  • maximum distance -1. What is that doing? Mar 1, 2019 at 21:51
  • Just checking you have built statistics on the output or ran info to check that is all the values in the raster Mar 1, 2019 at 21:52
  • -1 is default value. i tried 10 and 100 as well.

  • Min and Max in 'quality measure' and 'prediction' layer are same.
