Tie point coordinates accuracy
« on: February 05, 2021, 01:31:53 AM »
Hi everybody, I am new to the forum.

I have a question regarding tie points. My UAVs horizontal accuracy is +-1mt ( I would assume that the coordinates of the centre of each image have the same uncertainty). In the field I have set a grid of GCPs geolocated with an accuracy of 0.1mt. In my workflow in Metashape, I align the images and after I import my GCPs (text file) and I correct the position of the point cloud. I am interested into the position of tie points, so my question is: after the use of GCPs correction, can I assume an accuracy of the tie points coordinates of 0.1mt?
