This issue is closed as the official tool has been updated and most "algebric notation" pages look to be updated to use "-0 notation." Page kept as history and explanation of the notations.


Graticule longitudes and latitudes are indexes that look like relative integers. They are the minimal value of all the points in the graticule if the values are positive, and they are the maximal value of all the points in the graticule if the values are negative.


So (-23.452365°,16.415222°) is located in the Graticule -23,16.

And (23.452365°,-16.415222°) is located in the Graticule 23,-16.


With this notation, 0 and -0 are different values (this rule will be called "-0 notation").


Issue with the Active Graticules's page

The "abs workaround" leads the Active Graticules's page into chaos. While most of the graticules use the "-0 notation" (example: Boston is refered as 42 -71), the United Kingdom mostly uses the "algebric notation" (example: Swindon is refered as 51 -2).

This inconsistency leads to wrong labels in the official tool.

This has been resolved -- I modified all the graticules + the active list. -- Phyzome 22:37, 27 May 2008 (UTC)
