Answer:
(1) What is a Mercator map?
Answer: 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.
(2) What is a Robinson map?
Answer: 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.
(3) What is a polar map?
Answer: A map projection designed so that a straight line from the central point on the map to any other point gives the accurate distance between the two points.
(4) What is a Albers map?
Answer: The Albers equal-area conic projection, or Albers projection (named after Heinrich C. Albers), is a conic, equal area map projection that uses two standard parallels. Although scale and shape are not preserved, distortion is minimal between the standard parallels.
