Thanks so much for the great content! Small correction: Please note that the maps labeled “North America” should be called “Continental United States”.

Over the period of time there is a buzz about Galls projection being better to represent the earth as compared to mercators …. I wish to hear your opinions about it . Also can you suggest hat kind of activities can I do with kids or assign them to know the differences better

Hello,
I’m fairly new to GIS as my background is from Software Development.
Does this mean a 3d map is better than a 2d map when developing a GIS application/

Thanks!

Earth is spherical or ellipsoidal having curves or curvature. Then why do we convert the 3d globe into planer co-ordinate system. Where as distance, shape and areas are already preserved on globe (that is itsoriginal shape). Distance measured incorporating the curvature of the earth will be accurate.

We know the Earth is Flat served on a plate. Why carry on the deception?
