Hi all,
I hacked the SetBand() method so as to report the new medata in
DERIVED_SUBDATASETS mdd. Now if I gdal info a S1 dataset I get :
$ gdalinfo -nogcp -mdd DERIVED_SUBDATASETS
s1a-s6-slc-vv-20150619t195043-20150619t195101-006447-00887d-001.tiff
Driver: GTiff/GeoTIFF
Files: s1a-s6-slc-vv-

Dear Even,
I'm not referring to a specific interpolation method. However, for
checking GDAL's behaviour, nearest-neighbor interpolation is surely the
easiest way. And yes, it may seem arbitrary whether to select only even
rows/columns or only odd rows/columns of the base image when
downsampling by

I guess the effect is the most distracting with nearest neigh

Hi,
The explicit feedback has been modest, but positive so far, so :
Motion 1: GDAL/OGR 1.11.5 RC1 is promoted to be the official 1.11.5 final
release.
Motion 2: GDAL/OGR 2.0.3 RC2 is promoted to be the official 2.0.3 final release.
Motion 3: GDAL/OGR 2.1.1 RC1 is promoted to be the official 2
You were right (what a surprise !). I pushed the new
GetMetadataDomainList() / GetMetadata() methods to gdaldataset, as well
as the fix for geotiff (and some other fixes).
Now works like a charm even with subdatasets.
Regards,
Julien

Hi Even,
has this improvement also being backported on previous versions (as an
instance 2.1.x, 2.0.x)?
Cheers,

Thank you, Jürgen! This is exactly what I was looking for.
Thank you,

No, trunk only.
You could as well use the SPARSE_OK=TRUE creation option to avoid writting
blocks at all. Provided that your reader knows how to deal with tile/strips
with a 0 byte count
Hi Even,
thanks I'm already using the SPARSE_OK=TRUE to create an empty tiff
and afterwards warp input files on that with SKIP_NOSOURCE=YES.
I have already updated the ImageIO-EXT's TIFFImageReader to deal with
tile/strip with zero byte count.
Final question:
Starting from which GDAL version, SPAR

Hi, Jürgen. Do you happen to know of similar tests for the output
executables and libraries?
Thank you,
Chris

Dear developers, I thought people on this list might find my latest little
tool entertaining and/or useful:
https://github.com/daleroberts/tv
... and thank you for the great subsampling feature in GDAL 2. I've used it
on a couple of different projects and it's fantastic.
_
I'm in need of "max" resampling in gdaladdo, to preserve the highest points
in elevation raster overviews. I've found that gdalwarp supports "-r max",
but gdaladdo doesn't.
Can I achieve what I need (with prebuilt GDAL binaries)? (How?)
Will future versions of gdaladdo support "-r max"? (When?)
