Mercator Projection Uses

Although the Mercator projection is still used commonly for navigation due to its unique properties cartographers agree that it is not suited to general reference world maps due to its distortion of land area. It is a method by which the spherical globe of the Earth can be represented with errors on a flat map - which are required by atlases charts etc.

Why Maps Are Wrong Chalkdust

The following equations place the x -axis of the projection on the equator and the y -axis at longitude where.

Mercator projection uses. This method is useful for specific climatological maps and marine charts because it creates a display that offers features that are easier to read for the average person. As a result the Earths poles and landmasses closest to them are distorted. A sphere-based version of Mercator is used by several web mapping sites.

The Mercator projection mərˈkeɪtər is a cylindrical map projection presented by Flemish geographer and cartographer Gerardus Mercator in 1569. Nova et aucta orbis terrae description ad usum navigantium emendate et accomodata new and improved description of the world amended and intended for the use. Uses of Mercator Projection The Mercator projection is significant for navigation and almost every marine chart is based on it.

What is the future of. Mercator himself used the equal-area sinusoidal projection to show relative areas. Africa for example is depicted as smaller than North America when it is in reality three times larger.

While this style makes it easy to print onto maps and has largely become standardized it presents a distorted image of the Earth. Namely the Mercator projection minimizes non-European or American countries and continents while enlarging privileged world powers. The most famous of all map projectionsthe Mercatoris a cylindrical projection.

However the Web Mercator uses the spherical formulas at all scales whereas large-scale Mercator maps normally use the ellipsoidal form of the projection. Different cylindrical projections have been developed to preserve different spatial properties. Some preserve area some shape and some true distance along their meridians.

To keep longitude lines straight and maintain the 90 angle between the latitude and longitude lines the Mercator projection uses varying distances between latitude lines away from the equator. It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. This projection is widely used for navigation charts because any straight line on a Mercator projection map is a line of constant true bearing that enables a navigator to plot a straight-line course.

What projection does Google Maps use Epsg. The Mercator projection is a map projection that was widely used for navigation since loxodromes are straight lines although great circles are curved. It is less practical for world maps however because the scale is distorted.

It uses the same formulas as the standard Mercator as used for small-scale maps. Up until now Google Maps has used Mercator projection which projects the planet onto a flat surface. The spheres radius is equal to the WGS 1984 semimajor axis 63781370 meters.

Web Mercator is a slight variant of the Mercator projection one used primarily in Web-based mapping programs. While this style makes it easy to print onto maps and has largely become standardized it presents a distorted image of the Earth. This is why for uses other than marine navigation the Mercator projection is recommended for use in the Equatorial region only.

The Mercator projection was mainly used for maps. Originally created to display accurate compass bearings for sea travel an additional feature of this projection is that all local shapes are accurate and clearly defined. Street mapping services such as Google Maps Bing Maps MapQuest etc use a Mercator called Web Mercator for their map images.

What is a Mercator projection and what is its purpose. Areas farther away from the Equator appear disproportionately large. This is because within small.

This map projection is practical for nautical applications due to its ability to represent lines of constant course known as rhumb lines as straight segments that conserve the angles with the meridians. Despite these distortions the Mercator projection is generally regarded as being a conformal projection. It is also used for marine navigation since the lines of constant direction appear as straight lines on the map.

The Mercator projection was designed by its creator for shipboard use the title of the original map telling us as much. The Mercator projection is more accurate for areas closer to the equator and less accurate for area closer to poles. This made it possible for the entire globe to be drawn on a flat sheet.

Mercator projection is the display of a map of the world onto a cylinder in a way where all of the parallels of latitude have the same length as the equator. The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569. Up until now Google Maps has used Mercator projection which projects the planet onto a flat surface.
