[R] Fwd: netCDF to GeoTIFF by layer in r

[Ahmed Attia]

Hi

I have a netCDF file of volumetric soil water content at four
different soil layers and want to convert each soil layer in the
netCDF file to a GeoTIFF layer. This code converts the netCDF file to
one GeoTIFF layer, i.e. unclear which soil depth.

file.nc <- "C:/Soil_Weather_data/Agro/VMC21/VMC21.nc"

file.tiff <- "C:/Soil_Weather_data/Agro /VMC21/VMC21"

importnetcdf <- raster(file.nc)

> importnetcdf
class       : RasterLayer
band        : 1  (of  4  bands)
#the bands here are the four soil layers
dimensions  : 16800, 43200, 725760000  (nrow, ncol, ncell)
resolution  : 0.00833333, 0.00833333  (x, y)
extent      : -180, 179.9998, -56, 83.99995  (xmin, xmax, ymin, ymax)
coord. ref. : +proj=longlat +datum=WGS84 +ellps=WGS84 +towgs84=0,0,0
data source :
C:\FAPSEP_Eucalyptus\FAPSEP\Soil_Weather_data\Agro_IBIS_Eucalipto\VMC21\VMC21.nc
names       : Volumetric.water.content.at..33.kPa
z-value     : 4.5
zvar        : VMC2



VMC1<-writeRaster(importnetcdf,filename="file.tiff",format="GTiff",overwrite=TRUE,bylayer=TRUE,suffix="1:4")
   #bylayer=TRUE, did not work.

> VMC1
class       : RasterLayer
dimensions  : 16800, 43200, 725760000  (nrow, ncol, ncell)
resolution  : 0.00833333, 0.00833333  (x, y)
extent      : -180, 179.9998, -56, 83.99995  (xmin, xmax, ymin, ymax)
coord. ref. : +proj=longlat +datum=WGS84 +no_defs +ellps=WGS84
+towgs84=0,0,0
data source : C:\Users\Ahmed\Documents\file.tif
names       : file
values      : 2, 80  (min, max)

Any help!
