Question

What does RMSE represent in IMAGINE Photogrammetry?

Answer

RMSE, or Root Mean Square Error, is the distance between the input (source) location of a ground control point (GCP) and the retransformed location for the same GCP. It is a measure of “fit”, or how closely the retransformed location matches the desired output location of a point.
