Hi, As a new user of ER Mapper, I was looking to use a low pass or smoothing filter on some aeromagnetic data. In general there are some processes I wanted to try that are not available in the ER Mapper package that someone might have developed for the same purpose. 1) An upward continuation process in with which one can specify the height to continue to. 2) A low pass/smoothing filter that doesn't shrink the image (Using a wrapped version of the image, a constant outside the dataset, or any other method to avoid this problem (I don't mind the edge effect, but I would like some form of data instead of null values). 3) A smoothing filter with which one can specify the number of iterations required (20-450?). Thank you for any help you can provide.
