problem with feeding input files into gdal_merge.py

Question

While merging the files using gdal_merge.py the following code works:

subprocess.call([sys.executable,gmerge,'-o','C:\\r.tif','-of','GTiff','D:\\a.tif','D:\\b.tif'],shell=True)

However, when the input files are numerous, each file can not be inserted separately. In this case, the following code does not work:

subprocess.call([sys.executable,gmerge,'-o','C:\\r.tif','-of','GTiff','D:\\*.tif'],shell=True)

I did not know how to input the input files. Any idea is welcomed.

Answer 1

you can loop on your files and append them to your list

command = [sys.executable,gmerge,'-o','C:\\r.tif','-of','GTiff']

images = glob.glob("D:\\*.tif")
for image in images:
    command.append(image)

subprocess.call(command)
