Dear FWtools list,
I am having problems getting a large merge fire-up using the gdal_merge command.
I have three IMG (HFA format) files in the same projection (lat/lon) each 22Gb, 20Gb and 6Gb that I am trying to merge into a single image.
I keep getting the following -
Q:\satimages>gdal_merge -o qldg.img -of HFA -v z54gclip.img z55gclip.img z56gclip.img
File Size: 48826x154049x3
Pixel Size: 0.000130 x -0.000130
Copy 0,0,48826,154049 to 0,0,48826,154049.
Traceback (most recent call last):
File "C:\PROGRA~1\FWTOOL~1.0B2\bin\gdal_merge.py", line 488, in ?
fi.copy_into( t_fh, band, band, nodata )

File "C:\PROGRA~1\FWTOOL~1.0B2\pymod\gdal.py", line 845, in ReadRaster
Any suggestions ?
