Using fmask with Landsat 8 scenes #9

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Landsat 8 channels are slightly different than Landsat 7:

Looks like you have to change fmask significally to make it work with Landsat 
8, will you support it?

Or maybe you will improve algorithm for even better results (2 new channels 
were added in Landsat 8).

Oh, i just have found that nasa will add Quality Assessment (QA) band with 
cloud layers. Wonder which algorithm are they using for detecting cloud (ACCA 
or fmask?).

Yes, we shall make benefit of the new bands (especially the cirrus band) to 
make Fmask work better for the new data and we are hoping the Fmask results can 
go into QA band for the USGS products.

Do you have an idea of a release date for a Landsat-8 compatible version? Is it 
to be expected this summer?

This website title is "Automated clouds, cloud shadows, and snow masking for 
Landsat 4, 5, 7, and 8 images", with Landsat 8 images included,
Does this mean you have upgraded the code to include Landsat 8?

I have run the Windows Standalone version of FMask for Landsat 8 Scene 
LC82200682015161LGN00 and obtained drastically different outputs compared to 
the CFMask output obtained through USGS EarthExplorer's Surface Reflectance 
service and from the QA band itself. The CFMask and QA band show relatively 
similar cloud profiles however the Windows-based FMask product shows a 
completely cloud covered scene. 
Could you please look into this?
