Classification of RS data with Weka
By hariasa,
Hi all,
I was just wondering if someone has used WEKA (or RapidMiner) to classify RS data. Searching on the internet revealed some papers about people using it, but with only for very small areas.
Does anyone have experience with large amounts of data to classify with either of these programs? Since it seems kind of impossible to convert a large multi-band raster to the silly CSV/ARFF format WEKA uses.
Thanks
