Dear All,

I want to subset a large spatial grid (2000*2000) into many smaller
grids for further processing in my simulation models. Could anyone do it
before and any tips will be highly appreciated?

Map <- readGDAL("yong.img")  # one image from erdras imagine
Map$va <- Map$band1
Map$band1 <- NULL
Map1 <- a subset of Map$va based on selected cols and rows.
