TīmeklisUp and downsampling. Resampling refers to changing the cell values due to changes in the raster cell grid. This can occur during reprojection. Even if the projection is not changing, we may want to change the effective cell size of an existing dataset. Upsampling refers to cases where we are converting to higher resolution/smaller cells.
