I have a single band GeoTIFF image which displays correctly in QGIS. However I tried viewing the same file using matplotlib and rasterio but I get a different output. Is there something that I am doing incorrectly? How do I display it like it is in QGIS? I would also like to use a colour map for representing the different values of the single band with a color. The EPSG of the GeoTIFF is 4326.

Here's my code:

import os
import rasterio
from rasterio.plot import show
from mpl_toolkits.basemap import Basemap
from matplotlib import pyplot as plt
from osgeo import gdal

if __name__ == "__main__":

    input_Dir = 'generated_46.tif'

    tiff_file = input_Dir
    raster = rasterio.open(tiff_file)

    bbox = raster.bounds


Here's how it appears in qgis:

And this is my python output: enter image description here

Here is the GeoTIFF description: enter image description here enter image description here

  • Check you min and max values! You should outspread them to 0-255 integer range. It is done by QGIS automatic.

  • raster = raster / (max(raster) - min(raster)) * 256

This did it

raster = rasterio.open(tiff_file)

instead of this:
