Q. What type of map is best suited for maritime navigation Weegy?
Mercator projection
Q. Is Mercator map accurate?
Mercator maps distort the shape and relative size of continents, particularly near the poles. This is why Greenland appears to be similar in size to all of South America on Mercator maps, when in fact South America is more than eight times larger than Greenland.
Q. Why do we still use the Mercator map?
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.
Q. What are the disadvantages of the Mercator projection?
Disadvantages: Mercator projection distorts the size of objects as the latitude increases from the Equator to the poles, where the scale becomes infinite. So, for example, Greenland and Antarctica appear much larger relative to land masses near the equator than they actually are.
Q. What is one advantage of a Mercator projection?
Advantages of Mercator’s projection: – preserves angles and therefore also shapes of small objects – close to the equator, the distortion of lengths and areas is insignificant – a straight line on the map corresponds with a constant compass direction, it is possible to sail and fly using a constant azimuth – simple …
Q. What are the strengths of the Robinson projection?
The Robinson projection is unique. Its primary purpose is to create visually appealing maps of the entire world. It is a compromise projection; it does not eliminate any type of distortion, but it keeps the levels of all types of distortion relatively low over most of the map.
Q. What map projection does National Geographic use?
Winkel tripel projection
Q. What is the main purpose of using map projections?
A map projection is one of many methods used to represent the 3-dimensional surface of the earth or other round body on a 2-dimensional plane in cartography (mapmaking). This process is typically, but not necessarily, a mathematical procedure (some methods are graphically based).
Q. What are the 3 planes of projection?
[FIGURE 3-2] Projections of the point are made onto three of the surfaces that make up the box: the top or “H” (horizontal) plane, the front or “F” (frontal) plane, and the right side or “P” (profile) plane.
Q. What is called projection?
When you push something away from a central structure, that’s called projection. Both the ject in projection and the word jet come from the Latin root jactus, which means “throw.” A jet plane throws itself — or projects itself — away from a central structure (the Earth) and into the air.
Q. What is first angle projection?
First angle projection is a method of creating a 2D drawing of a 3D object. It is mainly used in Europe and Asia and has not been officially used in Australia for many years. In Australia, third angle projection is the preferred method of orthographic projection.
Q. What is 1st 2nd and 3rd angle projection?
To get the first angle projection, the object is placed in the first quadrant meaning it’s placed between the plane of projection and the observer. For the third angle projection, the object is placed below and behind the viewing planes meaning the plane of projection is between the observer and the object.
Q. What is the symbol of Third Angle Projection?
When view are drawn in their relative position Top view comes above Front view, Right side view drawn to the right side of elevation. A Third Angle Projection drawing is identified by the third angle projection symbol. The angle of projection symbol typically appears in angle of projection block near to Title block.
