i.landsat8.swlst's Issues

MTL issue

Hello Nicos,

Im trying to run your grass add-on and I get an error dealing with MTL file informations. I get a message:
AttributeError: 'metadata' object has no attribute
'LANDSAT_SCENE_ID
And when I look at MTL file it doesnt contains any LANDSAT_SCENE_ID item.
Landsat product i'm working on is https://doi.org/10.5066/P975CC9B
It seems id looks like LANDSAT_PRODUCT_ID in this product...
Is there any way to make your add-on working with this product?

Thanks

Check _derive_adjacent_pixels function

Your function

def _derive_adjacent_pixels(self):
        """
        Derive a window/grid of "adjacent" pixels:
        [-1, -1] [-1, 0] [-1, 1]
        [ 0, -1] [ 0, 0] [ 0, 1]
        [ 1, -1] [ 1, 0] [ 1, 1]
        """
        return [[col-1, row-1] for col in xrange(self.window_width)
                for row in xrange(self.window_height)]

returns only all adjacent pixels for a 3 pixels neighborhood. In a 7 pixels neighborhood the window goes still only one pixel up and to the left. Is that on purpose?

I can make create a pull request if you want a full window for all neighborhood sizes...

No raster created

Hello, like the title says, I got no raster output unfortunately. Only some files in cell_misc/lst/. Do I miss a step? Thanks for your help!
Kind regards, Sebastian

Application on Space-Time-Raster

Firstly, thanks a millions for this nice algorithm. Further, I wanted to ask, if it is possible to apply the algorithm to a space-time landsat raster.
Kind regards.

Duplicate Variables in MTL

Using the L1C2 (collection 2) Landsat 8, the MTL files now contain some variables twice. When the addon parses this MTL, it fails with "Duplicate Variable ORIGIN" etc. for each such variable

Here's a list of the duplicates that I found:

diff LC08_L1TP_174039_20220118_20220123_02_T1_MTL.txt LC08_L1TP_174039_20220118_20220123_02_T1_MTL.txt.bak

After removing these duplicates from the MTL, I was able to successfully run the addon.

Metadata-Structure .xml

Apparently, with Landsat8-Data a new metadata file structure emerged. Data is provided with an xml file (xml is not supported with github, so i zipped it).

LC08_L1TP_094073_20160219_20170329_01_T1.zip

Is there a way to make the addon work with the new metadata-structure? I found no possibility to back-convert the xml-file.
Thank you!
