I have a question concerning
I´m running windows 7 64b and am working from the OSGeo4W shell. I have multispectral images that need to be prepared for analysis but they are not saved in a single band per wavelength format. Instead each wavelength is saved in a tif 8b format and this needs to be converted to a 16b tif format with a single band. The data is stored in the green and blue bands and a formula is available to calculate the new band. Images are acquired with Tetracam Mini-MCA system and more details can be found here.
So my question is: how to use
gdal_calc to batch process images?
The only manual solution I found is separating the bands using
gdal_translate and repeating the calculations for each image separately.
