I have ~1000 1GB images that I want to make into a COG w/ JPEG compression. Any time I try to use gdalbuildvrt to create a vrt of my entire directory of images then I get big quality loss.
Can someone show me what I'm doing wrong?
Left image is a sample of how I'd like to make my entire directory of images into a single COG. This VRT has only 2 images, N00-E000_ur and N00-E000_ul.
gdalbuildvrt test.vrt *.tif
gdal_translate test.vrt testjpg90vrt.tif -of COG -co COMPRESS=JPEG -co QUALITY=90
Right image is just a comparison of making a COG from just 1 of the images:
gdal_translate N00-E000_ur.tif N00-E000_ur_cog_jpeg.tif -of COG -co COMPRESS=JPEG -co QUALITY=90
