将多层 RasterBrick 保存到硬盘 [英] Save multi layer RasterBrick to harddisk

问题描述

我有一个表示地形图的多层 RasterBrick，我想将其以 grd 或 tif 格式保存到硬盘，以便其他人以后可以使用.

I have a multilayer RasterBrick representing a topographic map that I want to save to the harddisk as grd or tif format, so that others can work with later.

这是 RasterBrick:

This is the RasterBrick:

class       : RasterBrick 
dimensions  : 2400, 4200, 10080000, 3  (nrow, ncol, ncell, nlayers)
resolution  : 100, 100  (x, y)
extent      : 480000, 9e+05, 62000, 302000  (xmin, xmax, ymin, ymax)
coord. ref. : NA 
data source : in memory
names       :  layer.1,  layer.2,  layer.3 
min values  :   2.8725,   2.8725,   2.8725 
max values  : 254.5175, 254.5175, 254.5175 

我试图用这个命令保存它:

I tried to save it with this command:

outfile <- writeRaster(brick, filename='grid.tif', format="GTiff", overwrite=TRUE)  

还有这个:

outfile <- writeRaster(m, filename='grid.grd', format="raster", overwrite=TRUE)  

但是 tif 文件已损坏，并且 grd 对象仅包含一层，并且当我使用 raster() 读回它时未被识别为多层 RasterBrick.

But the tif file is corrupt and the grd object only contains one layer and is not recognized as multi layer RasterBrick when I read it back in using raster().

目的是将地形图用作专题图的背景.

The aim is to use the topographic map as background for thematic maps.

推荐答案

试试这个:

outfile <- writeRaster(brick, filename='grid.tif', format="GTiff", overwrite=TRUE,options=c("INTERLEAVE=BAND","COMPRESS=LZW"))
