potentially more subelements that can go in this top level section but I
was not sure if they would work across all types of pixel functions.
P.S: Is there a reason why SkipNonContributingSources is False by default?
Wouldn't it

Dear GDAL Community,
I am encountering a performance issue when using a VRT consisting of a
large number of source rasters and built-in C++ pixel function ("max"). I
would appreciate any guidance on whether some GDAL config option can
improve this, or I am doing something wrong, or this is a poten

Hello,
I am looking for functionality to create a VRT of multiple rasters where
the VRT pixel value is the maximum of underlying rasters pixel values.
I found out that we have pixel functions

we can add to VRTs to get this

I am developing a compiled program in Golang that calls GDAL through
subprocess calls. In one of the program's features that I am developing, I
want to call *gdal_ls*. However, I see that gdal_ls is not available in
PATH by default and hence can't be called directly in a terminal without
