I would like to crop rectangular fragments of given size and for these purposes I need coordinates, which covers all Earth and measured in meters.

I wrote the following picture:

enter image description here

Latitude and longiture are in radians.

I mapped all surface into leaf-like 2D shape.

x coordinate is a distance in meters from zero meridian along parallel.

y coordiante is a distance in meters from equator along meridian.

What is the name of this projection?

  • Note that this projection won't conserve arbitrary distances, so your question title might be somewhat misleading.
