Regarding your immediate issue, the workaround I see would be that you
use PROJ to create a regular grid that contains the vertical
correction, use gdalwa
r extending the scope of gdalwarp to the
3D-space.

Regarding your immediate issue, the workaround I see would be that you
use PROJ to create a regular grid that contains the vertical
correction, use gdalwarp to transform it to the exact extent and
resolution of the result of your 2D-only gdalwarp, and finally use
gdal_calc to sum the two.
Kristian,
your question kind of intersects

Two part answer:
A) I guess that there's an issue with axis order and units in your
pipeline. In particular if your DHYMSEA_1km_6150_542.tif has a EPSG
geographic CRS set, then the
Hi list,
I am trying to apply a custom vertical transformation to a grid using gdalwarp
and am struggling a bit to get the results I want. It's entirely possible I am
trying something not within the capabilities of gdalwarp but I am sure someone
here can help me figure that out.
I am devising
