Is there a way I can sample random raster pixels from a satellite image with QGIS or QGIS plugin? I also need each randomly-chosen pixel to have a pre-defined minimum distance from the other raster pixels. I need this pre-defined minimum distance in order to minimize spatial autocorrelation.

  • What is your desired output? A table with the values? A new raster wherein the randomly selected pixels are the only non-NA values? – Jackson Jan 28 at 2:36
  • I want to sample random raster pixels with minimum distance and output as a tiff file. – J. P. Jan 28 at 17:06
