plane preservation of shapes inevitably leads to a variable scale and consequently non proportional presentation of areas.
Which Is The Best Map Projection
Vice versa an area preserving projection can not be conformal resulting in shapes and bearings distorted in most places of the map.
What is the most accurate map projection
. In equidistant map projections accurate distances constant scale are maintained only between one or two points to every other point on the map. What s the best map projection. Some argue that the winkel tripel projection is the best projection see for example. It is named after james gall and arno peters.I m a graduated geography degree holder and i find it frustrating to continue to go into schools and see the mercator projection as the gold standard and possibly the oldest educational tool within that building that has gone without an update. Similarly if a projection is centered on a point distances to every other point from the center point remain accurate. He claims the above map called the authagraph world map achieves this task. Areas like greenland antarctica and africa are all distorted on traditional mercator maps because it s difficult if not impossible to replicate the globe in two dimensions.
Distances measured along these lines are proportional to the same distance measurement on the curved reference surface. I believe this is the most straight forward and in layperson s terms explanation of map projection that i ve read online to date. The mercator projection map is the most popular but it is also riddled with inaccuracies. The authagraph may look much different than other map projections and it is.
There is only perhaps the best map projection for whatever purpose one needs to draw a map. At its most basic you can. It is thought that the first use of the name gall peters was by. This is hands down the most accurate map projection in existence.
But hajime narukawa a keio university graduate student in tokyo. He called it a new invention that allowed poorer less powerful nations to be restored to their rightful proportions. In fact authagraph world map is so proportionally perfect it magically folds it into a three dimensional globe. There is no such thing as a most accurate map projection.
Different map projections have improved on one another but all have their pros and cons when it comes to sacrificing certain dimensions over others. Japanese architect hajime narukawa invented this projection in 1999 by equally dividing a spherical surface into 96 triangles. The projection first created in 1999 frames the world s physical components in a 2d rectangle attempting to represent their relative sizes as accurately as possible. This new map called the authagraph may be the most accurate map projection created to date.
Also in most projections there are one or more standard lines along which scale remains constant true scale. Map projections can be constructed to preserve some of these properties at the expense of others. It is indeed a good compromise between area and shape deformations. Another cyclindrical map projection regaining accuracy in surface area.
Whilst gall first described the projection in 1855 it was not until 1973 when peters began to heavily market the projection as the peters world map that it became popular.
