Definition of mercator-projection noun in oxford advanced learner's dictionary meaning, pronunciation, picture, example sentences, grammar, usage notes, synonyms and more. A method of making maps in which the earth's surface is shown with the meridians as parallel straight lines spaced at equal intervals and the parallels of latitude as parallel straight lines intersecting the meridians at right angles but spaced farther apart as their distance from the equator increases: on such maps the area of a. Mercator projection, type of map projection introduced in 1569 by gerardus mercator it is often described as a cylindrical projection, but it must be derived mathematically the meridians are equally spaced, parallel vertical lines, and the parallels of latitude are parallel, horizontal straight lines, spaced farther and farther. Oblique mercator projection¶ the oblique aspect of the mercator projection the projection centerline, instead of being a latitude (as in the regular mercator projection) or a longitude (as in the transverse mercator projection) can be an arbitrary great circle (defined by specifying two points) from mpl_toolkits basemap import. Mercator projection definition: an orthomorphic map projection on which parallels and meridians form a rectangular grid | meaning, pronunciation, translations and examples.
Dictionary definition of mercator projection a map projection of the earth onto a cylinder areas appear greater the farther they are from the equator similar words: mercator's projection. Define mercator projection: a conformal map projection of which the meridians are usually drawn parallel to each other and the parallels of latitude. Mnemonicdictionarycom - meaning of mercator projection and a memory aid ( called mnemonic) to retain that meaning for long time in our memory.

A map projection of the earth onto a cylinder areas appear greater the farther they are from the equator. The universal transverse mercator (utm) system applies the transverse mercator projection to mapping the world, using 60 pre-defined standard zones to supply parameters utm zones are six degrees wide each zone exists in a north and south variant the universal polar stereographic projection is used in the utm. It is particularly useful when mapping regions of large lateral extent in an oblique direction both parallels and meridians are complex curves the projection was developed in the early 1900s by several workers several parameters must be provided to define the projection gmt offers three different definitions: option - joa.
Because the earth is roughly spherical, every flat map distorts our planet one way or another the most popular version is the mercator projection, created by flemish cartographer gerardus mercator in 1569 it's been widely used for centuries, including today in various forms by google maps and many. 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 (constant true direction means.
42 web mercator is a map projection commonly implemented in commercial and open source data sets and internet based visualization applications web mercator mathematics are formulated on a spherical assumption of the earth which conflict with the defined wgs 84 ellipsoid reference system.
