&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;==Calculations==&lt;br /&gt;
The equirectangular projection size: &amp;#039;&amp;#039;&amp;#039;14268x7135&amp;#039;&amp;#039;&amp;#039; which equals to ~100MPix but since it&amp;#039;s a projection the real pixels are stretched - they only look close to the real ones when on the virtual sphere. At the same time the equator of the projection consists of real pixels since they are projected as they are along the equator.&lt;br /&gt;
&amp;lt;font size=&amp;#039;2&amp;#039;&amp;gt;&lt;br /&gt;
 L = 2*pi*R (1)&lt;br /&gt;
 S(sphere) = 4*pi*R^2 (2)&lt;br /&gt;
 (1)=&amp;gt;(2) S(sphere) = L^2/pi = 14268^2/3.14 ~ &amp;#039;&amp;#039;&amp;#039;64.8MPix&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
