<p>SPOT 6/7 satellite imagery is captured with a dynamic range of 12 bits per pixel per channel (<a href="https://eos.com/spot-6-and-7/">ref</a>). However almost all of the SPOT imagery I have seen in use has been 8 bits per channel, and split into RGB natural
colour (Bands-321) and Near-infrared-RG false colour (Bands-432). What information is lost in this 12 to 8 bits conversion?<o:p></o:p></p>
<p>I'm wondering if we should be altering our request for purchase specifications to deliver the full bit depth.<o:p></o:p></p>
<p><em>Although I'm referencing SPOT imagery specifically the question is general and really applies to any satellite or sensor system.</em><o:p></o:p></p>
