<p class="MsoNormal"><span style="font-family:"Arial",sans-serif"> We are working on a project with Geo-spatial images using python language for our development purpose. To visualize the images properly pyramid layer is necessary. GDAL buildoverview functionality
of python, we are using to generate the overview but it is utilizing only the CPU. We are able to generate the pyramid layer using other python library utilizing the GPU but not able to add this pyramid layer into the geospatial images of
<strong><span style="font-family:"Arial",sans-serif">".tiff"</span></strong> file format as overview layer. <o:p></o:p></span></p>
