Hi All,
I have 10 raster (DCM_1_power10.sgrd, DCM_1-power11.sgrd, etc etc) and 1 polygon shape-file (sierraplots.shp) with several plots (circular) with one field data [V]. I have the following question. I wish to sum the value of pixel inside the polygon with R+SAGA and correlate the plots value of [V] with the sum of value of pixels inside the plots with a correlation coefficient. This for every grid and to see the best r^2 and RMSE. Thank You for the help and all suggestion.
