What is a Lambert map projection? An Direction to a fixed location B (the bearing at the starting location A of the shortest route) corresponds to the direction on the map from A to B: Social Studies: Lesson Plans & Games Possible uses such as navigation, research, and general reference will require different projections. Equal-area maps are also called If the length of the line segment connecting two projected points on the plane is proportional to the geodesic (shortest surface) distance between the two unprojected points on the globe, then we say that distance has been preserved between those two points. 8th Grade Life Science: Enrichment Program The projections are termed cylindric or conic because they can be regarded as developed on a cylinder or a cone, as the case may be, but it is as well to dispense with picturing cylinders and cones, since they have given rise to much misunderstanding. What is a Map Scale? How is a planimetric map constructed? In case we want to draw a map of the world on paper, we need to exploit and apply a given projection that transforms the spherical earth into a flatten earth. What is a Mercator map projection? Map projections can be constructed to preserve some of these properties at the expense of others. What is a conformal map projection? p. 28American Cartographic Association's Committee on Map Projections, 1986.
Despite the name's literal meaning, projection is not limited to Most of this article assumes that the surface to be mapped is that of a sphere. All rights reserved. What does a map projection show? A map projection is a way of showing the globe on a piece of paper. - Definition, Types & Examples (1942). But the term A normal cylindrical projection is any projection in which The mapping of meridians to vertical lines can be visualized by imagining a cylinder whose axis coincides with the Earth's axis of rotation. The projections are described in terms of placing a gigantic surface in contact with the Earth, followed by an implied scaling operation. This requires a systematic transformation of the latitudes and longitudes of locations from the surface of the globe into locations on a plane. Middle Grades Social Science Group Counseling Strategies: Help & Review Purpose: the intended use of a map should be tied directly to its projection.
