Kohonen created SOM for visualization, not regression or classification.
For classification he created LVQ and LVQ2. All three of Kohonen's algorithms are documented in the NN Toolbox.
For regression and classification the Multilayer Perceptron (NEWFF, NEWFIT and PATTERNNET) and Radial Basis Function (NEWRB) are, typically, superior.
After reading the documentation, try duplicating the demos and examples. Searching for relevant Newsgroup postings may also help.
Write back if you have further questions.
Hope this helps.
Greg

Thank you for your reply!
Could you please tell me which features should I extract from the satellite image to give as inputs to the LVQ or MLP network?
And please elaborate a little, if possible, on the feature extraction part..
