Hello, I needed a way to create virtual datasets in a way similar to what gdal_translate is doing. I noticed that gdal_translate is basically a tool to construct a VRTDataset, so I proceeded by transforming gdal_translate.cc into a VRTDataset builder class.
The result is gdaltranslate.{h,cpp} in
http://meteosatlib.svn.sourceforge.net/viewvc/meteosatlib/gdal/trunk/utils/
(I did not deal with subdatasets because it is a part of GDAL I have not
explored yet).
I reckon such a VRTDataset generator could be useful to many, and since
its interface (necessarily) closely matches the way gdal_translate
works, it is also quite easy to learn.
Could it make sense to package GDALTranslate as part of GDAL, and just
rebase gdal_translate off it?
From chats on IRC I get the feeling that it is quite customary to take
"inspiration" from gdal_translate.cpp when creating virtual datasets.
I would love if that happened, because that will guarantee that
updates/fixes to gdal_translate are readily available also to the other
code based on GDALTranslate.
Ciao,
Enrico
