[gdal-dev] VRT with attribute filter?

2012-05-17 Thread Tyler Mitchell
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

[gdal-dev] Re: Effeciency of "ReadRaster" in different storage format of mulit-band image

2012-05-17 Thread hitweiran
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. On Thu, May 17, 2012 at 2:09 PM, Even Rouault wrote: > Le jeudi 17 mai 2012 20:04:30, Jayesh Chaudhary a écrit : > > Folk

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
