Hello, I am trying to reproject a raster image from sinusoidal projection using “projectRaster”. The size of the image is not very big (922 KB), but when applying the reprojection I get this error message: “Error: cannot allocate vector of size 7.1 Gb”. Please see the code below:
HDFpath <- "C:/images/" # dir with images setwd(HDFpath) # set working directory library(raster) library(rgdal) geocrs <- "+proj=longlat +ellps=WGS84 +datum=WGS84" tile <- brick(“image.tif”) tile_reproj <- projectRaster(tile, crs=geocrs) Error: cannot allocate vector of size 7.1 Gb > tile class : RasterStack dimensions : 2400, 2400, 5760000, 1 (nrow, ncol, ncell, nlayers) resolution : 463.3127, 463.3127 (x, y) extent : -11119505, -10007555, 5559753, 6671703 (xmin, xmax, ymin, ymax) coord. ref. : +proj=sinu +lon_0=0 +x_0=0 +y_0=0 +a=6371007.181 +b=6371007.181 +units=m +no_defs names : INCA.h08v03.Dormancy_median min values : 19 max values : 540 _______________________________________________ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
