I apologise from the outset. I need a full run through of working gdalwarp to downsample a raster to match another i.e. How to resample GeoTIFF images to the same resolution?. Using QGIS 2.12.
Using '-tr switch' what command goes in next so I specify the resolution to switch too.
Or how do I find the resolution from each raster to ascertain the height and width values necessary?
