Is it possible to get RMSE of georeferenced image?

[klem]

Hi,

I'm reviewing the following example:

https://developers.arcgis.com/javascript/latest/sample-code/layers-medialayer-control-points/

and was wondering - is it possible to return RMSE (Root Mean Square Error) of georeferenced image? I did check methods and properties of ImageElement and MediaLayer but it seems nothing in there.

Hi @klem,

With media layer we are using a perspective transformation with 4 control points to place the image and the RMSE would be zero.  There isn't any rubber sheeting of the image and each of the four image pixels are placed exactly where specified.
