This map shows an image that was enhanced using both Imagine and ArcGIS. The first problem was to reduce the visibility of striping that occurred in the Landsat7 image. Fourier Transform is a process that reduces the banding, although it can still be seen. Further use of filters and adjustment of the histogram improved the contrast and detail, allowing the viewer to be able to see edges more clearly, and to be able to identify areas of vegetation, water, and urban or residential land use.
