Manual Accuracy Assessment Report this article as Inappropriate to us !!!Login to Reply

I have a set of accuracy data (400 pts)  that consists of a table with two columns.  One column represents the reference and the other the mapped value as shown below.  Does anyone know of a way to cross tabulate this data to get an error (confusion) matrix?  At this point I am considering doing it manually, but it seems like there should be a tool or database process that can accomplish this?

 

Any advice would be greatly appreciated!

You may try looking at this article from the University of Alaska.  Hope it helps.
