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
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
Tams:
I extract the first band of that multiband image and save it as another
img file, then the read to that single band is successful ! So maybe the
mistake is due to the code get first band?

I am sure the original data is available, because I see the imges in ENVI and
have loaded it to MATLAB, so how can I inspect the values by
gdallocationinfo??Thanks !

Thank for both of you, I will try according to your suggestion.

I want to read a multiband image(in format of .img) by using method
ReadRaster, however, I encount some problems. I just can't understand why
the data loaded to memory is wrong?
the code is like this
OSGeo.GDAL.Dataset dataSet =
OSGeo.GDAL.Gdal.Open(@"G:\building.img",OSGeo.GDAL.Access.GA_ReadOnly
