Midterm - Projections

Question 1

point: equal area projection

Answer 1

area on map = area on globe

Question 2

preserve, distorts: equal area projection

Answer 2

preserves area, distorts shape

Question 3

examples: equal area projections

Answer 3

lambert cylindrical equal area projection, gall-peters projection

Question 4

point: lambert cylindrical equal-area projection

Answer 4

standard line on equator, central meridian at 0 degrees, spacing of parallels proportional to globe

Question 5

point: gall-peters projection

Answer 5

challenges distortions caused by popularity of mercator projection

Question 6

point: equidistant projections

Answer 6

distances from point are true to scale, parallels equally spaced along meridians, correctly shows distance from point of tangency

Question 7

preserve, distort: equidistant projection

Answer 7

preserves distance and direction from central point only, distorts shape

Question 8

point: conformal projections

Answer 8

scale is constant in all direction

Question 9

preserve, distort: conformal projections

Answer 9

preserves shape, distorts area

Question 10

example: conformal projection

Answer 10

mercator projection

Question 11

point: azimuthal projection

Answer 11

angles about a point are correctly represented, all directional relationships about pole are accurate, ALL others are distorted

Question 12

preserve, distort: compromise projection

Answer 12

preserves nothing, distorts everything, but minimizes it
