So I have done some RGB-channel extraction from a .tif file, meaning I took UAV_image.tif and I have extracted R,G,B channels on three different .tif files. Next, I did some calculations such as result = ((red^2)+(blue^2))/(blue). For all the previous operations I used mainly cv2.imwrite and tiff.imread commands. The problem is that the resulted .tif does not contains coordinates.. How can I copy the coordinates from the initial UAV_image.tif to result.tif? I tried to followed this tutorial:
Use gdalsrsinfo to get the srs of the tiff that still has the projection:
gdalsrsinfo -o wkt tiffwithsrs.tiff Then copy the output and use gdal_translate to apply it to a new tiff:
gdal_translate -a_srs '...' tiffwithoutsrs.tif newfixedtif.tif just paste your projection after the -a_srs option
But the result was to copy both coordinates and colors...!!! Did I do something wrong?
Also, this guy here: "Copy" Image coordinates to another image that is nd.array has a an approach that does not fit my problem, because I do not do any kind of Machine Learning training (as I see to his example - correct me If I am wrong) and I do not use nd.array.
So, the question is how do I copy coordinates from a .tif image that has coordinates to a .tif image that does not have coordinates?
