Computing footprint error

Hi Daniel,

I am running into the following error, which I am not able to fix (see error message further down)

Data overlap. Same projection, type, source, nodata, both are overlapping

• ref image doesn't have super great quality, this was more a technical test. Same error in other places

Data download

I tried to play around with no data (with, without, image size, etc.)

Platform:

• Windows 10
• Anaconda environment with python 3.7.X
• arosics (1.4.3) - same error with higher version

Input

REFERENCE = r'reference_image\reference.tif'
INFILE = r'input_images\target.tif'    
outfile = r'output_files\out.tif'  

# detect and correct global spatial shift 
CR = COREG(REFERENCE, INFILE,
           max_shift=200, path_out=outfile, 
           fmt_out='GTIFF',
           out_crea_options=['COMPRESS=DEFLATE'],
           r_b4match=1, 
           s_b4match=1)

Output

Calculating footprint polygon and actual data corner coordinates for reference image...
