Graphics
editI've added a top-level graphic and a local graphic pertaining to the example given in the article. Color may be an issue for the local graphic. Hm. mdf 18:34, 19 December 2005 (UTC)
They're great, thanks for doing that! The only thing I would suggest is to highlight the PJ square in the GJ map, in line with the example. — Johantheghost 19:02, 19 December 2005 (UTC)
- Made GJPJ darker. mdf 18:14, 20 December 2005 (UTC)
North Pole
editCould someone with the knowledge please add some words on how the north pole is normally expressed in the GEOREF system? Is it NNAA00000000, NMAR00000000 or NMAQ00006000? Or do you have to be content with NMAQ00005999 being "close enough"? — Preceding unsigned comment added by 90.227.119.137 (talk) 14:40, 20 March 2013 (UTC)
Requested move 15 December 2016
edit- The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review. No further edits should be made to this section.
The result of the move request was: Moved to World Geographic Reference System. There is no consensus for moving GeoRef to GeoRef (database), it needs separate RM discussion. (non-admin closure) Fuortu (talk) 11:15, 24 December 2016 (UTC)
Georef → GEOREF – The proper name is GEOREF, as used by all primary references in the article. +mt 00:40, 15 December 2016 (UTC)
- Move to World geographic reference system per WP:NATURALDIS. I weak support the move as proposed since it meets MOS:TM since it's an acronym, but there's innate confusion between the proposed move location and GeoRef. Steel1943 (talk) 06:51, 15 December 2016 (UTC)
- Move to World geographic reference system as per WP:NATURALDIS (with Georef (graphic coordinate system) as redirect); and move GeoRef to GeoRef (database). In ictu oculi (talk) 22:00, 15 December 2016 (UTC)
- Comment: all primary sources use title case "World Geographic Reference System", so this title is perhaps more appropriate. (I'm thinking of similar articles like World Geodetic System that use title case). +mt 23:02, 15 December 2016 (UTC)

Format conversion error
editThe format conversions from DD° MM' SS" to decimal degrees, DD.ddddddd°, appears to be incorrectly calculated
38° 17' 10" = 38 + (17+10/60)/60 = 38.28611111°
-76° -24' -42" = -76 - (24 + 42/60)/60 = -76.41166667°
The resulting one minute resolution GEOREF represenation should be GJPJ3517 The minute component of latitude, 17, can be read right off the original representation, the exact number of minutes. Minute component of longitude is 59 - floor(24 + 42/60) = 35. This error makes it difficult for people (like me) trying to implement this to have confidence in our results.
1.00 Minute precision: GJPJ3517
0.10 Minute precision: GJPJ353171
0.01 Minute precision: GJPJ35301716
