Category talk:Map projections

Projections should not appear in both sub-cats and super-cats
The entries in sub-cats should not appear in the parent cat. That is the usual rule for categorization on Wikipedia. I will help fix this when I get the chance. Jason Quinn (talk) 08:29, 27 August 2010 (UTC)

Lacking information for lay-readers.
I've been looking at articles on several of the various projections, and most of the articles lack any explanation for lay-readers of the relative advantages and disadvantages of each. As a publication for the general public, it would behoove the writers, editors and others with expertise in these matters to add this information so that the rest of us can understand better what we're looking at. The geometric formulas are nice and all, but have no meaning to the general reader. I want to know in what way Mercator is accurate or inaccurate, and the same for the other projections. That information is lacking in many of the articles. 66.57.50.6 (talk) 15:12, 18 September 2015 (UTC)
