运行堆叠栅格列表时如何解决错误问题？

问题描述

在运行堆叠栅格列表时如何解决此问题？这是我运行的程序，

library(raster)
setwd("E:\\Gis-shp\\Chaurjahari\\LC08_L1TP_143040_20191016_20191029_01_T1.tar")
raslist <- paste0('E:\\Gis-shp\\Chaurjahari\\LC08_L1TP_143040_20191016_20191029_01_T1_B',1:11,".tif")
raslist
landsat8 <- stack(raslist)

返回

library(raster)
setwd("E:\\Gis-shp\\Chaurjahari\\LC08_L1TP_143040_20191016_20191029_01_T1.tar") raslist <- paste0('E:\\Gis-shp\\Chaurjahari\\LC08_L1TP_143040_20191016_20191029_01_T1_B',".tif") 
 raslist [1] "E:\\Gis-shp\\Chaurjahari\\LC08_L1TP_143040_20191016_20191029_01_T1_B1.tif"
[2] "E:\\Gis-shp\\Chaurjahari\\LC08_L1TP_143040_20191016_20191029_01_T1_B2.tif"

landsat
8 <- stack(raslist)
Error in .local(.Object,...) :  Error in .rasterObjectFromFile(x,band = band,objecttype = "RasterLayer",:    
    Cannot create a RasterLayer object from this file. (file does not exist)

解决方法

您可以看到哪个文件不存在

file.exists(raslist)

您也可以尝试类似的操作

library(raster)
setwd("E:\\Gis-shp\\Chaurjahari\\LC08_L1TP_143040_20191016_20191029_01_T1.tar")
raslist <- list.files(pattern="LC08_L1TP_143040_20191016_20191029_01_T1_B.*tif$")
landsat8 <- stack(raslist)
