Hi
Julius.
If
I understand you correctly, this is a Arc question.
IFF
the values exist in your output file. You can test by
loading your results file in a new process and
rasterio.plot.show().
Arc
tries to display a byte file for values between 0-255, hence
no contrast between 0 and 1. In Arc, open the layer
properties of your new GTiff and adjust the display values
under the symbology tab.
If
not and the results file is all zeros then it is probably
and error in your code. I had a similar issue where I
incorrectly set the value NBITS =1 when calling
rasterio.open() and on linux systems my output was empty.
Good
luck.

Hello everybody,
I´m quite new to rasterio and Python, but my task is, to
produce binary raster files based on the information of
sentinel2 satellite images (GTiff). Therefore I use Spyder IDE
and the numpy.where() method to calculate new arrays and save
them as GTiffs.
Although the output arrays contain 0 and 1 values, the output
tif only shows black (in the shape of the original gtiff), if
opened with standard image viewer or ArcGIS Desktop. Only if
opened via Python script in Spyder, I am able to display the
output tifs as expected (using rasterio.plot.show() method).
If anybody has an idea, what the problem might be, I would
appreciate any help.
Thanks!
