<p class="MsoNormal">Hi Folks,<o:p></o:p></p>
<p><code><span style="font-size:10.0pt">gdal_translate</span></code> has the option
<a href="https://gdal.org/programs/gdal_translate.html#cmdoption-gdal_translate-exponent">
<code><span style="font-size:10.0pt;color:blue">-exponent <exp_val></span></code></a> to use in conjunction with
<code><span style="font-size:10.0pt">-scale</span></code> that will<o:p></o:p></p>
<p style="margin-left:36.0pt"><i>apply non-linear scaling with a power function. exp_val is the exponent of the power function (must be positive).<o:p></o:p></i></p>
<p>This describes what the function does at the mechanical level but not why or when it might be a good idea. What are appropriate scenarios to use this feature? How is it useful and what does it accomplish?<o:p></o:p></p>
