WebBoth have extreme distortion far from the equator and cannot show the poles. However, they are different projections and have different properties. Distortion of sizes ... Although the surface of Earth is best modelled by an oblate ellipsoid of revolution, for small scale maps the ellipsoid is approximated by a sphere of radius a, ... WebScale Factor at Central Meridian is the ratio of map scale along the central meridian and the scale at a standard meridian, where scale distortion is zero. Finally, some projections, including the Lambert Conic Conformal, include parameters by which you can specify one or two standard lines along which there is no scale distortion.
WebScale can also distort features on a map. areas are shown (a small scale map) the potential for distortion is great.

WebAccording to scale : 1. Large scale maps : These maps represent small area of the earth on a large size of paper sheet with greater details. Examples: Cadastral maps, topographical maps. 2. Small scale maps : These maps represent large areas on a small sheet of paper. They have fewer details. Examples are Atlas and Wall maps. great wall on lake harbin rd in morrow gaWebSmall scale maps have large scale variations in a conformal projection, so recent world maps use other projections.

Distances along the Equator are always correct, but nowhere else on the map. Between about 15° north and south the areas and shapes are well preserved. Further out (to about 50° north and south) the areas and shapes are reasonably well preserved. florida hospital west florida divisionWebBoth the media and the geosciences often use small-scale world maps for demonstrating global phenomena. The most important demands on the projection of these maps are: (1) the map distortions have to be reduced as much as possible; (2) the outline shape of the mapped Earth must remind the viewer of the Globe. florida hospital winter garden florida
