Hello Agisoft community!
I have a quick and somewhat simple question.
I´ve been working with photogrammetry to quantify erosion on a certain beach. To do so I take aerial photography with a UAV and then generate dense point clouds with Agisoft Photoscan Pro. Due to the fact that I need really precise measurements I have been using GCP´s which I georeference using an RTK GPS to geotag our models. All tough the GCP´s are permanent marks that we placed along the coastline, and have been used in the monthly models to standardise them, some models have resulted with a low banana shape effect.
What might be causing this? I have been flying monthly since march using the same flight plan and geotag my models with the same GCP´s.
I´ve attached two images, one corresponding to march and the other to august so you can se the difference between them even after been georeferenced using the GCP´s.
Thanks in advanced
