Taking it at face value, green means go. Red means stop. White could mean neutral.

On a flat earth with an ice rim Antarctica, I've been mulling over the possibility that the actual distance between McMurdo and Rothera-- in effect-- the Marie Byrdland coast-- is where the compression mapping might take place. In other words, the distances and times are going to make sense in the green and white zones-- but the red zone is where distances will NOT make sense. I don't know what mathematics would be used to simulata lines of longitude and latitude to make that happen-- especially with airliners and ships running all over the place needing accurate information so I'm not proposing that this is the case. However, seeing the red zone causes me to reconsider that original thought. Here is my best flat earth map of Antarctica so far so the reader can compare the red and green zones above with the ice rim version.
Note that the area between Rothera and McMurdo has ONE station Russkaya that apparently no longer exists as a full station although a few references have been made to it in some reports. This stretch is, even as First Officer Felix notes, devoid of stations for the most part. The area between McMurdo around to Mawson is the green zone-- approximately where I have GREEN ARROWS above from a previous idea. From Mawson around to Rothera, is the white neurtral zone which I don't know how to interpret.
INSPECTIONS
Just one more thought on inspections. If mere sailboats can race around Antarctica at 45 to 60, then how difficult would it be for fully equipped military/scientific inspection ships to go around Antarctica for a "full and complete inspection" of all stations on the coast of Antarctica? It should not be very hard. Yet there was no inspection since the winter of 2012-2013 according to ATS reports.

LATEST ATS REPORT HAS NO PHOTOS
I find it amusing that the latest report is 260 pages with no pictures or diagrams or maps. How is that possible?
