I combined (Merge) 130 DEM maps via QGIS, taking up 3 GB in total. However, the total size of the combined file was 7.4 GB. I'm new to QGIS. It's only been a few weeks. I don't understand why the file size increased so much. Is it possible to set the total size to 3 GB? Both original files and output files are TIFF.
The path I follow is this: ''Raster'' - ''Miscellaneous'' - ''Merge''.
I used ''Float32''. No profile or other option selected.
Input files are 96 DPI, 16 bit, 3601x3601. There is nothing in the properties section of Output File. Output file cannot be read with any program other than QGIS. It appears as a corrupt file.
