Just as an interesting side-note: I tried to do a CreateCopy on one of these
files that was 7GB. Using CreateCopy() it took almost 2 hours. When I simply
copied to file contents using a cp command (this is CentOS), the copy takes
about a minute. I am not sure why that is so terribly slow in GDAL
Rodolfo,
I don't remember how to choose the matrix to be inverted here. However you
can read about GDAL's affine transformation coefficients in the
documentation for GDALDataset::GetGeoTransform() [1]. You can also find
relevant info at the GDAL Data Model page [2].

Hello All,
I'm working on a new PRISM driver, and it can now read the rasterbands from
all products. Now I'm working on reading the georeferencing data, and trying
to set the affine matrix coefficients. The format specification* says in
page 53 for one of the map projection fields:
Field No 58

Right, I can do this for my already opened and read-from data set. However, I
want to have a separate file. This means I have to copy that original data set,
right? I can't seem to figure out how to copy a data set without actually
copying the raster data (which is huge in comparison to the meta
Derek,
Writing into a raster band is a lot like reading into it. Use the function
you use to read the pixels to write the pixels back.
Don't forget to close the dataset at the end using GDALClose() [1]. Also,
check out the GDALFlushCache() and similar functions in [2].

Hello,
I think I started to ask about this before on this forum, but I have since used
GDAL a bit more and might be better to generate a new thread.
I have been using GDAL to read in NITF files, getting the RasterBand data, and
manipulating it, and displaying the results in my viewer.
Now, I w
Ivan,
Your suggestion represents a lot of work, but it's interesting.
I think, I'll use the existing code unless I feel blocked with it.
Regards
Nicolas
