I am deploying QGIS 3.6 on Windows 10.
Raster > Projections > Warp (Reproject) tool, I need to reproject a single-band,
float32, GeoTIFF DEM from EPSG:3413 to EPSG:3857.
The output raster must snap to a pre-existing GeoTIFF, also in EPSG:3857.
PROBLEM: The tool does not include a snapping option. The tool's help page is silent on snapping, as is a Google search.
There is a curious input section entitled
"Additional Command Line Parameters". But again, no guidance.
How to include snapping when reprojecting?
