I want to linear stretch my raster grid formate having column/rows 3128, 3503 with 30 meter resolution by using the following syntax in raster calculator of arcmap 10.1.
("raster" - FocalStatistics("raster", NbrRectangle, 30, 30, "Minimum") / (FocalStatistics("raster", NbrRectangle, 30, 30, "Maximum") - FocalStatistics("raster", NbrRectangle, 30, 30, "Minimum"))
But this gives me the error while executing. I have also tried the simple equation but did not work.
("raster" - min("raster")) * 1.0 / (max("raster") - min("raster")) + 0.0
