今、NetCDFファイルに変換したいと思います。私は

asc = import.asc("/Users/Pushp/Desktop/test/CF/2004/Eta-20040101-India-RH50.asc")

を使用した.ascファイルをインポートした後、今、私はnetCDFファイルには、このラスターファイルを変更したいラスタ

raster = raster(asc)

に変更しますか?

答えて

0

あなたは行うことができます。

library(raster) 
asc <- raster("Eta-20040101-India-RH50.asc") 
x <- writeRaster(asc, "eta.nc")
