Pansharpened images are not properly stretched

[bogitamat]

Thanks for the good work and easy to use tool

I am facing a problem with pan sharpening. Pan sharpened images have reduced visual enhancement in comparison to images processed without --pansharp option (see http://tinypic.com/view.php?pic=ndsmcn&s=8#.Vd8fYmBHfuc , pan sharpened image on the left)

Would appreciate any help in the matter

P.S. I have the most up-to-date landsat-util on Mac Yosemite

I have the same issue, on Arch Linux and Ubuntu boxes:

This problem seems to be related to the pan sharpening calculations and the black 'nodata' around the image. When I use --clip as well as --pansharpen clipping the nodata, the color correction / histogram equalization works fine:

@gmaclennan Great observation. Thanks for spending time figuring this out. This should help me coming up with a fix.

Any update on this?

Just to follow up on this, the problem seems to be with color correction and nodata, even without pansharpening. Here is a comparison of the same area, the first created with

landsat process landsat8image.tar.bz --clip=...

and the second created without --clip and cropping afterwards.

@gmaclennan do you have the scene numbers of the examples you mentioned above?

[gmaclennan]

Yes, the first is LC80090612015251LGN00 and the second is LC82310592014267LGN00

Same problem. I am investigating on my end as well. Scene LC81050682014217LGN00 with -pansharen
