<p class="MsoNormal">I have some DEMs that are created from lidar. For reasons related to seeing currents and wind effect, we did not ask for the water to be flattened, but rather it shows waves. This is cool, and what we wanted. BUT of course now we want
to create a second set of DEMs with a nice flat ocean.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have numerous pixels out in the ocean which are slightly less than 0. So how does one select out all pixels < 0 and substitute them with 0 with GDAL?
