Map Projections_Assignment_2
Projection 1
The Mercator projection
Distance: The only true scale is along the Equator, or along the longitudes instead.
Area: Is increasingly distorted toward the south of the Antarctic.
Shapes-are well represented, there are not distorted except the Antarctic regions.
Direction-scale is true in all directions.
Projection2
Baar equal area projection
Distance-is distorted, all the scales of this projection are not true.
Area-the areas produced on the map projection are inversely proportional to the area on the earth; this means that they are distorted.
Shapes- are distorted, many of the continents seemed twisted out of any semblance to reality. The earths shape is different from the original shape.
Directions-The angles of this projection are completely wrong (distorted).
Projection 3
The Mercator projection
Distances-are true onlyalong the equator.
Areas -the areas represented on the projection are proportional to their area on the earth.
Shapes-in this projection some of the continent wrenched out of normal shape, therefore they are distorted.
Directions-of this projection are true, especially the ones at the equator.
Projection 4
The Sinusoidal projection
Distance-scale is true only on the central meridian and the parallels. There is no distortion on the central meridian or the equator.
Areas-are distorted
Shapes-All shapes are distorted except in the middle,they are so badly formed.
Direction- angles of direction are designed inaccurately.
Projection 5
The Mollweide projection
Distance-Scale is true along latitudes. Distortion increases with distance from these lines and becomes severe at the edges of the projection.
Area-Lines of latitude are parallel to the equator. The distortion is greatest at the edges of the projection.
Shape-Shape is not distorted at the intersection of the center and latitudes. Distortion increases outward from these points and becomes severe at the edges of the projection.
Direction-angles are true only at the intersection of the center and latitudes. Direction is distorted elsewhere.
Projection 6
Azimuthal equal-area projection
Distances-measured from the center are true. Distortion of other properties increases away from the center point.
Shape-All shapes are distorted except at the center.
Area: Distortion increases outward.
Direction-the directions are true from the center outward.
Projection 7
Triangle equal area projection
Distance-measured distances are accurate.
Areas-are not distorted, the areas represented on the projection are the same as one represented on the original map.
Shape- is distorted except the ones in the middle.
Direction-angles of direction are portrayed accurately.
Projection 8
Bonne projection
Distances-scale is not preserved.
Area-The area is distorted
Shapes-Shapes on the center are not distorted, but eleswhere they are, and the overall shape of the world is complicated.
Directions- Scale is preserved only on the center of the projection.
Projection 9
Distance-the scale of the map rapidly becomes distorted as distance from the correctly represented standard parallel increases.
Area-the area is distorted, distortion increases mostly outwards.
Shapes-are distorted, the only shape that is not distorted is Australia because is at the center of the map.
Direction-the scale of this projection is inaccurately.
Projection 10
Distance-Distances for all aspects are accurate from the center point outward. The distances along the latitudes and longitudes are accurate.
Shape-All shapes are distorted except at the center, and increasingly from the center.
Area-Distortion increases outward from the center point.
Direction-True directions on this projection are observed from the center outward.
