What is the advantage of an interrupted projection?
The flat map is heavily interrupted in order to preserve shapes and sizes.
Advantages: It has less distortion of relative size of areas, most notably when compared to the Mercator projection; and less distortion of shapes of areas, notably when compared to the Gall–Peters projection.
What does interrupted projection mean?
Interrupted projections are those in which the northern and/or southern hemispheres are divided into a number of lobes. This is done in order to minimize the distortion of the major land masses.
What is wrong with the Mercator projection?
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.
What is the Mercator projection best used for?
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 are the pros and cons of using a Mercator map projection?
MercatorPros: Sailors loved it; preserves angles and directions in a small area.Cons: Bad for understanding the real size and shape of continents and countries.Related: After this video you’ll never trust a map again.Pros: The only ‘area-correct’ map of its time; got featured in The West Wing (S2E16)More items…•
What are the characteristics of an interrupted projection map?
The Goode homolosine projection (or interrupted Goode homolosine projection) is a pseudocylindrical, equal-area, composite map projection used for world maps. Normally it is presented with multiple interruptions. Its equal-area property makes it useful for presenting spatial distribution of phenomena.
What are the 4 types of distortion?
There are four basic characteristics of a map that are distorted to some degree, depending on the map projection used. These characteristics include distance, direction, shape, and area.
What is wrong with the Robinson projection?
The Robinson projection is neither conformal nor equal-area. It generally distorts shapes, areas, distances, directions, and angles. The distortion patterns are similar to common compromise pseudocylindrical projections. Area distortion grows with latitude and does not change with longitude.
What are the advantages and disadvantages of a Mercator projection?
Advantage: The Mercator map projection shows the correct shapes of the continents and directions accurately. Disadvantage: The Mercator map projection does not show true distances or sizes of continents, especially near the north and south poles.
What does Pseudocylindrical mean?
Pseudocylindrical definitions (cartography) Representing the central meridian and each parallel as a single straight line segment, but not the other meridians. adjective.
What does the Goode Homolosine projection distortion?
Distortion. Goode homolosine is an equal-area (equivalent) projection. Shapes, directions, angles, and distances are generally distorted. The scale along all parallels in the sinusoidal part, between 40°44’12” north and south, and along the central meridians of the projection is accurate.
What is an interrupted projection give an example of one?
An interrupted projection cuts and flatten the earth like an orange peel. It remains in one piece, but the image is “interrupted” with gaps or cuts. An example of an interrupted projections is Goode’s projection.
What is the Robinson?
The Robinson projection is a map projection of a world map which shows the entire world at once. It was specifically created in an attempt to find a good compromise to the problem of readily showing the whole globe as a flat image.
Why does every map have distortion?
Flattening the Earth Likewise with the Earth—if we want to make a map, we need to distort the Earth’s surface to flatten it. … We have many different map projections because each has different patterns of distortion—there is more than one way to flatten an orange peel.
What do all map projections have in common?
Certain map projections, or ways of displaying the Earth in the most accurate ways by scale, are more well-known and used than other kinds. Three of these common types of map projections are cylindrical, conic, and azimuthal.
