解决办法
Starting at ArcSDE 9.2 it is possible to specify band level nodata values for the sderaster -a option. Therefore for the type of RGB data provided in this example it is possible to achieve the nodata values by applying the sderaster -a 255,255,255 option. Since it is unnatural to have a pure white value of 255,255,255 for this type of imagery, it is unlikely that any real pixel values will be changed to nodata.
