Mapping between objects and dimensions

I began with a map of the world, a bmp file I found on the net. The coloration of the oceans was distracting for my purposes, so I darkened the oceans. To avoid getting lost in the C coding, I added some lines of text. The maps shown are 360x180 pixels, though I used, and will make available images twice that resolution.

The image of south pole below, demonstrates the utility of the added text.

The reader may rest assured that the author is aware of any and all errors and / or deficiencies in these images.
