你必须做更多的工作
dir.create("test")
setwd("test")
f <- paste0("test", 1:nlyr(s), ".tif")
r <- writeRaster(s, f, overwrite=TRUE)
list.files()
# [1] "test1.tif" "test2.tif" "test3.tif"
r
#class : SpatRaster
#dimensions : 10, 10, 3 (nrow, ncol, nlyr)
#resolution : 36, 18 (x, y)
#extent : -180, 180, -90, 90 (xmin, xmax, ymin, ymax)
#coord. ref. : +proj=longlat +datum=WGS84 +no_defs
#sources : test1.tif
# test2.tif
# test3.tif
#names : lyr.1, lyr.1, lyr.1
#min values : 0.02075680, 0.01058152, 0.02179740
#max values : 0.9874134, 0.9990475, 0.9883418
这也有效:
names(s) <- c("a", "b", "c")
x <- writeRaster(s, names(s), overwrite=TRUE, filetype="GTiff")
但请注意,文件名没有 tif 扩展名
sources(x)
# source nlyr
#1 ./test/a 1
#2 ./test/b 1
#3 ./test/c 1
所以我会做
z <- writeRaster(s, paste0(names(s), ".tif"), overwrite=TRUE)
#class : SpatRaster
#dimensions : 10, 10, 3 (nrow, ncol, nlyr)
#resolution : 36, 18 (x, y)
#extent : -180, 180, -90, 90 (xmin, xmax, ymin, ymax)
#coord. ref. : +proj=longlat +datum=WGS84 +no_defs
#sources : a.tif
# b.tif
# c.tif
#names : a, b, c
#min values : 0.02075680, 0.01058152, 0.02179740
#max values : 0.9874134, 0.9990475, 0.9883418
