I have\r\n\r\n* Written a lot of documentation\r\n* Reworked the datum types, adding a new abstract `Datum` type.\r\n* Added a datum shift function, `datum_shift_ECEF`, which depends on the datum type\r\n* Added the Dawson et al. GDA94 <--> ITRF datum transformations\r\n\r\n\r\n---\r\nOriginal comment -\r\n\r\nStill a work in progress:\r\n\r\n* The tests suggest something's still wrong here, needs further testing.  Unfortunately I don't know of an easy source of good test data for this Australia wide.  Perhaps we can get some current station coordinates from ftp://ftp.ga.gov.au/geodesy-outgoing/gnss/solutions/final/weekly/ and compare to nominal GDA94 station coordinates.  May require some data munging.\r\n* Depends on CoordinateTransformations affine transformation branch\r\n\r\n@andyferris"},"comment":{"url":"https://api.github.com/repos/JuliaGeo/Geodesy.jl/issues/comments/237751390","html_url":"https://github.com/JuliaGeo/Geodesy.jl/pull/19#issuecomment-237751390","issue_url":"https://api.github.com/repos/JuliaGeo/Geodesy.jl/issues/19","id":237751390,"user":{"login":"andyferris","id":2974526,"avatar_url":"https://avatars.githubusercontent.com/u/2974526?v=3","gravatar_id":"","url":"https://api.github.com/users/andyferris","html_url":"https://github.com/andyferris","followers_url":"https://api.github.com/users/andyferris/followers","following_url":"https://api.github.com/users/andyferris/following{/other_user}","gists_url":"https://api.github.com/users/andyferris/gists{/gist_id}","starred_url":"https://api.github.com/users/andyferris/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/andyferris/subscriptions","organizations_url":"https://api.github.com/users/andyferris/orgs","repos_url":"https://api.github.com/users/andyferris/repos","events_url":"https://api.github.com/users/andyferris/events{/privacy}","received_events_url":"https://api.github.com/users/andyferris/received_events","type":"User","site_admin":false},"created_at":"2016-08-05T04:17:09Z","updated_at":"2016-08-05T04:17:09Z","body":"Great!\n\nSent from my iPhone\n\n> On 5 Aug 2016, at 2:07 PM, Chris Foster <notifications@github.com> wrote:\n> \n> @andyferris I think I sorted out the Ellipsoid pretty printing problem:\n> \n> julia> LLAfromECEF(GDA94())\n> LLAfromECEF(Ellipsoid(grs80))\n> \n> julia> LLAfromECEF(Ellipsoid(grs80))\n> LLAfromECEF(Ellipsoid(grs80))\n> —\n> You are receiving this because you were mentioned.\n> Reply to this email directly, view it on GitHub, or mute the thread.\n> \n"}}
