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.
