Thanks Even.
Whether this algorithm internally use Convex Hull or Concave Hull?
How to get Concave Hull-based union geometry using GDAL?
Are these functionalities (ogr.CreateGeometryFromWkt..) available with C#
bindings?

Rajesh

I think the official source for all platform is Conda - and that certainly
work and gets gdal 3.2.2 on ubuntu for me.
conda install -c conda-forge gdal
if you don't have conda - you can install miniconda from here

its doc. gdal_translate should be fine. But when res

But indeed, the possibility to use VRT does seem better since then it can be
done during tiling. This probably only saves space and not time, correct (due

Hello,
When compiling gdal-3.2.2 I get an error due to a missing SQLLite3 link
library.
Downloads from the SQLLite site do not appear to provide, or compile to, a
'sqlite3.lib' file at all.
Is there any way to disable the sqlite3 feature in the gdal build?
Alternately, where is the 'sqlite2.li
Hi,
First, be sure to "pip3 install -U pip" to get latest pip as got some
issues with wheels build because was using outdated pip.
In https://pypi.org/project/GDAL/, there is a mention that gdal python
bindings have dependencies e.g
* libgdal (3.2.2 or greater) and header files (gdal-devel)
* nu
For some time i have been trying to install the latest version of GDAL or
anything above 3.1.0 on my ubuntu 20.04 system, unfortunately the version
that keeps being installed is 3.0.4 which is outdated for the uses we need.
I have followed several online guides but keep hitting the same issue.

"gdal_translate -scale 0 1 0 factor in out" could also be used. As a
bonus point, this works with VRT as an output if you don't want to
materialize the intermediate file.

Rajesh,
Use geom_collection.UnionCascaded() where geom_collection is a
GeometryCollection / MultiPolygon of your many polygons. See
