Map projection examples. This is a summary of map projections that have articles of their own on wikipedia or that are otherwise notablebecause there is no limit to the number of possible map projections there can be no comprehensive list. The albers projection is an example of a conic map projection. The azimuthal map projection is angular given three points on a map a b and c the azimuth from point b to point c dictates the angle someone would have to look or travel in order to get to a.
These angular relationships are more commonly known as great. While equal area projections preserve area it distorts shape angles and cannot be conformal. Lets review some advantages and examples of using equal area projection maps.
Examples of equal area projection maps. As shown in the examples below equal area projection maps preserves the size of features true to their real area. Unlike conic projections the meridian is not constrained to be a straight line.
Examples of pseudoconic projections include bonne which is an equal area map projection. The maps are not constrained to rectangles or discs. Pseudoconic projection is one of the oldest map types and although they were used by ptolemy they are seldom seen today.
Map projections types and distortion patterns. The shape of the earth is represented as a sphere. It is also modeled more accurately as an oblate spheroid or an ellipsoida globe is a scaled down model of the earth.
Although they can represent size shape distance and directions of the earth features with reasonable accuracy globes are not practical or suitable for many applications. From aitoff to winkel these map projections are your blueprint to designing captivating cartographic masterpieces. Because its all about the audience lets map with authority and dig right into the big list of map projections.
Scroll down to see all 50 map projection examples. Which ones have you used in your maps. A map projection is a systematic transformation of the latitudes and longitudes of locations from the surface of a sphere or an ellipsoid into locations on a plane.
Maps cannot be created without map projections. All map projections necessarily distort the surface in some fashion. There is no limit to the number of possible map projections.
1 projections are a subject of several pure. One of the most famous map projections is the mercator created by a flemish cartographer and geographer geradus mercator in 1569. It became the standard map projection for nautical purposes because of its ability to represent lines of constant true direction.
Because there are so many different needs by map users there are projections that try to fit those needs as close as possible. Every map projection compromises some element eg distance in favor of other elements. Below are basic examples to show the main types of projections.
Amazing map projection explanation from 1921. This illustration from the book elements of map projection with applications to map and chart construction written in 1921 by charles h. Deetz born in 1864 and oscar s.
Adams born in 1874 is one of the best illustrations of the concept of map projections ever.
