Add/remove photos after GCP points all done?

[rossnixon]

I have 38 aerial photos in my project.
I have located and marked GCPs on all the photos.

I should have checked the photo quality earlier, and now want to remove 4 photos and replace them with some spare photos. Can I do this without re-observing all my GSPs?

Hello rossnixon,

You can remove some photos from the project and add new ones, then you can specify the projections of existing markers on those photos using Place Marker option in the Photo view mode.

However, please note that photos added to already aligned image set wouldn't contain any tie points, so you'll need to run the Align Photos operation for the complete set again.
