I wanted to convert Nodata value into 0. Because Nodata value of my image is really lower than valid range, which is -3.4028234663e+038. Then I used Con and Isnull statements on raster calculator in ArcGIS. But it didn't work, the Nodata value of output image is still the same with before it was. Can you tell me why it didn't work? Here is the calculation: 

Con(IsNull("tmp_2000.tif"), 0, "tmp_2000.tif")

Does the output image actually contain any NoData cells? (It's possible the problem is with how ArcGIS symbolizes the result rather than with the contents of the result itself.) – whuber♦ Dec 8 '12 at 18:36
