Felix,<div><br></div><div>You can use Band.GetOverview to get a particular overview. For an example see:</div><div><a href="http://trac.osgeo.org/gdal/browser/trunk/gdal/swig/csharp/apps/GDALOverviews.cs">http://trac.osgeo.org/gdal/browser/trunk/gdal/swig/csharp/apps/GDALOverviews.cs</a></div>
<div><br></div><div>Drivers should anyway be able to select the most reasonable overview when reading data according to the requested extent.</div><div><br></div><div>Best regards,</div><div><br></div><div>Tamas</div><div>

Hello,<br>
<br>
if I wish to read data from a raster band that has additional overview bands, do I need to determine the appropriate band myself or is that internally handled?<br>
If I have to, is there some documentation on how to determine that?<br>
<br>
Thanks<br>
