A registry allows you to use an authName+ID. All CRS defns should specify "order, units, and representation." For 19127, they haven't approved any authority yet, if I remember correctly. | |

And as to ISO 6709:2008 deferral to the CRS definition for grid/planar values--does it make any mention of which standards or sources? EPSG, NATO/USDOD (UTM/UPS), NGS/NOAA for U.S. State Plane? Or is it just the generic "order specified in the CRS definition"? | |

Add information from ISO 6709:2008

| Feb 11, 2011 at 21:17 | comment | added | mkennedy | @Dan, oh, I agree completely, but the movement had taken place, and ended up getting revised to the current latitude, THEN longitude. On x,y: unfortunately, not everyone equates x = easting, y = northing! Esri has several enhancement requests to support changing the labels for axes, swapping order, etc. | |
| Feb 11, 2011 at 21:13 | comment | added | mkennedy | @Stuart, unfortunately I don't have access to the 2008 revision, and don't fancy paying 122 euros for the privilege! Someone here might have it; I'll see if I can find a copy. There's still copyright issues on how much I can post. | |
| Feb 11, 2011 at 17:48 | comment | added | V Stuart Foote | Melita -- you are spot-on that ISO 6709 IS the standard. But the ISO 6709:2008 revision "...additionally specifies representation of horizontal point location using coordinate types other than latitude and longitude." Could you please expand on those aspects of the standard for folks. | |
| Feb 11, 2011 at 1:31 | comment | added | user681 | That doesn't mean that the standard is the best. My students get confused with the mix of lat/long...then you introduce easting and northing...then x/y. I would favour that one stick with the mathematical representation of coordinates, whether spherical or planar, x/y, easting/northing, long/lat...perhaps a movement could be afoot | |
