: [gdal-dev] help resampling raster to coarser scale Hi Etienne! What if you first process the original fine resolution image with a filter (low-pass, median, or manually created pixel function). Then the result, which is a fine resolution image but smoothed, could be resampled with the nearest

Hi Etienne! What if you first process the original fine resolution image with a filter (low-pass, median, or manually created pixel function). Then the result, which is a fine resolution image but smoothed, could be resampled with the nearest neighbor. Anton On 08/05/2011 03:57 AM, Etienne

Hi all, I am trying to resample a raster with categorical data (land surface vegetation/cover) from a high resolution (500m) to a coarser resolution.    I would like to do something similar to what the GRASS operator r.resamp.stats does, using the modal category present in the higher resolutio
