Preface: I am fairly new to GIS, and as such - I haven't wrapped my head around the terms. I'm trying to vertically concatenate several tall JPEG-in-TIFF files into a single file. I've attempted using a combination of gdal_create followed by gdalwarp, but this results in the TIFF files being layered over each other at the start of the final image, rather than being appended end-to-end as intended. My goal is to achieve this concatenation using command line tools, without compromising the original images' quality or metadata.
Here's an example of the gdalinfo output of 1 of the files:
gdalinfo 1.tiff
Driver: GTiff/GeoTIFF
Files: 1.tiff
Size is 523, 771030
Metadata:
TIFFTAG_RESOLUTIONUNIT=2 (pixels/inch)
TIFFTAG_XRESOLUTION=25.4
TIFFTAG_YRESOLUTION=25.4
Image Structure Metadata:
COMPRESSION=JPEG
INTERLEAVE=PIXEL
JPEGTABLESMODE=1
JPEG_QUALITY=100
Corner Coordinates:
Upper Left ( 0.0, 0.0)
Lower Left ( 0.0,771030.0)
Upper Right ( 523.0, 0.0)
Lower Right ( 523.0,771030.0)
Center ( 261.5,385515.0)
Band 1 Block=128x128 Type=Byte, ColorInterp=Red
Band 2 Block=128x128 Type=Byte, ColorInterp=Green
Band 3 Block=128x128 Type=Byte, ColorInterp=Blue
I am starting with this:
gdal_create -of gtiff -outsize 523 12646632 -bands 3 -co BIGTIFF=YES -co TILED=YES -co JPEG_QUALITY=100 -co COMPRESS=JPEG -co INTERLEAVE=PIXEL -co JPEGTABLESMODE=1 -mo TIFFTAG_RESOLUTIONUNIT=2 -mo TIFFTAG_XRESOLUTION=25.4 -mo TIFFTAG_YRESOLUTION=25.4 concat_combined.tiff
and then attempting to concatenate existing TIFFs like this:
gdalwarp -to SRC_METHOD=NO_GEOTRANSFORM -to DST_METHOD=NO_GEOTRANSFORM ./1.tiff ./2.tiff ./3.tiff concat_combined.tiff
