I'm working right now only with Rio de janeiro(as i said earlier, some states have individual files with higher definition), and it has a size of about 58MB. I'm worried because it is one os the smallest states, and the lower definition file for the whole country is about 280MB. maybe i should break it in small parts before processing it(10x10 degrees maybe?)
anyway, how much time should i expect for these processes to take place with these file sizes?
