The maps below are showing the lines of equal altitude.
Using the equirectangular projection map the distortion (both shape and area) increases towards the poles.

(1) Summer solstice (June 21, declination +23.4°)

equal solar altitude elevation

(2) Winter solstice (December 22, declination -23.4°)

equal sun altitude zenith distance

(3) Equinox (March 21, September 23, declination 0°)

equal sun elevation
