Hello

I am working on ortophoto.

First I aligned my images. After that I added my GCPs.

So what is next know?

Do I have to re-align after adding GCPs? or just continue dense cloud step?

We recommend to optimize camera alignment based on the GCP locations. Please check the corresponding step in our tutorials dedicated to Orthophoto/DEM generation: http://www.agisoft.ru/tutorials/photoscan/
