Most likely it'll have to be artificially corrected. The terrain data is very accurate, but some of the locations have lower resolution thresholds than others (Antarctica being one of them ... just take a look at the USGS website to see where some of the data is limited). Best bet now is any time you find a section like this, bring up the HUD (tab key) and take a screenshot, so that Cameni and AngryPig can be aware of it on their todo list. I think eventually they might have something released to allow the end user to correct the issue, and submit the fix, but that's probably still a ways away.
