I am calculating a moving average for 601 rasters (720, 1440)and it is taking
a day to finish. I wonder if this is normal or something is wrong
I am using Linux .
code:
dir1 <- list.files("/home/spa4-358-4-365", "*.img", full.names =
TRUE)
saf=stack(dir1)
meansmosas <- overlay(saf,fun=function(x) movingFun(x,
fun=mean,n=35, na.rm=TRUE))
info:
saf
class : RasterStack
dimensions : 720, 1440, 1036800, 601 (nrow, ncol, ncell, nlayers)
resolution : 0.25, 0.25 (x, y)
extent : -180, 180, -90, 90 (xmin, xmax, ymin, ymax)
coord. ref. : +proj=longlat +datum=WGS84 +no_defs +ellps=WGS84
+towgs84=0,0,0
