GEOL 101 Lecture Notes - Lecture 2: Mercator Projection, Centimorgan, Conformal Map
Document Summary
Fraction which means the denominator is small and show a small portion of earth in detail: small scale maps have a small rep. Equivalence- the correct size ratio of area on the map to the corresponding actual area. Conformality - proper angular relationships are maintained across the entire map: the main problem with conformality maps is that the size of an area must be considerably distorted to depict the proper shape. The paper positioned this way creates a tangent to the globe at the equator (circle of tangency) and becomes standard parallel of projection: the mercator (famous) is a conformal map projection designed to facilitate oceanic navigation. Sphere is undevelopable and the globe is the only true scale model of the earth ( Projections: an orderly system of parallels and meridians used as a basis for. All parallels are parallel and are evenly spaced. Parallels and meridians cross at right angles. Conformal projection: rectangular and shows are in correct shape.
