I am using gdal_translate and a .vrt to take 115 .jp2 files from the USGS, pull them together and then export a lower resolution .jp2.
This is with GDAL 1.10 on OSX. gdalinfo --version GDAL 1.10.1, released 2013/08/26 When I run gdal_translate, it gets about 30% of the way through the process and errors out saying that it can't open one of the .j2w files. When I run gdalinfo on the file, I can open it, and if I run gdal_translate on just that file, I can successfully export a reduced resolution copy. The output of gdalinfo is here: https://gist.github.com/fawcett/beead31741e24394b38e I can also load the .vrt image into QGIS 2.2 and it loads (slowly of course). gdal_translate img_index.vrt mpls34.jp2 -outsize 10% 10% -of JP2OpenJPEG -co QUALITY=25 -epo Input file size is 45000, 65000 0...10...20.ERROR 4: CSLLoad2("/Users/david/projects/mpls_watersheds/data/15TVK830815_201203_0x3000m_CL_1/15TVK830815_201203_0x3000m_CL_1.j2w") failed: unable to open file.
