Dear All I trained a neural network for 200 data and I did prediction for a grid file (e.g. 1000000 points) such as below: snn<-predict(nn, newdata=data.frame(wetness=wetnessgrid$band1, ndvi=ndvigrid$band1)) the pixels of snn is same with wetnessgrid or ndvigrid I want to convert this file (snn) to a map that I can open it in GIS software. Thanks alot [[alternative HTML version deleted]]
