Hi.
I have two CC datasets:
1. structured aerial dataset
2. orbit dataset
What is the best workflow to merge the datasets:
1. Merge ATs and then re-submit AT?
2. Merge before AT (photogroup blocks), then submit AT?
I have created Tie Points with the same name in both datasets (blue crossed in screenshots above). When I try either method 1 or 2 above, the tie points are duplicated (i.e. Tie Point 1 and Tie Point 1 (2)).
Result of merging via Method 1 (orbit dataset and tie points sit below structured dataset and tie points):
Result of merging via Method 2 (you can see the duplicated tie point crossed above/below each other):
Best would be to use fake or surveyed control points to merge them after each block is aerotriangulated. This dataset is not correct you had to do zoom-by-feet from higher to lower altitude. What I mean to go from higher to lower altitude by spiraling down to point of interest(POI). See our example where the monument is captured from ground in high resolution and matched with photos from altitude by spinning down to the the monument and all in one multi-resolution model.http://realitymodels.northeurope.cloudapp.azure.com/rm/Burtnieku_baznica_kopskats_3mx/App/index.html
When you say fake points do you mean tie points or control points. I presume the latter, so I would extract the xyz from one of the productions or AT and then add these fake control points to the other AT and then merge the ATs. I will give this a go.
Control points. You just read points from one model and mark them in other so they are in one coordinate system ready for merging.

Using fake GCPs worked well. Thanks Oto
Oto, what are you using to host your 3D model? Loads well.
