General / Tiff orthophoto property

« on: October 11, 2012, 02:29:15 AM »

Hi,

I recently started using agisoft to process some aerial pictures. My input images are in the JPEG format, made up of three layers: RGB. When I come to export my orthophoto to a GeoTiff, the resulting file has 4 layers. Why it added a layer and how do I control that?
I want to do some image classification based on the RGB values of the orthophoto, therefore it is important to me to understand what these 4 layers means in respect to the 3 originals.
Thanks for the help.
