I've done my best to comb through the code but can't see how to use an
attribute filter in a (OGR) VRT definition. Yet, I see an old ticket from Bart
that was asking for it and seemed to be implemented. Or am I reading too much
into this? Any one using it?
http://trac.osgeo.org/gdal/ticket/9
My question is when the format of data is BIL or BIP, the efficiency of
Band.ReadRaster is quite low. How should I optimize code?
I converted one mulit-band image into all the three formats and found that
BSQ can read image in the most efficient, the other two is inefficient. So I
don't know how c

Thanks Even.
I realised that I was using OpenJPEG driver (some old version) which does
not support overviews. I intend to use MrSID which worked as expected.
Thanks a lot.

Folks,
I have written a GDAl based reader and I am trying to read JPEG 2000
images. When I ran gdalinfo on one of the samples images from here:
http://www.openjpeg.org/index.php?menu=samples, it does not list subdataset
or overviews ( I was expecting overviews ).
I am wondering what I am missing.
Thanks a lot, Even. I will give it a try.

No, it will read it by small chunks. If no matching XML schema is availabl
You may want to post on the postgis-users list as I believe the
developers of the PostGIS Raster driver can be found there.

Hello, everyone.
There are two methods to extract data from a mulit-band remote sensing image
in GDAL.
1. Dataset.ReadRatser, that can read all data in mulit-band image.
2. Band.ReadRaster, that can read only one band of mulit-band image.
Actually, there are three formats used to storage mulit-band
