Mauritania on five projections

Mauritania covers 1,056,023 km² of ground. Mercator draws it 1.14 times over. Area and shape readings on all five projections, each one measured.

On five projections

Each number is measured against its own projection's equator, not against another projection. These five rows do not share an axis - they are five answers to the same question: what did this map give up to lay this place flat?

ProjectionArea distortionShape distortion
Equirectangular1.071.07
Mercator1.141.00 constant
Natural Earth1.051.11
Equal Earth1.00 constant1.26
Gall-Peters1.00 constant1.76

Mercator inflates it most, 1.14 times over. Gall-Peters stretches it most: its long axis is 1.76 times its short one.

The same size, drawn otherwise

Nothing in the catalogue is close to Mauritania's area at a far enough latitude to be worth the comparison.

Bigger than the map admits

These cover more ground than Mauritania and Mercator draws them smaller anyway.

  • Colombia: Colombia is truly 1.10 times larger, and Mercator still draws this one 1.03 times bigger.
  • Ethiopia: Ethiopia is truly 1.08 times larger, and Mercator still draws this one 1.03 times bigger.
  • Bolivia: Bolivia is truly 1.03 times larger, and Mercator still draws this one 1.01 times bigger.

On an equal-area projection this section is empty, for every object there is. An equal-area map draws in proportion to true area, so it cannot draw a larger thing smaller. That is a definition, not a coincidence.
