LocalWiki Antarctica, a crowdsourced map of the icy southern continent

LocalWiki's Philip Neustrom says,

My non-profit, LocalWiki, has been working on this really incredible
project to help document the continent of Antarctica. Most notable,
at least right now, is this custom map we've pieced together from
very-hard-to-find NASA aerial imagery and coastline datasets. It's
probably the most beautiful thing I've ever worked on.

Check out the LocalWiki for Antarctica. The project "aims to document the
full extent of human involvement on the continent," and for now is focused on a two-mile region
surrounding Palmer Station.
