GMT grdfilter 參數說明(beta)

-D
輸入的 grid 檔與給的 width 若單位不同,可用-D0~5 來設定
-F 設定要使用的過濾器
-G
輸出檔的格式及設定,每個值的輸出會乘上 scale 再加 offset,id 代表的是 grid 的格式或 精度?,可查閱 grdreformat,nan 表示空資料要用什麼值來代表。
grdfilter -Gid/scale/offset/nanFIlename
-I
x_inc [and optionally y_inc] is the output Increment. Append m to indicate minutes, or c to indicate seconds. If the new x_inc, y_inc are NOT integer multiples of the old ones (in the input data), filtering will be considerably slower. [Default: Same as input.]

-R 代表輸出檔案要輸出的區域west/east/south/north
-T Toggle the node registration for the output grid so as to become the opposite of the input grid [Default gives the same registration as the input grid].

Example:
ncku_grdfilter -V -D0 -S10 -Fg600 snan.grd -Gdnan600.grd
