[Untitled][edit]

Suggested Change Last paragraph before image - "A GPS unit will commonly give a 10 digit grid reference, so in order to give a 6 figure reference from that you will have to ignore the 4th, 5th digits while using the 9th and 10th digits for rounding"

Should it not be ignore the 5th & 10th digit and use the 4th and 9th for rounding e.g. 1122366778 would become 112668

Yes this is correct: including your example would also help as this seems quite difficult to explain

Accuracy v. Precision: Should "accurate" in "With a standard system, the more digits one adds to a grid reference, the more accurate the reference becomes." be "precise"?SilasW 20:14, 2 May 2007 (UTC)[reply]

There is a surprising amount of overlap between these two articles, which come close to referencing each other, but don't. +mt 10:58, 30 June 2015 (UTC)[reply]

Why no north arrow on the map? 97.118.3.251 (talk) 12:58, 21 July 2019 (UTC) The map is intended to be similar to an extract from an Ordnance Survey map. Those maps do contain north arrows in the margin, but not within the body of the map itself. North is at the top.----Ehrenkater (talk) 13:03, 21 July 2019 (UTC)[reply]

Overhaul[edit]

The page looked like a mashup of grid reference encodings and projected coordinate systems, rather organized. I moved the page from Grid reference system to Projected coordinate system, the latter being the more common term in current use, and did a fair amount of editing and reorganizing, including adding a history section.
