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
https://lists.osgeo.org/pipermail/gdal-dev/2016-September/045134.html that
we can add to VRTs to get this
Owen,
Please create a ticket about that.

Hey all,
I work with Kurt Schwehr, and we've been debugging failures where an

Tim,
Reviewing the warping logic, I see we have support for a *input* mask,
but not creating/updating an *output* mask. AFAICS, there isn't any
particular strong reason not to have support for that. Likely just a few
hours of coding away. Your best workaround is to generate an output with

WOW! Game changer.
Any preliminary documentation on this?

Hi Abdul,
For the specific case of multiple rasters that share the same extent, the
next release of GDAL should have a replacement "gdal_calc" that would take
multiple inputs and write a VRT that applies an expression to those inputs
("max", in your case). In the meantime, I think your best option
Thanks for your reply, my rasters are not sharing extent but some do
overlap.
How about GTI, Does that provide this functionality? Do you know.
