Hello I want to create an overlay for google maps. As far as I know google maps using Spherical Mercator, so the system where I read the maps use Mercator but is not specified which (spherical or cylinder) type it use.
When i create the images, i get some information in common. That means I have an offset. I want to try to solve this using cylinder mercator coordinates, but i don't know how can i transform google coordinates to Cylinder Mercator coordinates.
Thank you in advance.
