[edit]Identify map projection in NASA eclipse atlas
[edit]![](http://upload.wikimedia.org/wikipedia/commons/thumb/4/43/Central_eclipses_2001-2020.png/220px-Central_eclipses_2001-2020.png)
Can anyone tell
- What map projection is used in this image (original at http://eclipse.gsfc.nasa.gov/SEatlas/SEatlas.html ), and
- What the latitude of the top edge of the map is?

- It looks like a Miller projection, and the mapping from y pixel coordinate to latitude is , putting the top and bottom at about ±85°. -- BenRG (talk) 18:31, 25 March 2015 (UTC)
