Oops, sorry I meant a Spade, which is a scaled up Z3...to a coincidentally 70" wingspan.

Yikes that's quite the mark up or quite the great promotional offer.

Comment by Jakob Schmidt on October 8, 2015 at 11:48am

It's more of a scaled up Z3.

Is that a ritewing zephyr? I swear that is the exact design. I hope Chris at Ritewing is involved in that company, he designed an incredible airframe, those bays and choro design are his signature, i'd recognize it anywhere!

Thanks Shaun. That's what I was trying to do this morning, but it didn't seem very intuitive to me. I was in a hurry, though .I'll try again when I get back home.
Comment by Shaun Bell on September 17, 2015 at 2:08pm

Yes, but don't bother with more than 3.  Adding more questionable points isn't going to help.

I was just planning on using the GPS data from Google earth and adding it to the mosaic, if possible. Doesn't need to be super accurate, just enough to properly orient the results.

Do you just select a point in the raycloud and add the GPS data (7 times), and then re optimise?
Comment by Shaun Bell on September 17, 2015 at 12:42pm

How accurate?  If accuracy isn't that important, just take out a hand held gps and mark at lest three points you can see in the point cloud.  Then import those to GCP's.

2 pix4d questions - 

1. Is it possible to georeference a project after stitching, but still within Pix4d? I haven't seen any options other than adding GCPs in the raycloud editor and then re optimizing. Really, I'd just like to turn the ortho .tiff into a .geotiff.

2. The only option I see to export a shapefile is within the index calculator. When using RGB imagery, I don't see the option to export a shapefile without creating a false color map. Is this because the project I'm working in is not georeferenced?
