  • And what they look like in our map projection is arcs of circles that hit the boundary at right angles.

  • So that's kind of why the Mercator map projection is quite handy.

  • So this particular map projection is actually used for the polar regions because most of the other map projections don't work very well there.

  • It's a bunch of different map projections, all the different mathematical ways that we can show the world, which is a sphere on a flat plain.

  • The main graphic feature was a global surface temperature map animation time series from the 1880s to 2006, showing huge red areas spread across the top of the page, massively distorted by the map projection.

Morphology

map + projection

The meaning 'a method of depicting the curved surface of the Earth on a flat map' is directly compositional from 'map' (a chart of the Earth's surface) and 'projection' (the act of depicting a solid on a plane). This is a standard technical compound with clear semantics and cross-linguistic parallels, so a B1 learner who knows both constituents would very likely understand it.

Etymology

Map projection comes from the idea of taking the round Earth and 'projecting' it onto a flat sheet, like peeling an orange and trying to lay the skin flat. Because the skin must be stretched or cut, shapes and sizes change, so different map projections are different ways to show the globe on a flat map and explain why flat maps are never perfect.
