I'm working with some TIFF images, and I want to add another band to an existing image.

Here's the code that I use to read the image:

# Read the image
image = rasterio.open('input.tiff')

with rasterio.open("input.tiff", 'r+') as src:
   crs = rasterio.crs.CRS({"init": "epsg:4326"})
   src.crs = crs

With this code, I'm able to change the CRS: here's the meta of image:

{'driver': 'GTiff',
 'dtype': 'uint8',
 'nodata': None,
 'width': 524,
 'height': 499,
 'count': 3,
 'crs': CRS.from_epsg(4326),
 'transform': Affine(1.0, 0.0, 0.0,
        0.0, 1.0, 0.0)}

I want to change the count value from 3 to 4.

I'm using rasterio.

Thanks in advance.

You can read the metadata using .profile and then update it.

with rasterio.open('input.tiff') as r:
      profile = r.profile

profile.update(count = 4)
profile.update(crs = 'EPSG:32643')
