I am realitively new to RC and especially when it comes to geo location. I get photos from different people and I do not have coordinates and sometimes do not know the camera that they took the photos from. I have been trying to read tutorials on GCPs, but it says that I need to upload the GCP coordinates. I was not given coordinates by people who sent me the photos… how am I able to get coordinates then so photos can be georefereced? I was thinking of going into photoshop and marking areas, but then how can I make accurate coordiante .txt files for them manually (if I have their long/lat coordinates from google and altitude from a dimension they took on site) ?
Please let me know how to do this, I am very new to the coordinate aspect but have to unfortuantely work in this way with a team. I really appreciate the help!
