EO Browser GUI- measure tool

Afternoon all,
I was wondering if anyone would be able to point me in the right direction for any forum posts or documentation that might mention the error degree of the measurment tool on the EO Browser GUI
Kind regards

I do not believe this exists as this feature was not meant for scientific use.
I’d say the accuracy is limited with accuracy of the pointer in the GUI on the lower edge and on CRS distortions on the upper edge.
