Hey!

I'd like to read a ENVI file. It is a file array (1980*2100) and I'd like to some math about the pixel values.

What is the right way to import it and then use the data in IDL?

Thanks for suggestions!

Try

X = READ_BINARY(file, DATA_DIMS=[1980,2100], data_type = 2)

and change DATA_TYPE if needed

see
