<p class="MsoNormal">Hi<o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I would like to read in QGIS or GDAL an interpolated value in a DSM (well, actually it is a geoid model, but it is the same behaviour). See that I do not want the pixel value, but the linear interpolation among the neighbour pixels, assuming
that the pixel value is in the center of the pixel.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">For instance, this file<o:p></o:p></p>

</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Is there any way to get it (without implementing the interpolation myself)?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">If I understood correctly gdallocationinfo is not interpolating, just giving the pixel value.<o:p></o:p></p>
