I have generated C3 matrix from RADARSAT-2 Quad-pol data. After applying Refined Lee filter I wanted to perform Supervised Wishart Classification. I did Supervised Classification Training and got text file (.txt) with cluster centre value in each element of T3 matrix for all classes. Then, I moved to Supervised Wishar Classification window. As Source Product I chose C3 filtered data. As Training Data Set I chose that text file generated in Supervised Classification Training step.
I got the following SNAP error:
“A problem occurred during the target product initialisation
Message: Supervised-Wishart_classification: C:/Users/…/TC.txt” (the path to text file generated in Supervised Classification Training step.
I saved also whole details report if it’s needed to solve the problem.
I have also been trying to apply the supervised Wishart classification on quad-pol RADARSAT-2 data and I get the same issue.
It seems that a number of users have been reporting this issue and this seems like a bug in the software. One could use PolSARpro although it is not a very user friendly tool and I would like to have this functionality performed with SNAP. Therefore I would like to know from the developers if this issue is being dealt with?
I did the same steps, except for the subset and the vector data. But i didn’t receive any error. I think this tool doesn’t allow for the integration of training data. Supervised in this context just means that a scatterinc type is assigned according to the Wishart chart.
