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:
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?
