Merge raster data with GDAL in Python

Code:

from osgeo import gdal
import glob
import subprocess

# list all files in directory that match pattern
print(demList)

# gdal_merge

# build virtual raster and convert to geotiff
vrt = None

Thanks for the short tutorial. Here is an alternative: gdal_merge.py -o large_output_raster.tif your/raster/folder/*.tif Make sure you have gdal installed and run it in terminal.

Fantastic, thank you so much. I have spent much longer than I should working out how to loop this through an entire directory of images, which will save so loads of time in future.

You must a good researcher in RS. Thanks for your help

Is there a way to add multiple geotiff files( like markers or houses) on an other geotiff file?

How did you merge python to QGIS to work instantly and show the result? Can you please let me know if there is a video for it. Thank you

Hiii, I'm using the virtual raster method but not all the tifs are being merged :( what should I do?

Can you make video on custom dataset of raster(geotiff image)dataset.

Hi, the output file size becomes too large after merging. Could you please explain how to fix this?

[rubencrespo]

I don't understand the subprocess.call function. I understand that you concatenate the cmd with the DMElist, but why is the split needed. Awesome tutorial, thanks!

Great video! I've merged a couple of datasets with no issue, but now I get this error:
ERROR 1: ZIPDecode:Decoding error at scanline 0
ERROR 1: TIFFReadEncodedTile() failed.
ERROR 1: \\Path to this file...\DTM_1km_6159_636.tif, band 1: IReadBlock failed at X offset 0, Y offset 0: TIFFReadEncodedTile() failed.
the data is from Denmark and I've got different offset values like x=6, 1 or 8 and y=5 or 6
I've been stuck on this problem for a while and tried all the solutions I've found on the internet, have you encountered this problem before?
