Hi,
I've been using the new GeoPackage raster support in 2.0.1, and have
noticed some strange output from gdaladdo on certain datasets.
When producing an overview tile which is on the edge of the dataset, so
that it is not entirely covered by its child tiles, I get random data in
the parts of
Ok, I've opened a ticket for it here:

Hi,
I am having a bit of trouble with warping a dataset (an ECW file) with
multiple overviews. The base file is huge, so I am selecting the overview
that matches closest to my output resolution and makes an in-memory VRT of
this, consisting of the overview bands of the original image.
This seems
2.0 there will be a new class for handling this, the
GDALOverviewDaset. It's a bit early for me to move to 2.0 yet, but maybe I
should just make a similar dataset type in my own project. Would that be
more efficient than going via a VRT?

When using the same image in GeoTIFF with overviews, it works correctly,
which may indicate something with the ECW drivers. I suppose it must be
something triggered by something weird I'm doing though, or else I would
think that other people would have the same problem.
The weird thing is that if

Is this the best way to do it btw, or is it a better way to make use of
overviews when cutting out and reprojecting parts of a big image?
Thanks again for all your help :-)

Great, thanks!
I tried this, but got only a red image as result, so I guess only the first
channel was used.
This is the relevant code, where _ds is the input paletted data set
vrtDS = vrtDriver-Create(, origW, origH, 3, GDT_Byte, NULL);
double geoTransform[6];
Hi,
I'm using the GDALWarp api from C++ to reproject and cut various input
images. In general this works very well for my purposes, except that for
paletted images I have to use NearestNeighbour resampling,
I would like to use Bilinear or higher order resampling, and wonder if
there is any way

Hi, I'm having a strange problem that appears to be related to the GeoJSON
driver in GDAL 1.11.0
When reading a polygon geometry in geographical lat/lon coordinates, all my
coordinate values are returned in integer degrees.
after reading all fetures
setlocale(LC_NUMERIC, old_locale);
This is not the solution (I fixed it here
http://trac.osgeo.org/gdal/ticket/5461) but some kind of workaround.
Best regards,
Dmitry

Hi,
I am having a very strange issue when trying to use a custom error handler
in GDAL on windows.
The following simple example illustrates it:
#include cpl_error.h
#include iostream
using namespace std;
static void logGDALError(CPLErr eErrClass, int err_no, const char *msg)
{
cerr
Ah, genious! It worked perfectly :-)
Thanks a lot!

Hi Dmitry, and thanks for your answer!
I was actually looking at this patch earlier today, but I also wanted to
see if I could solve it without patching.
Will this patch be included in the official source?
Is it possible to do it the way I described in the previous mail?
Cheers,
Thomas
