I will say that JAG3D might not be the best option, Mike James' software SFM_Georef is a much more robust way to georeference SFM data.<br /><br />As to your question about 'documents or publications of the JAG3D transformation?' - I don't, I used the software for one project a while back and haven't really used it since.James Dietrichhttps://www.blogger.com/profile/03611662238915453239noreply@blogger.comtag:blogger.com,1999:blog-908258308186667628.post-79945017287892140282015-02-10T14:24:39.282-08:002015-02-10T14:24:39.282-08:00Hi James,

The results in "Transformation" contains the transferred coordinates of the SfM points and the corresponding errors for Y, X, H. Can I treat these errors as the errors of SfM reconstructed point cloud?<br /><br />Also, do you have some documents or publications of the JAG3D transformation?<br /><br />Kind regards,<br />Zhihua XuAnonymoushttps://www.blogger.com/profile/12185520636384604088noreply@blogger.comtag:blogger.com,1999:blog-908258308186667628.post-62484711672152345982012-07-31T10:34:50.552-07:002012-07-31T10:34:50.552-07:00Hello James,

Basically, its look totally different from the old version which both you and Mark Willis at blog Markaeology used in your tutorials.<br /><br />I thought the easiest solution would be to find the older version, which I cannot find so far, so I was wondering if you still had a copy, and if yes, could you ftp me a copy? I would really appreciate the help,<br /><br />thanks,<br />nicole<br />---<br />Nicole,<br /><br />I looked around online and couldn't find the older versions either. I uploaded a zipped copy of version 3.3.20110211 to my Dropbox, I'll leave it up for a couple days.<br /><br />Good Luck, JamesJames Dietrichhttps://www.blogger.com/profile/03611662238915453239noreply@blogger.comtag:blogger.com,1999:blog-908258308186667628.post-76882327910554204612012-07-28T20:21:26.464-07:002012-07-28T20:21:26.464-07:00This comment has been removed by a blog administrator.Unknownhttps://www.blogger.com/profile/16742136452195793145noreply@blogger.com
