pipeline functionality is currently documented by comments in PJ_pipeline.c and PJ_obs_api.c, and by the demo code in examles/pj_obs_api_test.c\r\n\r\nThat is somewhat limited.\r\n\r\n@kbevers suggests in a review of PR #453 that:\r\n\r\n> The pipeline concept is very powerful, but also rather complicated compared to what has been possible in PROJ.4 up until now. This needs to be documented thoroughly. I suggest a new section on the webpage, \"Coordinate transformation\" where the concept of pipelines can be introduced. It will also be a nice place to document the geodetic transformations that are coming from you soon. Additionally the new proj.h/pj_obs_api.c API should be documented in the \"Development\" section. This doesn't have to be a part of this PR, but should be written at least before the next release and preferably a lot sooner so first-movers has a chance to try things out.\r\n\r\nWhich is clearly the way to go.\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/OSGeo/proj.4/issues/comments/335264245","html_url":"https://github.com/OSGeo/proj.4/issues/454#issuecomment-335264245","issue_url":"https://api.github.com/repos/OSGeo/proj.4/issues/454","id":335264245,"user":{"login":"busstoptaktik","id":5608365,"avatar_url":"https://avatars3.githubusercontent.com/u/5608365?v=4","gravatar_id":"","url":"https://api.github.com/users/busstoptaktik","html_url":"https://github.com/busstoptaktik","followers_url":"https://api.github.com/users/busstoptaktik/followers","following_url":"https://api.github.com/users/busstoptaktik/following{/other_user}","gists_url":"https://api.github.com/users/busstoptaktik/gists{/gist_id}","starred_url":"https://api.github.com/users/busstoptaktik/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/busstoptaktik/subscriptions","organizations_url":"https://api.github.com/users/busstoptaktik/orgs","repos_url":"https://api.github.com/users/busstoptaktik/repos","events_url":"https://api.github.com/users/busstoptaktik/events{/privacy}","received_events_url":"https://api.github.com/users/busstoptaktik/received_events","type":"User","site_admin":false},"created_at":"2017-10-09T19:35:33Z","updated_at":"2017-10-09T19:35:33Z","author_association":"MEMBER","body":"Agree - you've done some amazing work on the documentation!"}}
