<p class="MsoNormal"><span style="color:#1F497D">Hi Grant,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The NoDATA values, if not specified are calculated from the source rasters. For RGB imagery, this typically is either 0 or 255, unless you are using an alpha band.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">You can though remove the NoDATA tag from the raster. I know of two of ways to do this.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="color:#1F497D"><span style="mso-list:Ignore">1.<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]><span style="color:#1F497D">Use gdal_edit with the –unsetnodata, which will modify the existing dataset.<o:p></o:p></span></p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="color:#1F497D"><span style="mso-list:Ignore">2.<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]><span style="color:#1F497D">Use gdal_translate to copy the raster but by using the –a_nodata and setting it to none, to remove the NoDATA tag<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I would suggest if using the first one, that you make a backup of the raster, just in case.<o:p></o:p></span></p>
