Thank you for testing and finding the issue. Both commands work well
without infinity in Windows.
Big help for continuing to use GRASS GIS in Windows for the course.

Dear Shivam rai
There is no module called "d.tile", So it won't work.
What did you try with d.what.rast? Please post the command you tried !!

Hi all
The r.tile module don't have overwrite flag, so if we re run the module
with different parameters but with same output prefix name, then it will
rewrite output with out warning.
Is this intentional?
Another point is, if I use overlap option it adds double the overlap cells

Hi Anna
I am not sure if it is related, but I had similar issues with Sentinel JP2
files.
The solution was to use the ECW library to read the JP2 files instead of
JP2OpenJPEG/JPEG-2000 driver with OpenJPEG library.
I had to recompile gdal to add the ECW support.

Dear Nikos

solution i could find is the 'greenbrown' package in R. Atleast we could
make use of the GRASS-R interface to implement the work flow.

Hi Uttam
If I understand you correctly you want to reproject a landsat image from
sinusoidal to laea projection!!
You dont have to manually set the bounding box while reprojecting a raster,
as GRASS will take care of it.
First you create a new location and mapset with desired output projection ,
