<div dir="ltr">Ah, yes I see what you mean. Photoscan, as far as I know, only does this because you have a 3D model that you can orient and basically declare your Z axis, which is a clever approach. That means that Photoscan actually gives you an orthophoto.<div><br></div><div>Hugin is just stitching and blending, as I understand it. I know Alex Mandel and Michelle Tobias have a lot of experience with Hugin... . No point in ODM recreating that functionality, I think (though willing to be proven wrong) although plenty of reason to integrate that wonderful multiscalar blending algorithm... .</div><div><br></div><div>Cheers,</div><div>Best,</div><div>Steve</div><div><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Mar 25, 2015 at 10:30 AM, Rimvydas <span dir="ltr"><<a href="mailto:naktinis@gmail.com" target="_blank">naktinis@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">OK, I get what you mean.

<p dir="ltr">What georeferencing info adds is knowledge of where the Z axis is. Without that knowledge, AFAIK, there's no real way to create an ortho from the mesh.</p>
