The result was keep. No arguments for deletion aside from the nominator. The issue of merging, redirecting, renaming, or what have you can be discussed on the article's talk page. (non-admin closure) Ron Ritzman (talk) 00:34, 12 June 2010 (UTC)[reply]
Long standing unreferenced tag and a search did not produce anything to support the material. The term itself seems to be notable but as a coordinate system for hyperbolic space unrelated to the "Quadrant model" mentioned in the article. A search on "Quadrant model"+hyberbolic returned 0 hits. I also found a source that uses the term for coordinates that use hyperbolic functions in the same way that polar coordinates use trigonometric functions. These are unrelated to the material in the article. This has a large number of articles that link to it because it's included in a template for orthogonal coordinate (incorrect since the system in the article is not orthogonal).
