The projection then maps each area to a square map (the corresponding cube side).\r\n\r\nSuch a cube model is very well suited for planetary-scale terrain rendering, as it allows quadtree-based data management.\r\n\r\nA cube model can also use Gnomonic projection, but this introduces strong angle and area distortions. In contrast, QSC projection is an equal-area projection and at the same time introduces only limited angle distortions.\n\nMigrated-From: https://trac.osgeo.org/proj/ticket/179"},"comment":{"url":"https://api.github.com/repos/proj4-bot/proj.4/issues/comments/104553049","html_url":"https://github.com/proj4-bot/proj.4/issues/179#issuecomment-104553049","issue_url":"https://api.github.com/repos/proj4-bot/proj.4/issues/179","id":104553049,"user":{"login":"proj4-bot","id":12542084,"avatar_url":"https://avatars.githubusercontent.com/u/12542084?v=3","gravatar_id":"","url":"https://api.github.com/users/proj4-bot","html_url":"https://github.com/proj4-bot","followers_url":"https://api.github.com/users/proj4-bot/followers","following_url":"https://api.github.com/users/proj4-bot/following{/other_user}","gists_url":"https://api.github.com/users/proj4-bot/gists{/gist_id}","starred_url":"https://api.github.com/users/proj4-bot/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/proj4-bot/subscriptions","organizations_url":"https://api.github.com/users/proj4-bot/orgs","repos_url":"https://api.github.com/users/proj4-bot/repos","events_url":"https://api.github.com/users/proj4-bot/events{/privacy}","received_events_url":"https://api.github.com/users/proj4-bot/received_events","type":"User","site_admin":false},"created_at":"2015-05-22T07:40:23Z","updated_at":"2015-05-22T07:40:23Z","body":"**Comment by warmerdam on 6 Dec 2013 20:47 UTC**\nThe documentation looks great.  I have rerun autogen.sh so I think this is now complete and it should appear in the 4.9 final release.\r\n"}}
