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.

 

Ale
