Hello all- I have a question related to encoding. I'm using a seperate program which takes either 16 bit or 8 bit (flat binary files) as inputs (they are raster satellite imagery and the associated quality files), but can't handle both at the same time. Problem is the quality and the image come in different formats (quality- 8bit, image- 16bit). I need to switch the encoding on the
I think some more detail about these files is necessary. What do these 16/8 bit quantities represent? Are these files just a sequence of such quantities, or is there meta information (i.e. image dimension)?
quality files to 16 bit, without altering anything else (they are img files right now). I imagine this is a fairly simply process, but I haven't been
Does 'img files' indicate that these files are formatted according to a standard?. Finally, are you using some R code to manipulate these files? Have an example, including data?
able to find a package or anything which can tell me how to do it- perhaps I'm searching the wrong terms, but I did look. Is there any methods to do this quickly? Ideally, the solution would involve reading in a list of files and replacing the original with the new, 16 bit version, as I have over 300 files to convert. I hope that's clear. Thanks in advance!
