[gdal-dev] Nodata value and overviews

[Guy Doulberg]

Hi guys

I have a raster with NODATA value defined

I am creating overviews on top of that raster, using the gdaladdo

When using the overviews should I consider the NODATA value when reading
the pixels, or all pixels in the overviews are valid?

When calculating the overviews does gdaladdo consider the NODATA values as
invalid pixels?

Thanks, Guy
