What is an oval shaped projection map?
The Ortelius oval projection is a map projection used for world maps largely in the late 16th and early 17th century. It is neither conformal nor equal-area but instead offers a compromise presentation.
What are the 4 types of map projections?
What Are The 4 Main Types Of Map projections
- Azimuthal projection.
- Conic projection.
- Cylindrical projection.
- Conventional projection or Mathematical projection.
What type of map is Mercator?
cylindrical map projection The Mercator projection (/mərˈkeɪtər/) is a cylindrical map projection presented by Flemish geographer and cartographer Gerardus Mercator in 1569.
What are the 5 different types of map projections?
Types of cylindrical map projections you may know include the popular Mercator projection, Cassini, Gauss-Kruger, Miller, Behrmann, Hobo-Dyer, and Gall-Peters.
Why is CMB oval shaped?
The CMB is shaped like an oval for the same reason that many maps of the world are ovals. You can't take a sphere and make it flat without tearing it, because a sphere is fatter in the middle than at the top and bottom.
What is conic map projection?
In map: Map projections. Conic projections are derived from a projection of the globe on a cone drawn with the point above either the North or South Pole and tangent to the Earth at some standard or selected parallel.
What is Mercator projection used for?
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.
What is a cylindrical map?
( sə-lĭn′drĭ-kəl ) A map projection in which the surface features of a globe are depicted as if projected onto a cylinder typically positioned with the globe centered horizontally inside the cylinder.
What is the main difference between Mercator and UTM projection?
The transverse Mercator map projection is an adaptation of the standard Mercator projection which flips the cylinder 90 degrees (transverse). The UTM projection flattens the sphere 60 times by shifting the cylinder central meridian 6° for each zone. This gives cartographers a map to work with always in meters.
What is a Mollweide projection map?
The Mollweide projection is an equal-area pseudocylindrical map projection displaying the world in a form of an ellipse with axes in a 2:1 ratio. It is also known as Babinet, elliptical, homolographic, or homalographic projection. The projection is appropriate for thematic and other world maps requiring accurate areas.
Why is the CMB so important?
The CMB is useful to scientists because it helps us learn how the early universe was formed. It is at a uniform temperature with only small fluctuations visible with precise telescopes.
What does a cylindrical projection show?
cylindrical projection, in cartography, any of numerous map projections of the terrestrial sphere on the surface of a cylinder that is then unrolled as a plane. Originally, this and other map projections were achieved by a systematic method of drawing the Earth's meridians and latitudes on the flat surface.
What is the difference between the Mercator and Peters Projection?
In addition, Mercator only distorts longitudinal distances (except very close to the poles), whereas Peters screws up the scale almost everywhere for both longitude and latitude. This is why Mercator beats out Peters in the world of cartography, and why Google Maps uses a modified Mercator projection.
What is a conic map projection?
Conic projections are created by setting a cone over a globe and projecting light from the center of the globe onto the cone. Ptolemy's maps used many conic projection characteristics, but there is little evidence that he actually applied the cone or even referred to a cone as a developable map projection surface.
What is a UTM map?
UTM is the acronym for Universal Transverse Mercator, a plane coordinate grid system named for the map projection on which it is based (Transverse Mercator). The UTM system consists of 60 zones, each 6-degrees of longitude in width.
What is UTM projection used for?
The Universal Transverse Mercator (UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth. Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth as a perfect ellipsoid.
What is a Pseudocylindrical projection?
Pseudocylindrical projections for world maps are characterized by straight hori- zontal lines for parallels of latitude and (usually) equally-spaced curved meridians of longitude. They are therefore related to cylindrical projections in which meridians are straight instead of curved.
What is a Goodes map?
Goode homolosine is an equal-area pseudocylindrical projection for world maps. It is most commonly used in interrupted form. It is a combination of Mollweide (or homolographic) and sinusoidal projections, hence the name homolosine.
What are COBE WMAP and Planck?
COBE had four (only three were useful), and WMAP had five. COBE could measure temperature fluctuations that were approximately 70 microkelvin (µK) in magnitude; Planck can get down to precisions of around ~5 µK or better.
What temperature is CMB?
2.725 Kelvin The actual temperature of the cosmic microwave background is 2.725 Kelvin. The middle image pair show the same map displayed in a scale such that blue corresponds to 2.721 Kelvin and red is 2.729 Kelvin.
What is a better map than Mercator?
It replaces the traditional Mercator map style that many of us are familiar with. The Gall-Peters map. Strebe / Wikimedia Commons The Mercator was designed in 1569 by cartographer Gerardus Mercator.
What is Conic map projection?
In map: Map projections. Conic projections are derived from a projection of the globe on a cone drawn with the point above either the North or South Pole and tangent to the Earth at some standard or selected parallel.
What is the difference between WGS and UTM?
The difference is that WGS 84 is a geographic coordinate system, and UTM is a projected coordinate system. Geographic coordinate systems are based on a spheroid and utilize angular units (degrees).
Is UTM a Mercator projection?
UTM is the acronym for Universal Transverse Mercator, a plane coordinate grid system named for the map projection on which it is based (Transverse Mercator). The UTM system consists of 60 zones, each 6-degrees of longitude in width.
What is aw map?
Advanced Warfare – Multiplayer Maps. Here are all the Advanced Warfare multiplayer maps for the Xbox 360, PlayStation 3, Xbox One, PlayStation 4 and PC. There are a total of 13 maps in the game, plus one bonus map called Atlas Gorge.

Why is the map of the CMB an oval?
The CMB is shaped like an oval for the same reason that many maps of the world are ovals. You can't take a sphere and make it flat without tearing it, because a sphere is fatter in the middle than at the top and bottom. To see why this is true, peel an orange and try to flatten it.
Which map projection has no distortion?
a globe Distortions. The only 'projection' which has all features with no distortion is a globe. 1° x 1° latitude and longitude is almost a square, while the same 'block' near the poles is almost a triangle.
Is WGS84 an ellipsoid?
WGS84 consists of a reference ellipsoid, a standard coordinate system, altitude data, and a geoid. The error of WGS84 is believed to be less than 2 centimeters to the center mass.
Is UTM geographic or projected?
About UTM. The Universal Transverse Mercator (UTM) system is a commonly used projected coordinate reference system. UTM subdivides the globe into zones, numbered 0-60 (equivalent to longitude) and regions (north and south).
