[edit] Eccentricity Squared
The article lists eccentricity squared for NAD83 as 0.006694300229. NAD83 is based on GRS80, and this article states that its eccentricity squared is 0.00669438002290. It appears that the article is missing the 8 between "43" and "00"? But I wasn't sure if the source is accurate or if NAD83 is definitely the same as GRS80 so I didn't want to change it. -- – Zawersh 17:03, 28 May 2008 (UTC)
