First of all, thanks for the example!

Just for the sake of understanding the whole class better, could you explain what the numbers, like 20037508.34 mean? Thanks!

Hi, the numbers refer to the conversions of the Mercator projection. For more information, see: https://en.wikipedia.org/wiki/Web_Mercator
