WebSep 26, 2024 · The resampling method defined by the -r argument is also important. Using -r near uses nearest neighbour, which just picks whatever pixel in the original data that happens to be closest to the center of the pixel in our warped profile. This is not always representative for the rest of the contributing pixels. ... GDAL uses sensible defaults ... WebDetails. This is an R wrapper for the 'gdalwarp' function that is part of the Geospatial Data Abstraction Library (GDAL). It follows the parameter naming conventions of the original function, with some modifications to allow for more R-like parameters.
