Hi,
I repeated the steps which are described in this question
https://gis.stackexchange.com/questions/317916/gdalbuiltvrt-output-is-different-than-the-source-images-when-using-dstalpha

original images is lost if I read

understand.

On page https://www.gdal.org/ogr2ogr.html I can read from the Performance

In the documentation of GDAL config options I noticed this:

Hi,
I try to run validate_gpkg.py that I downloaded today from GitHub. I run it
under OSGeo4W installation on Windows, GDAL version GDAL 2.3.2, released
2018/09/21, and Python version Python 2.7.14.
Validation stops at this error message:

Hi,
The names of the raster bands seem to be stored into GeoTIFF with GDAL tag 42112
Tag 42112:
SomeBandName 001
SomeBandName 002
The description can be set with Python by doing something like
RasterBand.SetDescription(BandName)
I guess that those metadata items can be added also with

Hi,
I wonder if there is some issue in gdalwarp and how it is using the GPKG raster
driver with a predefined tiling scheme. Feels like gdalwarp does not use any
ZOOM_LEVEL_STRATEGY, if not one called "strict".

Hi,
What does GDAL do when it reads the whole GeoJSON file as "GeoJSON: First
pass"? Could it make the total process faster if user could give the same
information that is gathered with the First pass somehow directly, or is that
step needed in any case?
Microsoft has an excellent GeoJSON
Hi,
I was doing some tests with GeoPackage rasters and found that if I define
-a_srs then also -co RASTER_TABLE is required which feels unnecessary.
Steps to reproduce:
Create initial gpkg
gdal_translate -of GPKG global_mosaic_0.png raster.gpkg -a_srs epsg:4326
Try to add a subdataset and

I wonder what would it need to store vector tiles into GeoPackage instead of

Hi,
Are there any examples available about how to convert some DEM data into
GeoPackage according to the Tiled Gridded Coverage Data extension that GDAL 2.3
supports?
