(1)将特定值(-9999)赋值为0
Con("raster"==-9999,0,"raster")
(2)给空值赋予特定的值(如0)
CON(ISNULL("raster"),0,"raster")
(3)将特定的栅格值(如1)赋值为空值
setnull("raster"==1,"raster")
(4)提取栅格数据中特些定值
(1)Pick("raster",[1,2,3,......])
(2)Slope>15,提取Slope大于15的格子,赋值为1,其余为0
(3)Con("Slope">5,"Slope"),提取Slope大于5的格子,值不变
(4)工具箱中Math下面的greater工具,结果为1和0
(5)将栅格数值在某一条件范围内(如小于0)赋值为0
Con("raster" <0,0,"raster")
(6)平方和开方运算
(1)Power(raster,2),Power(raster,0.5)
(2)Squre(),SquareRoot()
(7)使得影像中的多个值赋予无效值
SetNull(("raster == -32768)|("raster" == -10000),"raster")
