Hi Frank, et al,
I'm working with GDAL 1.5.3, released 2008/09/09 built with libjasper
so I can process some DOQQ composites and chop them into smaller tiles.
Below is a typical image but I get a bunch of errors in gdalinfo. The
system has like 6 GB of memory and only about 1.5GB of swap. The
compressed image is huge at 538MB. I tried 3-4 images in the directory
and got the same report on all of them.
Any thoughts on this?
Is this a real problem, ie. I will not be able to access these images.
Other options solutions?
Steve,
I'm not familiar with the "cannot get box" error you are seeing, but
generally speaking the JasPer based JPEG2000 driver is not suitable for
use on large images due to it's decode-the-whole-image-in-memory model
of imagery access.
Best regards,
Band 1 Block=256x256 Type=Byte, ColorInterp=Undefined
error: expecting signature box
Metadata:
LAYER_TYPE=athematic
error: cannot get box
<GDALRasterAttributeTable/>
error: cannot get box
I must be a Zen thing that I always find answers after a give up looking
and post to the list. So, to reply to myself, I was about to use the
JP2MrSID driver like the following and without any error. So, I'll try
to move forward using this more of access. I'm still interested in any
other thoughts you have on the above issues.
