Greetings
I’m a ORFEO TOolbox user and I realized, through a few messages from Antonio and Hamish, that GRASS has an addon module, called i.pr, that performs a few classification methodologies.
The i.pr.training uses a interactive (based on Xterminals) and a non-interactive based on (citing Description)
The second option for generating the training sample file can be done non-interactively. This is done by specifying a GRASS sites file. This file should represent the locations of training samples and ought to have been previously generated either by digitising (v.digit) or else by v.in.ascii. Features will be extracted for these locations in a similar fashion as previously described. The class will be assigned to the examples based on the information stored in the sites file.
What is a GRASS sites file? How can I obtain this?
Thanks
best regards,
Luisa
