What is transverse Orthomorphic projection?
The transverse Mercator projection, also known as the Gauss-Krüger projection, is similar to Mercator except that the cylinder touches the sphere or ellipsoid along a meridian instead of the equator. The result is a conformal projection that does not maintain true directions.
What does Mercator projection mean in geography?
Description. Mercator is a conformal cylindrical map projection that was originally created to display accurate compass bearings for sea travel. An additional feature of this projection is that all local shapes are accurate and correctly defined at infinitesimal scale. It was presented by Gerardus Mercator in 1569.
What is the purpose of a Mercator?
In 1569, Mercator published his epic world map. This map, with its Mercator projection, was designed to help sailors navigate around the globe. They could use latitude and longitude lines to plot a straight route. Mercator’s projection laid out the globe as a flattened version of a cylinder.
Where is a Mercator projection distorted?
Although the linear scale is equal in all directions around any point, thus preserving the angles and the shapes of small objects, the Mercator projection distorts the size of objects as the latitude increases from the equator to the poles, where the scale becomes infinite.
What did Mercator do?
His most famous work, the Mercator projection, is a geographical chart where the spherical globe is flattened into a two-dimensional map, with latitude and longitude lines drawn in a straight grid. Mercator’s view of the world is one that has endured through the centuries and still helps navigators today.
Which of the following is a characteristic of the Mercator projection?
Which of the following is a characteristic of the Mercator projection? The size and shape of countries in the higher latitudes are greatly exaggerated.
What is UTM projection good for?
This allows distances and angles to be computed easily, and minimizes distortion. While the military popularized the UTM projection for ground operations, it is also ideal for many GIS operations. The Mercator projection is conformal and preserves angles, but distortion increases away from the equator.
How does a Mercator projection work?
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. As a result, the Earth’s poles and landmasses closest to them are distorted.
What did Gerardus Mercator create?
What are the disadvantages of a Mercator projection?
Pros: Sailors loved it; preserves angles and directions in a small area.
How to project US states in transverse Mercator?
Transverse Mercator is a transverse cylindric projection. The central meridian and antimeridian lines are presented as one vertical line in the middle of the projection. Northern parts of meridians 90° away from the central meridian project as a horizontal straight line through the North Pole, extending to infinity when approaching the equator.
What are the main features of the Mercator projection?
The Mercator Map. The Mercator projection was developed in 1569 by Gerardus Mercator as a navigational tool.
Why is the Mercator projection so commonly used?
Length Deformation. That is,the length of longitude and latitude on the map is not exactly the same as that on the globe.
