Talk:Geographic coordinate conversion

message: What are the ranges of degrees, minutes and seconds that are allowed to use? And also what are the allowed number systems for the numbers? What do you think about these values:
23° -45' 22.1"
-23° -45' -22.1"
-(23° 45' 22.1")
23° 61' 61"
23° 45.7' 22.1"

message: This article pretends, that the world has only WGS84-coordinates. That's not true, there are others like Gauss-Krüger coordinate system, so the name of the article or the article should be changed. --141.52.232.84 (talk) 09:22, 8 October 2008 (UTC)
thread_title:  WGS84-centric 

message: With this article slated for deletion and all the good howto information exported to Wikiversity, I decided to completely rewrite the article. The conversion between degrees-minutes-seconds and decimal degrees has been condensed into a short section, while all the other types of conversions of geographic coordinates, such as conversions among datums, has been added. It is still incomplete in many places (e.g., the datum conversion methods could be filled out with more formulas and application examples), but is hopefully a good start on this notable subject based on reliable sources. --Mark viking (talk) 22:16, 5 March 2014 (UTC)
thread_title:  Complete rewrite 

message: Someone added a tag proposing a merge with Geographic coordinate system.  I merged material on overlapping topics, but decided most of what's here is technical and probably uninteresting to readers of the other article.  Also, much of what's here applies to geographic datum and I think merging all three articles would probably make the result too long.  So, I'm leaving this article as a standalone, and noting in the intro that readers are expected to be familiar with the content of the other two articles (since I removed the context from this article for the sake of not repeating ourselves). -- Beland (talk) 09:42, 29 July 2015 (UTC)
replies: text: Your approach makes good sense to me. There is a lot of detail here that would not be interesting to someone just wanting to learn a little more about geographic coordinates and how to read maps. Thanks, --Mark viking (talk) 17:46, 29 July 2015 (UTC)

thread_title:  External links modified (January 2018) 

message: I am the creator of the site convertecef.com, which aims to help people make accurate conversations between ECEF and geodetic coordinates (in particular, we've found people make mistakes with the altitude term, causing unexpected or incorrect answers to be displayed).  The site is free to use, though it does have a premium API option.  By my understanding, as the creator of the site it would be a conflict of interest to post the link directly in this article even if relevant.  If another editor were willing to try it out and see if they think it is a worthwhile addition to the article I'd appreciate it.  Otherwise any feedback would be welcome.
Thank you for your consideration.

message: In ENU to ECEF and in ECEF to ENU formulas, the ENU coordinates have been named x,y,z. I think that use of E,N,U letters would be more clear.
